Yep. can also relate, our weldbooth had numerous welding machines in it.
with various gases and mixtures for each.
Argon & Argon/2% hydrogen mix for the plasma welder
Argon or helium for the TIG
along with an argon/helium mix.
Argon/carbon Dioxide for the MIG
Had to keep LARGE labels on each tank to keep them separate.
and a sign to remind the users to CHECK the gas before welding.
got so tired of listening to folks that used the wrong gas for their
job/matl. they kept blaming the machines when things did,nt go right..
