General rules, fine tune from here.
Steel- 1 amp for every .001 material thickness
Aluminum - 1.6 amp for every .001 material thickness
If MIG, then adjust wire speed to a smooth sizzling sound.
Deep fat fryer sound (intermittent popping )= wire too slow
Pushing your torch away from workpiece = wire too fast
Gas, same flow rate for all
Steel 25/75 Co2/Argon. 25 cfm or about 25 psi.
Aluminum 100% Argon or Argon /Helium mix - helium can help an underpowered machine
Stainless steel- Tri mix 2.5/7.5/90 Co2 Helium Argon
Excuse and correct any gas error, it's too early. I'll confirm later.
