What Is Stick Welding? Learn the Essential Basics of Welding With This Simple Starter Guide

Stick welding, formally known as shielded metal arc welding (SMAW), is often the first skill a welder learns, and for good reason. It is the "all-terrain vehicle" of the welding world: rugged, portable, and capable of joining thick steel in the middle of a windy field just as easily as in a high-end fabrication shop.

While modern tech has brought us fancy MIG welding and TIG welding setups, the humble welding rod remains a staple because it simply works when other methods fail. Welding is one of the most essential skills in modern industry, and stick welding is the backbone of that world.

In this guide, we’re going to break down exactly how this arc welding process functions, the gear you need to get started, and the pro tips that will help you lay down clean, strong beads without the frustration.

What Is Stick Welding?

The Science Of The Electric Arc

What is stick welding at its core? It is a manual process where an electric arc is struck between a consumable metal electrode and the base metal. This arc burns at incredible temperatures — reaching 6,000°C to 10,000°C, which translates to roughly 11,000°F to 18,000°F — to melt both the welding rod and the workpiece. This arc melts the materials to create a weld pool that, once cooled, forms a permanent weld joint. Because it is a manual arc welding process, the welder must manually feed the rod electrode into the molten metal as it is consumed.

How The Flux Coating Protects Your Weld

Unlike gas metal arc welding or gas tungsten arc welding, stick welding doesn't use a carbon dioxide or argon cylinder. Instead, the metal electrode features a thick flux coating. As the flux coating melts, it disintegrates and gives off vapors. These vapors serve as a shielding gas or gas shield to protect the weld from oxygen and nitrogen in the air. This built-in protection is why stick welding creates such reliable results without needing an external shielding gas.

The Way Protective Slag Forms

As the molten flux cools, it floats to the top of the weld metal and hardens into a layer of slag. This acts like a protective scab for the finished weld. In the manual metal arc welding world, cleaning this slag is part of the job. Once you finish your weld bead, chip away the slag to reveal the metal arc weld underneath. While it makes the process a bit "dirtier" than laser welding or gas welding, it ensures the weld penetration is deep and protected.

Why It Is Called A Constant Current Process

A stick welding machine is designed as a constant current power supply. In a Constant Current (CC) system, the machine tries to keep the Amperage (current) steady. When you change your arc length, the Voltage changes significantly, which affects the total heat input (Watts = Amps x Volts).

The Manual Feed Requirement Of SMAW

In shielded metal arc welding, you are the motor. Unlike a wire-fed MIG welding gun, you must constantly move your hand closer to the work as the consumable electrodes burn down. This welding process requires a steady hand to maintain a stable arc. Because you have to stop to replace the stick rod frequently, the "operator factor" is only about 25%, meaning a lot of time is spent on prep rather than active arc welding.

When Is Stick Welding Used?

Conquer Outdoor And Windy Environments

Because stick welding does not require an external shielding gas, it is the king of the outdoors. You can perform manual metal arc welding in high winds without the shielding gas blowing away. This makes it a versatile method for on-site repairs where gas metal arc welding would simply fail.

Dealing With Rusty Or Dirty Metal

One of the best welding techniques for old equipment is using a 6011 welding rod. Stick welding allows welding through rust, paint, or grease. The aggressive arc burns through surface contaminants, saving you hours of cleaning time. This is why it is the top choice for heavy equipment repair and farm maintenance.

Heavy-Duty Structural Steel Projects

For structural steel and thicker materials, stick welding is hard to beat. It provides deep weld penetration, ensuring the weld metal is fused into the base metal. Whether it’s structural welding for a skyscraper or a bridge, the manual arc welding process is trusted for its massive strength.

Pipeline And Pressure Vessel Construction

Pipe welding requires a welding process that can handle various angles. Stick welding is widely used in the oil and gas industry because it produces high-quality welds on carbon steel and stainless steel pipes that must pass X-ray inspections.

Maintenance And Emergency Field Repairs

Stick welding is portable and can be set up quickly. Since the stick welding machine doesn't require gas cylinders, you can take it to tight spaces for on-site repairs. From shipbuilding to mining, it is the most common welding method for keeping the world’s machinery running.

Essential Gear You Need To Start

High-Quality Welding Helmets And Lenses

To master arc welding, you must see the weld pool clearly. Use premium auto-darkening welding lenses and clear lenses that allow you to see the difference between the molten metal and the slag. Better visibility improves arc stability and results in a cleaner weld bead. If you are still figuring out which lens tone works best for your eyes and lighting conditions, this welding lens color guide breaks down everything you need to know.

Protective Clothing And Heavy Leather Gloves

Stick welding produces more sparks and spatter than TIG welding. A dependable welding helmet matters just as much as gloves, and you can see different helmet styles here: You also need a heavy jacket and leather gloves to protect yourself from the electric arc and flying molten metal. Safety is the most important part of any welding setup.

Chipping Hammers And Wire Brushes

Since stick welding is a "dirty" welding process, you need tools to clean the finished weld. A chipping hammer removes the hardened flux coating residue, and a wire brush cleans the weld joint so you can inspect your work.

Electrode Storage And Rod Ovens

Low-hydrogen electrodes, such as the 7018, are sensitive to moisture. If they get damp, they won't provide a stable arc. Using a reliable rod oven keeps your stick electrodes dry, ensuring high-strength results in structural welding.

The Correct Power Source And Leads

Your stick welding machine should have a reliable electrode holder (stinger) and a strong ground clamp. High-quality cables ensure the welding current flows perfectly from the machine to the metal electrode, preventing electrical voltage drops.

Choosing The Right Welding Electrodes

Decode The Numbers On Your Rod

The American Welding Society (AWS) classifies every welding rod. For example, in a 7018 rod, the "70" means it has 70,000 psi of tensile strength. The "1" means it can be used in any welding position, including overhead positions.

The 6010 And 6011 Deep Diggers

These are the go-to consumable electrodes for dirty mild steel. They use a cellulose-based electrode flux that penetrates deeply into the base metal. They are perfect for the first pass in pipe welding or fixing rusty tractors.

The 7018 Low-Hydrogen Smooth Operator

Known as the "king of sticks," the 7018 is used for structural steel and thicker metals. It contains alloying elements that make the weld very strong. It requires a stable arc and is best run on AC or DC current, depending on the machine.

The Beginner-Friendly Rods

6013 is generally considered a great filler rod and was once the best choice for beginners. However, although 6013 is easy to strike, many modern instructors avoid it for beginners because the slag is highly fluid and can easily become trapped in the weld (slag inclusion). Most students now start with 7018 (for puddle control) or 6010 (for arc control).

It’s easy to strike an arc and is often the first rod electrode students use when learning manual metal arc welding.

Match Rod Diameter To Metal Thickness

You must match your welding rod to the thickness of the metal. While stick welding isn't usually recommended for very thin sheet metal (where TIG welding shines), using a smaller diameter rod allows you to work on thinner metals without burning through.

How to Set Up Your Machine Correctly

Find Your Target Amperage

Setting your stick welding machine to the right "heat" is vital. If the amps are too low, the welding rod will stick. If they are too high, you’ll get excessive spatter and might blow through the base metal.

Understand DCEP Vs DCEN Polarity

Most shielded metal arc welding is done on DCEP (Direct Current Electrode Positive). This adds more heat to the filler metal, helping it melt smoothly into the weld pool. Some stainless steel electrodes or special cast-iron rods may require different settings.

Set Up Your Work Area For Safety

Before you start arc welding, clear away any flammable materials. Stick welding throws a lot of sparks. Make sure your ground clamp is attached to shiny, clean metal to ensure the welding current is consistent.

Organize Your Cables To Avoid Drag

When performing manual metal arc welding, you need total control. Drape the cable over your shoulder so the weight of the electrode holder doesn't pull on your hand while you are trying to maintain a steady arc length.

Lighting And Positioning

Whether you are in a flat or overhead position, you need to be comfortable. Proper lighting, combined with a premium gold welding lens, ensures you can see the arc stability and adjust your welding techniques on the fly.

Step-By-Step Technique For Your First Weld

Strike The Arc Without Sticking

Striking an arc in stick welding is like lighting a match. You quickly scratch the metal electrode against the base metal and lift it slightly. If you go too slow, the rod will "cold weld" itself to the plate.

Maintain the Correct Travel Angle

For most arc welding, you want a "drag" angle. Tilt the welding rod 5 to 15 degrees in the direction you are moving. This pushes the molten flux and slag away from the leading edge of the weld pool.

Control Your Travel Speed and Puddle

If you move too fast, the weld bead will be thin and weak. If you move too slowly, the molten metal will pile up too high. You want a consistent speed that creates a weld bead about twice the width of the iron wire core.

Manage The Changing Length of the Rod

As the consumable electrodes burn away, the rod gets shorter. You have to move your hand closer to the weld joint at a steady rate to keep the arc length consistent. This is the hardest part of the manual metal arc welding process to master.

Re-Starting An Arc On An Existing Bead

When you switch to a new welding rod, you have to "tie in" the new weld to the old one. Strike the arc slightly ahead of the old weld bead, then move back into the crater before continuing forward.

Stick Welding Amperage & Rod Selection Chart

This table covers the most common rod sizes and their "sweet spot" settings for mild steel.

Quick Settings by Rod Type

Not all rods burn the same at the same amperage. Here is how to fine-tune your machine based on the rod you've picked:

• 6010 / 6011 (Deep Penetration): These like it a bit colder. If you are using a 1/8" rod, try 75–100 Amps.
• 7018 (low-hydrogen): They like it hotter to keep the puddle fluid. For a 1/8" rod, try 110–130 Amps.
• 6013 (General Purpose): These are the "middle ground." For a 1/8" rod, try 80–110 Amps.

How to Read the "Signs" While Welding

If you don't have a digital display on your welder, watch the puddle and the sparks:

1. Too Cold (Amps too low): The rod sticks to the metal constantly, the bead is "tall" and rope-like, and you have poor penetration.
2. Too Hot (Amps too high): The arc is extremely loud, sparks (spatter) are flying everywhere, and the rod might start glowing red before you're finished.
3. Just Right: The arc sounds like bacon frying, the slag peels off easily, and the edges of the weld tie into the metal smoothly.

Note: Always ensure your machine is set to the correct polarity. DCEP (Electrode Positive) is the standard for 7018 and 6010, providing the best penetration and arc stability.

Common Problems And How To Fix Them

Identifying And Preventing Porosity

Porosity looks like tiny holes in your weld metal. It usually happens if your low-hydrogen electrodes are damp or if your arc length is too long. Use a reliable rod oven to keep your rods fresh.

Avoiding Undercut Along The Weld Toes

An undercut is a groove melted into the base metal next to the weld. It happens when your welding current is too high or your travel speed is too fast. Slow down and let the filler metal fill the edges of the weld pool.

Fixing Excessive Spatter Issues

Stick welding is inherently a bit messy, but excessive spatter indicates your arc is too long or your heat is too high. Keeping a tight arc length will keep the molten metal in the joint where it belongs.

Dealing With Slag Inclusions

This happens when molten flux gets trapped inside the weld. It usually occurs if your welding techniques are off or if you didn't clean the slag from a previous pass. Always use a wire brush between layers.

Managing Heat Distortion In The Metal

Because the electric arc is so hot, it can warp thinner metals. To prevent this, use "tack welds" to hold the weld joint in place and allow the metal to cool between passes.

Frequently Asked Questions About Stick Welding Basics

Can I Stick-Weld Aluminum Or Stainless Steel?

Yes, you can! While TIG welding is more common for these applications, specific stainless steel electrodes and aluminum rods are available. For cast iron, specialized rods with high nickel content are used to prevent cracking. However, aluminum stick welding is notoriously difficult, messy, and rarely used in industry because the rods "burn" incredibly fast and the flux is highly corrosive.

Is Stick Welding Stronger Than MIG Welding?

For pure weld penetration in thicker materials, stick welding is often preferred for heavy structural welding. However, both methods are incredibly strong if done correctly by a skilled operator.

Why Does My Welding Rod Keep Sticking To The Metal?

This is usually caused by having your welding current set too low or by not striking the arc quickly enough. It’s a common hurdle for beginners learning the basics of manual arc welding.

What Size Breaker Do I Need For A Stick Welder?

Most hobbyist stick welders run on a 30-amp to 50-amp breaker. Always check your stick-welding machine manual to ensure your electrical system can handle the electrical voltage and current.

How Do I Know If My Rods Have Too Much Moisture?

If the arc burns unevenly, pops frequently, or if the slag is hard to remove, your electrode flux may be damp. This is why pros use rod ovens to protect their low-hydrogen electrodes.

Do I Really Need A Specialized Lens For Stick Welding?

Yes. Because stick welding produces a lot of smoke and a very bright electric arc, a high-definition lens helps you see through the "fog" to monitor your weld pool accurately.

Can I Stick-Weld Thin Sheet Metal?

It is very difficult. Stick welding is best suited for thicker metals. For very thin sheet metal or thin materials, gas metal arc welding (MIG) or TIG is usually a better choice.

What Is the Easiest Stick Welding Position For Beginners?

The flat position is the easiest. Overhead welding and vertical welding are much more difficult because gravity tends to pull the molten metal out of the weld joint, requiring advanced welding techniques.

Final Thoughts

Stick welding is a "feel" sport. It takes practice to coordinate your hand movement as the rod physically disappears into the puddle, but once you find that rhythm, you can weld almost anything, anywhere. To make the learning curve easier, ensure you aren't fighting your equipment.

Using high-quality lenses will ensure you see the difference between the molten flux and the actual weld pool, while a proper rod oven ensures your stick electrodes perform exactly how they were designed to. Whether you are doing structural steel work or heavy equipment repair, mastering the manual metal arc welding process is a skill that will last a lifetime.
