Depends what thickness material you are going to be welding, if everything you are doing is up to 5mm you want to go for a 5% CO2 mix, if you're going to be doing heavy section material (above 8mm for example) you want 20% CO2 and if you're doing a range of thickness's I'd go for a 12% mixHi, I used a power setting of 3 0.8mm wire and about 10-12 cfh on the argon mix. I did one weld perfect but I had no idea how I did it I guess a fluke more than anything else. I will be changing my gas setup for a bigger one as the smaller ones are rubbish and don't last anytime.
Trouble finding Gas
I wanted to buy 75-25 argon mix but could only get 80-20 any ideas on what gas I should get?
