Why won't my welder turn on?

Hi Jessica:
Right off, I get worried when untrained people start re-wiring. Please, PLEASE, don't try re-wiring as a learn-as-you-go project. Electricity BITES!!!!
Here's some basic starting info, but it's not intended as instructions for you to follow.
- 110 usually powers the lights so you've got 1/2 of the 220 working.
- 110 will be between the black (or red) and white.
- 220 will be between the black and the red.
- the white is called Neutral
- the green is Ground and is necessary for SAFETY
There should be some wiring instructions with your welder.
Hope this helps.

Rossi 220BZ Gas/Gasless Inverter Welder MIG MAG ARC Portable Welding Machine

The Rossi 220bz mig welder comes set up to use gas welding, that is with the Mig electrode connected to the positive terminal, inside the machine.
To use gasless mig wleding, the mig wire must be disconnected from the positive terminal inside the machine and reconnected to the Negative terminal - inside the machine. Open both the side coveres of the welder using a phillips screwdriver. Use a 13mm spanner to undo the hex nut holding the thick copper Mig lead to the terminal named positive, then lead it through the machine to the terminal on the oppisite side of the machine, labelled negative and screw it in place there with a 13mm hex screw. Be carefull not to bump any of the many electric parts inside the machine.
If you run the Mig welder in gasless mode with positive earth and positive elecrode it will blow the household electric fuse.
If you run the Mig welder in gasless mode with negative earth and positive electrode it will work, but the end of the Mig gun tip will get very very hot and start smoking abnormally from excessive heat.
But if you take the side covers off and rewire it (takes about 10 minutes) to negative Mig Electrode, the Mig gun tip remains cool and does not overheat. You will have to cut just one white cable tie, to get an extra inch or so of free Mig cable, so the thick copper Mig lead will reach accross to the terminal on the other side of the machine named negative. Stick the earth lead at the front in the positive terminal.
I did this on my Rossi 220bz mig welder.

I have a Migmatic 200 Canox (millar)ser# kb060228 and would like to purchace a spool gun to use with it . There is a 14 pin remote feeder plug on th front. Is there a spool gun available for it, or do I...

They make a spool gun for it, it has a round 7 pin connector like an RV trailer with braking would use.

If yours is truly a 14 pin, you can use your schematic and the one for the spool gun made for your machine to rewire it to work for you.

this is the manual for the gun that made for your welder:

I have a Hobart handler 120/90amp wire feed welder.When i try to weld,all i get is a small spark.I turn it off,turn it on and it does it again.The wire feed works good,it just sparks,but will not keep...

I have welded countless hours with Linde & Lincoln & even a few Hobarts & the only time that I ever had the same problem was when the ground connection either to the object I was welding, or the welding cable ground wasn't good & clean & tight. Same on stick welders also. I did develop the habit of grinding not only where I was preparing to weld, but where I was placing my ground clamp & that always provided a better "frying bacon" sound as I went along the business of pushing a bead. In a welder, the only other thing than that is involved is the step-up transformer and your wire. Hope this helps.
