Working on a utility trailer gate; adding some stiffeners to keep wheels from bending in the expanded metal.
I’ve ground off the paint where my welds need to go.
Using ER70S-6 030 attaching 14ga wall 1x1 inch square tubing to 10 gauge angle.
Wire is acting like there is a bad ground and taken different measures to address that but see no change. Wire pushes against clean metal sometimes with no arc. Most of the time it’s slamming against the material and piping as the arc established. Often times it’s burning through tubing.
I’m using a first generation Miller 211. I’ve tried auto set which is almost always too hot for reality and lowering those settings. I’ve also tried the chart settings and increment info them down as well. No change.
I know I need to change the current contact tip now and will today and see if that makes a difference. The liner is the original so, maybe?
The angle iron is kind of weird looking, in some cases having the appearance cast would have. It’s not smooth like good hot rolled should be. Is there such a thing as ‘bad steel’?
Does paint get buried in the work piece during grinding?
I put a piece of the tubing in a vise and beads run fine there under same wire and settings.
Thinking about throwing some 035 flux core at it.
