My name is rob, lets see if we can solve your problem

If the welders been working ok first question is what has changed, has it been moved or modified in any way?

Next, are ther any fuses or breakers fitted? are these ok?

Next, most engine driven welders have one major problem.

It shakes stuff loose, undos connections and damages static components,
Take some covers of to expose the internals and with THE ENGINE STOPPED check along the length of the cable harness especially at the ends of cables, give each terminal a tug with the cable to make sure there are no problems there. Also check the condition of the insulation of the harness along its lenght. at this point you may find a "hidden" in-line fuse somewhere in the harness if your lucky!

If none of this helps it gets a little more tricky, could you give me make and model? that would help a lot.

I have a Miller Bobcat 225. Engine and AC side OK, no welding output. Looking for a check list to troubleshoot with. I am able to do check with multi-meter. Just don't know values that are normal

Most common problem for no output is the brushes, you should also have approx. 3 ohms resistance across the slip rings. Can get you more info, but will require the serial number of the welder.

My TB 302 cranks and runs at high idle does not idle down. I have power at all recepticals but no power at welding leads. I have checked all breakers and fuses, they are ok. what do I need to do next

there are a few things you can check on your machine,
make sure your machine is not in the remote control position, make your process switch is in the electrode hot position, the trailblazer has three slip rings, make sure the carbon brushes are not "stuck" in the holders, there are 2 circuit boards in your machine, make sure the plugs are properly inserted into the receptacles and making good contact, also make sure your ignition switch plug is clean and making good contact

How do i fix have no welding output

If you expect anyone to even attempt to answer this, you need to at least say what brand and model. If a Miller, a serial number would be helpful. If a Lincoln, a code number (4 or 5 digit number)

Miller bobcat 250

remove the side doors, and top cover, make sure your brushes are making correct contact against the slip rings, there is a flat mounting panel behind the range control switch, you will see 2 white fuses in their holders, check these fuses, one controls AC output the other controls weld current output.

2003 tahoe alternator stops charging if i rev up to 3500 or 4000 and let it idle it starts charging

have the alternator removed and the slip rings on the rotor cleaned and machined . Replace the brushes and have the unit bench tested . When this happens it is an indication that the brushes cannot maintain contact with the slip rings either from lost spring tension --dirt on the rings and rings badly scored

Hi i have a Black max, Powermate Generator model #PM0496750 ,6750 watt it run great for 3 hrs and then stop generating,,, clean the frets on rotor where brushes runs on and its good for another 3 hrs then...

You have excessive arching on the rotor slip rings by the sound of it, if you clean them and it works well then 3 hours later same problem? What is the conditon of the brushes? Also I trust youa r enot cleaning polishing them with sanpaper etc, they have a very fine finish and should be polished with a super fine grit paper or stone, pref while turning the engine. Any scratches won't work

I have a hobart champion 4500, hard to strike an arc. what should i do?

Ensure your engine is in good running condition
The auto idle switch should function correctly
Remove the front cover of the welding generator, held by 2 1/4-20 screws
Behind that cover you will see a brush lock assembly, will have 2 wires connected at the top, one is insulated, one is not, mark the leads before you remove them to maintain correct polarity on the slip rings, the brush block is held in place by two Phillips screws, remove the screws, unplug the brush block,'remove it, check to see if the brushes move easily in the brush block, this is a common problem with these machines, the brushes tend to bind in the block, will not make proper contact against the slip rings.....
Remove the brushes from the holder, using a square of "scotch Brite" wipe the brushes, you may see a line around the brush, remove that by gentle cleaning, install the brush block, connect the leads, install the cover, go to work

I have a miller trailblazer 301g. It worked fine yesterday and now only the 120/240 volt outlets will work. No weld output and also the idle will not kick down. when I opened the unit the only visable...


Probably your machines just overloaded; the engine will run and produce voltage but no weld output.
Check your fuses F1 and F2, if they are open replace them.
Both fuses are located at left hand side of machine, open it and you will find them on the bracket.

Good Luck.

The generator works fine but there is no power output coming out of the 110 and 240 output

Look for a 'slip ring' assembly that turns against brushes when the alternator turns. Make sure the brushes are in good condition and have spring tension to hold then to the slip rings. Look for tripped breakers. Make sure the mechanical connection is intact between the engine and alternator. Service beyond this requires a schematic, or wiring diagram and the knowledge of what the diagram is telling you. Many of these units have circuit boards that control voltage output. Good luck!
