    125EZ - broken?

    I have a new 125EZ welder. When I turn on power to the unit, I hear a fan start. I can start a weld and weld for a few seconds, then stop. The fan continues running for a few seconds, then turns off. The welder is dead and won't weld. It is powered from a dual socket outlet and the other socket is still live. I turn off the welder, turn it on, still dead. Try again in a few minutes, and the fan starts and I can weld again. This cycle repeats - weld for a few seconds stop welding, fan runs then stops, welder dead, wait a few minutes, then can weld again. Am I doing something wrong?

    The welder is getting exchanged for another one. It's a fantastic welder when it works and I can't wait to get using it.

    Try it on a completely different circuit, fed through a different circuit breaker...just takes minute, and its quick and easy.

Or simply a bad fan motor. If less than 30 days stores will generally exchange but if its past that, this would be covered under Hobarts warranty.

    Thanks for all the advice. I will try again on Thursday morning with the welder on a different outlet and let you know what happens. For sure the fan is turning off and the welder is totally dead. I can check if it's a bad switch or fan.

    That would be my first guess too Rocky. When I first got my HH140 and was learning to weld with flux core, I had a habit of grounding out the tip, and she would not work again until I cleaned the tip to clear the short it was making with the wire.

    It's broke.

    Hobart warranty is excellent. Take 'er back 'n get a new one.

    Well, sounds like maybe the thermal protector is either defective, or something bad is happening inside the unit to cause it to get really hot. Did you buy this brand new yourself? or used? If brand new, I'd give Hobart Tech Support a jingle....
