I just want to start out by saying that I have never welded before in my life and would like to learn how. That being said, I have a possibly dumb question... I have a Lincoln AC/DC225/125 arc welder and I can not seem to get it to turn on.

I checked the outlet and it has 245V being supplied to it. When I plug the welder in and flip the switch to on, nothing happens.. I'd assume I should hear the transformer humming or a fan or something. I tried to strike an arc regardless with no luck. I assumed something must have been broken in the welder because it has not been used in several years.

I took it to a welding shop to have it looked at and they told me it fired right up and worked fine. What am I missing???

I see on the welder that it says input: single phase 230V 50A.. I am unsure if my garage is single phase our dual phase, could this be an issue?

Any feedback would be great!
Thanks!

Are you using the ground clamp?

Yes the ground clap is attached to the stock I am trying to practice on. Shouldn't the welder be making some sort of noise?

I've read where about the only thing that ever goes wrong with those welding machines is the on / off switch. Just wonder if that might be the problem. :confused3:

Can you post a pic of the plug on the welder, and the outlet you are connecting to. That would help a lot. Could be your outlet is wired wrong.

Yes it should. It is single phase so you have the right power. Do you have an ohm meter? Taking the plug out, measuring between the two 110V prongs you should get some resistance (fairly low) with the welder power switch turned on. Maybe the switch is faulty.

Not sure, but is there a lever that one engages to change the settings? Maybe this has to be in the weld, not the adjust position. Just a thought.

who wired the plug

make sure the flat blades have power and the round outlet is the ground.

and yes, you should hear loud hum even if welding leads arnt plugged in.

my bet is on the outlet in the shop. especially if it works in other shop

I checked the resistance across the two prongs on the welder cord, it's an open when the switch is off and a few ohms when the switch is on which seems to be right. I took the face plate off the the outlet and took a picture, maybe that might give you some more insight.

Thanks for the suggestions so far, I am completely stumped, because the repair shop told me it worked fine..

Check voltage to ground on each leg.

Each leg to ground is showing 123V, so it seems that is okay. I don't know what else to check
