MIG Welding with 100% CO2 Shielding Gas

Ever wonder why some welders prefer MIG welding with 100% CO2 shielding gas instead of using a blend of argon and CO2 that’s designed for MIG?

Used to shield the weld from contamination, CO2 is plain-old carbon dioxide. It’s the same stuff used to extinguish fires, carbonate your beer and soda, and keep them cold.

The major advantage to MIG welding with CO2 is its low operating cost. But there are added benefits, along with a few downsides.

Flux Core Aluminum Welding Wire: What You Need to Know

Having trouble finding flux core aluminum welding wire?

You’re not alone. There’s plenty of confusion on this topic, and even some deception.

Also referred to as gasless aluminum welding wire, it sounds like a suitable option for a minor welding job. And one that can save you hundreds on welding gas and a spool gun. 

Plus, if your welder is a flux core only model, it’s your only option. Or is it?

What Size Welding Gas Cylinder for MIG or TIG? Argon|CO2

If you’re new to MIG or TIG welding, you may have no idea how much welding you’ll do—let alone how much welding gas you’ll go through.

But you’d probably like to have some sense of how long a welding gas bottle will last before deciding what size cylinder to choose.

I’ll show you how much welding time to expect from the most popular cylinder sizes used by hobbyists. Then you can compare physical dimensions so the bottle will fit your vehicle or welding cart.

What is a Tweco® Style MIG Gun?

How many innovative product designs can you name that have lasted half of a century?

In 1969, Tweco Products, Inc. (formerly Townsend Welding Equipment Company) introduced a new MIG assembly design. Tweco’s invention used a single cable to transfer gas, welding wire, and electrical power to the MIG gun. The MIG gun was also a new lightweight, cool-operating design.

Most MIG guns mounted on today’s modern MIG welders follow the fifty-year-old Tweco design. And, many product descriptions include the phrase “Tweco Style” when referring to MIG torches or consumables. Many buyers are left wondering: What is a Tweco Style MIG gun?

MIG Welding with 100% Argon Shielding Gas

Welders are problem solvers.

We can agree that running out of MIG gas in the middle of a project is a problem.

Since we also tend to experiment, you may have asked yourself if the gas kept on hand for TIG, or MIG welding aluminum could be pressed into service. Would MIG welding with 100% Argon on mild steel let you finish your project without a trip to the local (or not so local) gas supplier?

Or, is it possible to get by with one bottle of 100% Argon welding gas for all your MIG and TIG work?

What Shade Lens for MIG Welding? The Easy Way to Be Safe

Hands-down, my auto-darkening helmet is my favorite piece of welding safety equipment. I appreciate technology that not only makes a product safer but more comfortable and enjoyable to use.

Adjustable auto-darkening welding helmets protect your eyes from radiation and bright welding arcs with lens coatings and electronic shades from DIN 3 to a super dark DIN 14.

A light shade setting of number 3 or 4 provides enough visibility to position your MIG gun without having to lift your mask, but what shade lens for MIG welding?

How to MIG Weld Aluminum Without a Spool Gun

You’ve heard the horror stories about MIG welding aluminum without a spool gun—but you’re still thinking of giving it a try.

I get it. Spool guns are expensive and have drawbacks.

Sure, aluminum welding is tricky even if you’re using a $250 spool gun. But if you’re up for the challenge—and have a little patience—I’ll show you techniques and tips to use your welder to MIG weld aluminum without a spool gun.

And you’ll see how one of the most popular 120-volt hobby welding machine does on aluminum straight out of the boxwithout a spool gun.
