I am going to setup my PM215 for spray arc. first off what is the best gas for that welder for spray arc. I know 90/10, 93/7, and 98/2 will all work on the higher output machines, but will the gas be ok for my PM215. So what is the best gas for spray arc for my machine (keep in mind my machine max is 250 amps)
So I will need either a new tank with different gas in it. I have a few options
Option 1: Keep my 75/25 tank and get new tank with one of the three gas listed above.
Option 2: Just change over my 75/25 tank above to one of the three gases and just use that for my all welding and eat the extra cost of the gas.
Option3: dont buy anything new,keep my setup the way it is and just switch over my tig tank (100% Ar) every time for spray transfer.
So what would you all do it in my situation?
Thanks for any advice.
