Tried to continue welding floor patch in. Tried is the keyword.
Punched three new holes in OEM floor. before I
Using a HF internal flux welder. Flux weld is a bitch to grind down.
Quit before I made things worse.
Went back to honeydo's.
PS I really suck at welding. On my fifth spool of wire.
Get one of these, new or used. Lincoln pro mig 135. It’s good to 3/16”. I’ve penetrated 1/4” with a preheat.

Flux is fine for certain applications, but not ideal for sheet metal. I use this welder, on the same 30’ 10gauge extension cord, plugged into a 20 amp outlet, micrometer the metal I’m working and the settings chart inside the machine is spot on every time. Your ground also needs to be perfect or it effectively changes your machine’s “heat” setting. Length of wire out past the gun will do the same.
All of those variables matter. When doing thinner metal, I pull as opposed to push. A lot of people push mig and .035f, but I get the most even penetration when pulling. Also remember to shoot and move—stitch from tack to tack, then move to a new(cool) area. Even if you want to touch up a weld, come back to it once it’s cool again.
