by miles

wtt response,

slight changes in voltage and stickout can make a big difference in fixing wormholes.

try lower voltage only half a volt and increase stickout a little.

Worm tracks NEW

He has given you some good answer however this is really and out-gassing issue. Other common problems are moisture on the metal when you weld it. Also if you have to much gas flow on your regulator can cause this. We have had this problem and when I go out and look at the regulator they will have it cranked up as high as it will go thinking it will over come the fans blowing at them. If you turn it down between 30-45 cubic feet per hour may solve your problem. Hope this helps.
