Regulators

All my regs are  100% ArgonI have a large bottle of  50% Argon   50% Helium if I use an Argon Reg am i getting the correct CFM ?Thanks  Brett
Reply:No, but it will likely be close enough.With the cost of that mix, keep turning it down until you know you don't have enough and then turn it back a bit.Gas flow doesn't need to be rocket science accurate -- just make sure you have enough and don't waste the helium $$$.What are you welding?  I'm assuming DC TIG welding thick aluminum?Favorite right now is a Miller Syncro 200.Tons of tools and I blame at least one of them when things don't go right.

Reply:Thanks, its thick ally on ACMy tungsten's were melting  probably should go up a size
