 Who's Got Gas??
For those of you that have MIG and/or TIG welding machines, what gas or gas mixtures do you use? If you use mixed gas, do you have a gas mixer or do you get it pre-mixed? What gas or mixed gas (and what percent of what gases) do you use on what material? ie- TIG, 100% ARGON for everything; MIG, 100% CO2 for plain carbon steel in short-circuit transfer; MIG, ARGON/HELIUM/O2 for stainless steel.
When I TIG at school, we use 100% ARGON with everything (plain carbon steel, stainless, aluminum). With MIG, we use 100% CO2. But sometimes, with the welders equipped with gas mixers, we mix ARGON and CO2. We only MIG plain carbon steel. Depending on what I'm welding is used for, I use either 100% CO2 or 65% CO2/35% ARGON (my personal preference).
