After purchasing a DC TIG from eSCHEn, and spending an entire day in his company, enjoying good food and an informative chat, we got around to the subject of gases for TIG welding.
The standard is PURE Argon for most things, but Darren mentioned the use of Helium on DC for Alloy's, but couldn't be 100%, and neither could I for that matter - infact, other than being given a rather large cylinder of Helium to fill a couple of balloons a number of years ago, I knew very little about its uses to be honest.
Anyway, the first question I have regarding the use of Helium on DC TIG, is regarding the regulator. I've got to purchase another Argon/CO2 regulator for a big(ger) MIG that I'm building up again so it's not another purchase I've got to justify after my spending was reigned in!!
The threads on the Helium and Argon/CO2 cylinders seem to be the same, and the fill pressure is 200bar, the regulator is rated to 300bar, so in my head, thats alright?! Yes??
Or should I look out for a purpose Helium regulator?
Cheers,
Steve
