will not get complete pen.

[welderparrish13]

Welding carbon steel pipe in 6g and I cannot for some reason get penetration all the way thru. Any advice? I'm runnin 100 amps with a 1/8 gap. Outside visual looks great just not penetrating all the way thru..

1/16 land, er 70, root pass.

Tig btw

Any advice would be appreciated

Sry your root is 7018? If it is your amps a way high drop it to about 70 ( I know sounds low) and rotate the rod like your walking the cup with tig. And push it in there with good pressure and it should stack up inside

[pressurewelder]

Crap just saw you put down it was tig. Just jam that fillet rod in and watch your amps that seems a bit high

Try slowing down a bit and shorten your arc some

Make sure it keyholes for ya before ya move forward. No keyhole, no penetration.

Ok y'all I really appreciate it, I'll be sure to try that.
