Aluminum SCH 40 pipe.

Tried the sch 40 again tonight. Cleaned it up on the lathe then with acetone. Made the pipe 4" long this time. Tried the freq at 60 -120 and the Balance at 30 % or lowest. Worked better but not getting the dime look at all. I can seem to melt the rod and flow it around but no stacking. I am waiting for some 1/16th rod to see if it will work any better. I think I need to focus the arc right in the middle to get a smaller bead. What`s the trick to narrow welds. Mine seem to be very wide once I can get going. Even if I back off the amps it is a fine line between melting or making a mess. It will melt the tig rod but not the pipe. I think I was around 85 to 90 amps max . It is definitely a improvement from the last time. I might take a hammer to the joint and see how it holds up.

Well hopefully in a couple of weeks I will have my new flex-loc torch in hand and give it a try. Just dropped $400 today on torch, consumables for the Tig, Mig and Plasma cutter. I talked to Everlast Canada and it looks like they will be carrying the CK line with super flex hose but not sure when it will be in stock. Jean figured sometime in Jan. To late for me but at least they will have more options.

saw post and misread the four inch long for four inch sch forty. if it was 4 in sch. 40 i would go to 3/32 or 1/8 th tungsten and 1/8 th filler.
