I have the power mig 130 I just ordered a replacement whip and gun assembly for it and when it arrived it has three wire's a small blue one and a brown one then the large main black but my original only has two is it compatible or completely wrong for my welder

If you can afford it upgrade to the 140 or bigger. Tools are also a great investment. Don't buy cheap. Look at ebay for replacement parts for the 100. When you go to ebay look at the feedback % and how many times they have sold, not bought. I've had good luck there but I am very picky.Bryan

Hi:

Your gas nozzle is compatible with a tweco part number 21-50, this nozzle has the insulator included. You can find it at any Praxair welding store. Price is around 12.00 bucks.

Hi:

If your drive rolls need an extra pressure on them, that means you are using an oversize rolls, you did not mention what kind of wire is it (solid or fluxcore) probably your drive rolls are 035.
If youa re using fluxcore wire (no gas needed) the you should buy a knurled type roll that will cure the problem. Your machine is capable to weld up to 3/16" thickness using flux core wire or 10 gauge using solid wire-gas.

If this was useful to you please vote, thanks.

If you use argon gas the gun is positive and the clamp is ground/negative. If no gas is used then it is the opposite

make sure your drive wheels and contact tip is the right ones for the size of wire you are using. if your tensioner is too tight it will crush your wire and it will not feed through your contact tip.

loosen off your tensioner and remove any wire that has gone through your drive wheels.

It sounds like your soft arc or arc start exciter is going bad. This should kick up the engine immediately, when you strike an arc. If you keep the welder on a truck, this is a common problem. Although Hobart makes a fantastic machine, all welders kept exposed to the elements have this problem from time to time. Before replacing parts, I would clean ALL contact points and replace any that are burnt or pitted. Sometimes, it will save you a bundle.

As far as I know, they are made by Cebora which is an Italian company. Try welding-direct.com as well, you should be able to search for parts through them.

Good Luck!

Louis D Biasi You resurrected a 12 year old unanswered question which will now stick on the Homepage, 'Unsolved' despite being answered. It is always better to make a squeaky fresh, clean question of your own. The area where you posted is the 'Additional Information' information are so perhaps the OP can take his apart for you, but where the trigger connects should be pretty straight forward. Electrical schematics are available. Here are some manuals https://www.manualslib.com/brand/mishto/welding-system.html But is appears to also go by the name of 'Rossi'.

I have the same problem with the Mighty Mig...Did you find these resistor values?
