I'll try to get some pics.. It doesn't make any sense to me that I can make a good weld on almost anything then the next weld I lay down looks like a gray ball of snot. I'm starting to think it might be a gas leak in the torch if I hold it at a certain angle? I don't know I'll try to get you guys so...

I have this problem on certain things and I can't figure out what it is. Most of the time everything's good but on things like filling a hole or welding pipe to a flat surface I get a gray ball of weld when I add filler it's like putting a fork in a bowl of melted cheese and trying to pull it out it...

I'm a little concerned about the bottom side of the pipe. I'm welding in 5g. I've tried different things but wanted to get opinions if I should feed the filler through the top tack through the keyhole. I've always done it feeding on the outside... Also I like a slight weave on the root pass. Forward...

This is what I was welding when it happened. It's a belt box on a mud motor. I didn't want to drill a hole because otherwise I would just have to fill it when I finished welding the crack and be in the same position with that grey snot haha.

Ok that's good news sounds like an easy fix..... Maybe!!

Okay will do. Thanks. I also have another question about filling a crack or a hole. I know your suppose to drill some kind of ventilation. But for what I was doing there was no way to drill. When I was just about to seal the crack my bead started to look like grey snot I couldn't add filler without ...
