This is for a new HLT (stepping up from a 10g cooler).
There are 5 1/2 couplers on it, all pulled. Some of the tig welds were real nice, others -erm, not so much.
Equipment - HF Tig, WP17 Torch w/ gas lens, 1/16" 2% Thor, 40a, 17cf Argon.
Most were friction welded. You'll see some "drops", because I used a piece of filler to start the arc (no HF here).
Here are a couple of pics. Comments welcome (I easily laugh at myself)..
Now for the tough question. The electrical (1 1/2") coupler. should I try and weld this in, or go with a weldless on this one.?
Reason: corrected size of tungsten
