20 Most Recent Hobart Champion 10,000 All-in-One 10,000-Watt AC Generator and DC Welder with Robin Engine #500433 - Page 6 Questions & Answers

Most welding supply stores have brushes.
But if they are obsolete you can make brushes from brushes that are close in oversize and proper configuration of connection

Hi, this symptom is indicative of a Power supply problem, and it is trying to start, and shuts down, and then tries to start again, the PSU is either itself faulty, or some "Other" component is faulty, and causing too much current draw, and the PSU, then attempts to shut down. The motor working, isn't that relevant, as the motor drive circuit is separate from the actual welding electronics so to speak. And may or may not work, has no real bearing on the actual welding electronics.
Honestly though, unless you have experience with these or other units, and welding electronics, really the best thing you can do, and it WILL work out less expensive, and less of a hassle, is to contact a Hobart repair center, and have them give you a "Quote" for the repair.
The only "Other" alternative, is to use the "Shotgun" approach to repair and swap boards, with the hope of getting lucky and actually repairing it. Ensure you DO isolate the actual l"Fault" though, otherwise, you may simply "Blow Up" the "Replacement" board(s). Obtaining a service manual, for your exact make and model, would be a great benefit if DIY was the way to go.

ensure the welding temperature switch is fully seated in its detents and not in between numbers or heat settings it will not run if inbetween.......

Part number you are looking for it is HOB 119264, You can order it thru any welding store near you. Try Praxair.

If this was useful to you please vote. thanks...

I have a suspicion. Remove the sheet metal housing (unplugged of course) and look for a large cylindrical object, probably in a clamp on the floor of the unit and it will have two large terminals with fairly heavy wires attached. It could be ~ 6-7 inches high and 3-4" diameter. It will have markings on it indicating capacitance and voltage and could be around 20-30,000 uFd and 60-70 volts. This is a filter capacitor and I have replaced several of the (naturally) Chinese units in other welder brands. Figure on $40-60 for a new one of these pieces of ****. They often do not even meet the given values by a large percentage but unfortunately, no American mfrs. have survived to compete with them. I have several large US made capacitors that are 30-40 years old that measure nearly like new.

Check the output voltage of the welder (the torch and earth clamp). The voltage should be around 30 to 40 volts. If yu see the normal spark from the rod as you strike, but cannot hold an arc, have a look at your rods, they could be old, damp or incorrect for your welder or the type of work you are attempting.

If your Hobart Mig is less than 250 amps then yes you can, bobcat 225 will give you10000 watts and you require at least 8000 watts for the hobart.

The part number you are looking for are:

203 476 . . . HUB, spool
203 544 . . . NUT, hub spool

Aks the sales rep at your nearest welding supply shop to order them for you. If you have a Praxair store go to them.

Price is around 20-30 bucks for both.

If you can feel the stream of gas coming out the gun, then could be that the gas it's contaminated. It happens. I sell gas for business.

change you contact box inside machine, if it does not have a contact control box, then your main pc board it's busted.

you need ar/co2 95 5 change contact tip to what ever size wire you r going 2 use .035 .045 whatever

Did you get all the gas needed for the different welding operations? I know you need a bottle of argon for the TIG welder, and a bottle of Oxygen for the plasma cutter? I don't even know, could be acetylene. The Mig welder uses either, gas or flux wire. When you have the gas in place with the Plasma cutter, ground your work, set the pressure on 50 psi and the amperage on 40, and let her rip. It cuts like butter. The Tig (Tungstun inert gas) is a stick welder for stainless, and the mig (metal inert gas) is for just about anything. But you probably know all this. I haven't read anything bad about it. It sounds like a good machine.
