A couple of thing to look at:
Your heat is probably too high.
Sheilding gas is the only way to go. You did not mention if this was a flux
coated wire you are using but if you are using non-flux coated wire AND no
sheilding gas, that is a no-no.
A small sheet of copper held to the back of the steel will hasten most burn
thrus.
Make sure you have a VERY close butt joint with no visable gaps between the
metal at the seams.
Go to my website and see the fender repair in the demo's section for further
information.

Subject: Wire Feed Welders
I borrowed a 110v Lincoln wire feed welder to do a few patches on my car.
The
machine seemed to be a better cutter than welder. At minimum feeds and
power
settings it would cut through the sheet metal in less than a second. I had
a
bare metal ground and the surface being welded was clean. I attempted to
back
up welds with a wet towel to act as a heat sink. Is inert gas necessary?
What am I doing wrong? What should I use to weld sheet metal to sheet
metal?
Any comments would be appreciated.
Bill
