Lincoln 140C will not turn on.⁰

[Enigma]

hello I was hoping someone could help me get my welder working again. I've had it about 10 years and have never had a problem with it. I have not used it that much probably only put 4 or 5 spools through it. I always use MIG.

went to use it couple days ago. went to turn it on like normal. flipped the on switch and nothing. no sign of life. checked the outlet and it's 120v. checked the reset button and it's not sticking out.

is there an easy fix? what could be wrong?
thanks.

Hello E! I hope all is well with you and yours.

Try this, with the machine unplugged from the power outlet, cycle the power swithch on and of a few times. Sometimes what happens is that switches especially the ones that run a few higher amps at an almost at micro level start pitting and as the electric amps keep going through causes valleys and peaks almost at micro level on the switch contacts which get filled with burnt material from the contacts.

Operate it a few times and let it do the hard snap from the switch spring. Sometimes that will clear the soot/coking/carbon build up.

If that does not work uncover your machine. With your tester make sure you have power to to ground one side of the switch and then turn on the switch and make sure you have power to ground the other side also. If when you switch on the switch and no power then more than lokely it is your power on witch.

If you do not feel confortable to do it with the power on do it by checking continuity with your tester. Best of luck !

Be well and stay safe out there.

Best wishes to you and all of your loved ones always!

Thank you for suspecting the switch. I took the cover off of the welder and removed the switch. I ordered a new switch. When it arrived I checked the new switch for continuity and it was good, I then did the same test on the old switch and one of the poles was open so I replaced the switch with the new on and the welder now works normally again! Thank you very much. I paid 585 for it in 2008 or so and now the same welder is 1200 and the 180 is almost 2k!!

I am glad that you were able to get your machine going again!

You are very welcomed!

p.s. I like your Eye of the Tiger.
It reminds me of LSU.
Our son will be starting his Junior year there next fall. He is here for the summer.
