Question for the welders

[Graybow]

I have a problem with my welder. It starts and runs fine. But when you touch a rod to the metal it produces just a trickle of electricity. It will rev up when you do but just no output. Is it brushes?

[Draco]

It could be but I would certainly check all contacts between the lugs on the machine and the stinger and ground clamp.

My 235 Miller was doing that and it was the fine setting knob.Replaced it and has been working fine.

[Graybow]

Don't think that's the problem. I should have stated also, that the outlets barely have any electricity, also. You plug something in and it barely runs.

I can't remember what it is called, but it's probably in the board. My Lincoln had the same problem a few years back. If it is this, it's a simple fix. Just wished I could remember what we did. Wanna say it was a loose connection somewhere in the board.

What welder?

[Ironman]

Was going to say rheostat, but with the weak outlets, sounds like a generating problem. Depending on what welder it is, that could be caused by several different things.

It can be multiple different things that can cause that. What machine, year model and how many hours?

[flatlander]

Take a look inside the machine at the armature. Since it's both the weld output and AC/110v output it possible that the copper has a fine coating of corrosion.

Buy a 'seater brush' from any welding supply store and while the machine is running gently hold the brush on the armature.

While you are in there check the brushes for wear, but it's probably just corrosion.

If it was just weld output it could point to other things like a board or rheostat/potentiometer (fine adjustment knob) but since it's both you probably need to go straight to the source.

Does the engine rpm increase when you strike the arc? If not google welding machine exciter.

Yes it does rev up when y
I try to weld.

Thanksw for the help and info guys. It is a Lincoln Ranger 10,000 with a little over 500 hours. It was welding just fine the day before. I fired it up and had this problem. Appreciate the help

Could be just operator error!!!! Does it have a switch to change from weld to using the electricity? If so that may need to be switched back or the switch itself may be bad!

LOL always one in a crowd!

When you turn that "switch" on, it basically just kicks it out if idle and sends full current.

Could be a loose or broken wire internally. Shoot Dozer a pm, he's a ton of help.
