So I picked up a little mig welder. My beginners welder if you will.. I set it up to practice on a fender laying on the table. Hooked up the ground to the fender and when I went to weld I got a huge spark off of the ground clamp...wtf? I figured before I went any further I would check in with the experts..Anyone? I cant imagine this is normal (IMG:style_emoticons/default/dry.gif)

I would go with the ground clamp first and then check the terminal inside the welder. Then check the gun supply terminals.
Reversed polarity shouldnt make it pop. I reverse the polarity with MIG all the time when welding upside down to keep my ear wax virgin. When welding make sure you have the proper stickout so the wire doesnt burn back and stick to the tip. Make sure you are not shorting the tip out on the material. Easy test to see if the board has a short or blown diode. Run about 5 inches of wire out and then touch the wire to the material and press the trigger. You should see the wire pre-heat and glow red if everything is ok. If your spool is old it can get rust deposits on the wire surface. It will sputter and pop. |
