Lincoln electric ac/dc arc welder will not arc

This is not a simple question. Take this magnificent machine to a service shop.

Changes between AC and DC voltage at the electrodes.



Q: What Type Of Stick Welder Works Best For All-Around Use?

A: A welder with an AC/DC output, whether its an electric arc machine like Miller\'s Thunderbolt or a gas engine drive like Miller\'s Bobcat.

DC welding offers advantages over AC for most Stick applications, including: easier starts; fewer arc outages and sticking; less spatter/better looking welds; easier vertical up and overhead welding; easier to learn "how to weld" and a smoother arc. DC reverse polarity (electrode positive) provides about 10 percent more penetration at a given amperage than AC, while DC straight polarity (electrode negative) welds thinner metals better.

Q: Does An AC Output Have Any Advantages?

A: Yes, if you need to weld on material that\'s become magnetized from friction, such as when hay, feed or water constantly rub against a steel part. A DC output won\'t work because of "arc blow," where the magnetic field blows the molten filler metal out of the weld puddle. Because an AC output alternates between polarities, it enables you to weld magnetized parts.

Hi,

Any welding supply house can either get you a fan, or direct you as to where to find one locally.

--W/D--

Buyer beware. Contact the manufacturer and replace the needed parts.

my welder doesn't weld but my electric meeter goes wild.

The fan motor has probably burnt out, i see this alot...make sure the connections are good....you can try putting 120v to it directly, if it doesnt run you need a new one...if it does then you need to check all your connections

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

I took my old one to Grainger and they ordered a new one that is 230V. Total cost of motor and fan $27.00

sounds like you lost one leg of power to the unit,check power source and the the plug on the welder.

the fan should be pulling air from the front of unit and out the back.
