Hello All,
I am a newby to welding and am having alot of trouble. I have a Lincoln Electric Weld Pac 100 solder core wire feed welder. My problem is that I keep blowing holes in my metal. <img src="/forums/images/graemlins/scared.gif" alt="" /> I am repairing some rust spots in the bed of my 1987 Toyota 4x4 p/u. I want to do some other metal work on the truck as well, but need to find out why I'm blowing holes. <img src="/forums/images/graemlins/confused.gif" alt="" /> PLEASE HELP!!!!!!!!!!!!!!



What size of fluxcore filler are you running?

What grade of filler are you running?

If you are attempting this with the 0.035" E71T-11 filler that came with the machine it is going to be a hard task, basically the machine should be at the lowest voltage and wire speed settings on the machine and some quick tacks jumping around a lot.

Ideally you would use a gas shielded 0.023" hardwire filler with the MIG conversion and a cylinder of sheilding gas.
Barring that going with a smaller self shielded fluxcore filler size such as 0.030" would make life simpler.
