I'm going to try this tomorrow and see how it goes. I will post an update. I'll try the 1/16 gap and 3/32 rod .cj737 wrote:What bevel angle are you using? About 35* is good for that thickness. Bevel to a fine point, no land. Set a 1/16” gap, four tacks. Grab your 3/32 rod and start washing it in. Remember as you travel uphill, the heat is accumulating quickly. Your picture shows a lot of sag on the inside, so I’d suspect too much heat or too wide a gap to start.
After the root, let it cool down to about 250* before you lay the fill pass.

With laywire it’s best if gap and wire are the same size. If the wire is bigger as in this case incomplete penetration is high risk. Either widen your gap to 1/8” or use 3/32” wire. 105-110 amps and you’ll do fine. Probably 110-115amps for the second pass.

Flat out like a lizard drinkin'
I will try that again. I did a 3/32 gap once and filled with 3/32 wire at 100 amps and it kept keyholing too much. I'll try moving faster.Coldman wrote:With laywire it’s best if gap and wire are the same size. If the wire is bigger as in this case incomplete penetration is high risk.
