I picked up an el cheapo mig from harbor freight. I put it in my horse barn so my dad can use it for his "yard art" projects. He was tired of walking to my shop to tack a few things now and then. It won't lay a beed. It only burns wire and splatters it everywhere. None sticks to metal. I have tried high and low power, all wire speeds and nothing works. Any ideas?

If it is a flux core welder, be sure the polarity is correct.

Like ecave mentioned, the polarity could be set wrong and that will mess them up for sure. Its also a possibility that the machine is about what 1/2 of Harbor Freights things are...POS Shocked

First thing to check is the recommended polarity of the type of flux core you purchased. Make sure you are running either DCEP ( wire feed connected to positive terminal) or DCEN (wire feed connected to negative terminal) depending on what your wire states.

Next I would check to make sure you have the right type of FCAW. FCAW comes in two types, FCAW-G (needs an external shielding gas) and FCAW-S (self shielding).

Next I would check the high/low settings on your welder for amount of voltage at each setting and find the correlating wire speed feed rate for the wire (proper size included) at those settings (should be able to pull up a sheet from wire manufacture's website). You can test wire feed speed by running the machine with trigger pulled for 10 seconds then measuring the wire used and multiplying by 6.

Lastly, I would check to make sure the drive rollers are not crushing the tube and leaking out the flux. Most MIG machines come with V-groove drive rollers and should only be used with solid wire at a fairly high tension. Knurled or U-groove rollers work better with soft wires and use a much lower tension.

Good luck.
