Welding upside down

[Rex_Kelway]

The advice of Rex is to leave the amperage set as normal, but up the wire speed about 8-10% (you'll have to fine tune this for your job as you go)

As for the technique, weld as normal but as the wire begins to burn back pause for a moment until the job cools (stops being red, maybe a second or so) then continue.

Usually this means that with your increased wire-speed you can weld 2-3 secs on then 1 sec off.

This is preferable to just cranking the wire-speed more to out-run the burn back, you'll just end up with ugly welds piled with spatter and unburned wire..

So how am i doing?
Welds are a bit messy and are not evenly spaced, etc, but they should do the job i think.

The black tube welded in joins the front and rear sections of the chassis rails where it stops under the rear passenger foot wells.

When I stitch welded my car I lifted the car onto it's side.. Maybe thats easier than learning to weld upside down?
