Gas Welders

When we talk about gas welders at ArcCaptain, we're referring to sophisticated electric welding machines that use shielding gas to protect your weld, ensuring strength, durability, and a clean finish. 

This collection features our top-tier gas powered MIG welder models (Gas Metal Arc Welding/GMAW) and precision TIG welders (Gas Tungsten Arc Welding/GTAW), as well as versatile multi-process units designed for every skill level.

It’s important to clarify: While engine-driven welders use gasoline or diesel for remote power, our focus is on electric welders that utilize external shielding gas for superior results in your shop, garage, or jobsite. 

ArcCaptain is committed to delivering reliable, high-performance gas welders built for quality, ease of use, and long-lasting durability.

What Makes a Gas Welder Essential for Quality Welding

Gas welders, specifically MIG and TIG machines using shielding gas are essential for professional results. Shielding gas protects the weld puddle from contaminants in the air, ensuring clean, strong welds with less spatter and a higher-quality finish. 

This makes gas welders ideal for a wide range of metals, including aluminum, stainless steel, and carbon steel, whether you're working in home welding, workshop welding, or industrial fabrication.

Frequently Asked Questions about Gas Welders

What is a gas welder used for?

A gas welder primarily refers to a welding machine that uses an external shielding gas to protect the molten weld puddle from atmospheric contamination during processes like MIG (Gas Metal Arc Welding) or TIG (Gas Tungsten Arc Welding). They are used for joining various metals, producing clean, strong, and precise welds with minimal spatter, making them ideal for automotive, fabrication, and artistic projects.

Is a gas powered MIG welder better than a flux cored MIG welder? 

A gas powered MIG welder generally offers superior weld quality, less spatter, and is suitable for a wider range of materials and thicknesses compared to a flux-cored-only MIG welder. While flux-cored is convenient for outdoor use or dirty metal as it creates its own shielding, the precision and finish of a gas-shielded MIG weld are typically preferred for professional and high-quality applications.

What is the difference between a gas arc welder and a stick welder? 

A gas arc welder typically refers to a MIG (Gas Metal Arc) or TIG (Gas Tungsten Arc) welder, where an external tank provides shielding gas. A stick welder (Shielded Metal Arc Welding or SMAW) uses an electrode coated with flux, which creates its own shielding gas as it melts. Gas arc welders offer more control, cleaner welds, and better aesthetics, especially on thinner materials, while stick welders are more robust for outdoor use and tolerate less clean surfaces.

What kind of gas do gas welders use and why? 

Gas welders use specific shielding gases to protect the weld. MIG welders commonly use pure Argon for aluminum, or Argon/CO2 blends for steel and stainless steel (CO2 helps with deeper penetration). TIG welders almost exclusively use pure Argon for most metals due to its inert properties, which ensure a pristine weld pool. The choice of gas impacts weld quality, penetration, and appearance.
