New to tig welding and have been reading about the benefits of using a mix of helium and argon for aluminum welding.
Two questions I have....
1. Can I get both argon and helium in one tank and use one reg instead of mixing from two tanks.
2. Is this mix of 50/50 also good for steel. I would not at this time get a second tank and buy an extra reg etc but if I could swap out my tank at the next refill for a 50/50 mix I would do that if it was still ok to use this mix on steel. If its no good for steel and or I can not get this mix in one tank I will hold off for now and put it on my maybe or wish list for down the road....thanks wayne
....enjoying my PM 205 very much. The switch over from oxy/ace to tig is very easy and love this little unit. If I can master Aluminum I will be very very happy.
