Just picked up a Lincoln 3200 HD. I was wondering what you guys recommend for the best shielding gas? 75% Argon/25% CO2? or Straight 100% CO2? Most, if not all, of my welding is on mild steel.

Hi bob,

Straight Co2 works just fine on mild steel. If your into Tig or Mig with other metals and want to keep one cylinder around then 100% Ar is a good choice and cost effective.

The reason I no longer suggest a mix is if you don"t use the mix right away, less than a year, then the gases will seperate inside the cylinder.

A single gas also will cost less than a mix, about 30% less.

There are wires out there that require different mixtures, like some of the flux cored ones that still use straight CO2, but the most common mixture for welding steel is usually gonna be the 75/25 mix of Argon/CO2. I"m not that familiar with the Lincoln power supplies, but if it"s a smaller machine and you find yourself needing to do alot of heavy welding you can jump to a 98/2 mix of Argon and Oxygen. This mix will make the arc alot hotter than is gets with the 75/25 mix, basically cheating and making the machine perform like it"s bigger than it actually is. We started using it on our Millermatic 200 a few years ago, when we needed a little extra boost, and it was like welding with a different machine. Where we had been having to set wide open with it we were able to turn down two settings on the dial. Then when it was set wide open the wire speed could be turned up making the same weld alot faster than it was origionally. The 75/25 mix is gonna be the most common and the most economical for general work, but the other is available if you don"t mind spending a little extra. Good luck and have fun with your new machine.
