Default Lincoln Ranger 250 Welder Makes 120V but no Weld

Hello all

We have a Lincoln Ranger 250 welder that has not worked properly for the 4 years I have known it.

We sent it to the Lincoln designated repair facility in Orlando Florida and they did some minor repairs and sent it back saying it was working.

The welder would not deliver the same heat almost like some on was turning the amp control knob it would decrees for a bit then return to the setting you started with.

Now after being run a week for 120V power for power tools on a construction project it will not weld at all but still powers hand tools.

We have purchased a 6 month old Miller from a large company that had purchased half dozen in order to complete a multi story building on time. It has only 150 Hrs on it. This unit welds very well and doesn’t have any of the problems this Lincoln has displayed.

Here are some pictures because I am unable to find a model and serial number plate.

Check the weld/power toggle switch for proper operation.

Probably runs at 2400 rpm for 120v output, but should kick up to 3600 rpm as soon as the arc is struck. If this is not happening, then welding current will be very low. Check "auto idle" switching and mechanisms. Regards,
Combustor.

Hi

akuna

The first number is labeled “K No.” the scold one is labeled “code” and the last one is labeled “Serial No.”
I have found the K number to be a sub model of the Lincoln Ranger model 250.
I am unable to find repair manuals.

Ed Radtke and Combustor

I now have the owner’s manual and will make sure the switches and knobs are set to the positions the manual calls for for the first use.

I will get back to you when I try the machine again.

How many hours are on the lincoln? I'd guess that either you have stuck brushes/dirty slip rings or a bad connection somewhere. If it has a ton of hours on it, then it's also possible that the brushes are just worn out.

Hi

Very few hours sense the last trip to a Lincoln approved repair facility.

Hi

I got a technician on the phone and we did some testing.

We found that one or both control boards are bad.

This machine is 16 years old and doesn’t bring much money when sold even if everything works.

So we will either use it for Ac power or scrap it.
