Lincoln Electric LE 83180 Century Professional MIG/Flux Wire-Feed Welder - Answered Questions & Fixed issues

There are several things that could cause this: 1. The relay (contactor) that switches on the arc is not closing and it could be bad. 2. The diodes in the power supply are bad. 3. The low voltage transformer is bad.

Hi:If your drive rollers are moving but can't push the wire all the way to the end of the gun, your problem could be the liner in your gun and/or the contact tip. Try to replace both. If your drive roller are not moving then check the trigger of the gun.

You can fix it yourself, take the potentiometer (also known as reohstat) out.You will need to open the machine and take the knob off to free it out. You can take the old potentiometer to any electrical shop, or go to your nearest welding shop/store I will recommend praxair store.

Buy a 220V/50amp standard switch and replace it. Any home depot has it.

Your drive tension is too light. There are rollers that the wire feeds through and they need to be tightened. They should push the wire through the gun but slip if you put the tip against a solid object and pull the trigger. If they do not slip, they will jam your gun. Give the tensioner another turn.

No, it's not going to be equal to the Lincoln in all ways- but if Lincoln built it it'll be a decent machine.

In all honesty, if you can only have one welder it should be a stick welder. Mig welders are full of problems and, while ideally suited to 8 hour a day 7 days a week use, can be finicky as heck when used infrequently.

The stick welder allows you to work in all positions and all conditions, it's generally cheaper than Mig welding and it's usually faster.

It shuts of because the machines over heats, or poor voltage.

Check voltage control potentiometer.

switch in gun is bad

try changing the tip and make sure your ground connection is good on the steel and in the machine sometimes the ground wire in the machine comes loose

You could have a poor ground clamp connection. Check that. also increasing the gas flow will cause turbulence at the weld, this can have a negative effect on weld quality.
Check your connections, check your liner, actually, replace it if you haven't recently.

From your local Lincoln welding supplier or lincoln direct.

They are on the market for both large and small applications. Chk with lincoln dealer.

My Century 225 mig has lost its power ...with adjustments to max it leaves a high weld deposit and low penertration.

What is the fix ?
