Welding thin metal

[bixtix]

just need a little help welding thin metal around 0.8mm with 0.6 wire, i can lay welds directly onto it with good penetration etc, but is it actually possible to butt weld 2 sheets together at this thickness, or would i have to use the stop and start tecnique. just playing at the mo, before i attack the sills on my ford probe. im using argoshield light btw

also what metal thickness should i use to repair the outer sills?

i have a siegen 180 turbo welder and ive seen a few reports of people not liking them, yes there is a problem and its the wire feed tension spring, its just useless, fit a heavier one and it works perfect,

im not new to welding but it been a very long time since welding and it was always heavey gauge stuff, the last welder i used was a massive 500 amp esab with a remote wire feed unit and digital adjustment which worked in increments or 1 amp

thanks for your time

Mark

I generally use the stop start technique on 0.8mm butt joins, though for overlap on 0.8 or anything 1.0mm or above I'd normally do continuous welds (short lengths normally to reduce distortion).

Best to use the same thickness as the original panel. Outer sills are often around 1mm, but vary between cars.

PS - in answer to your other question, currently it's necessary to private message weldequip on this forum for information about the Portamigs.
