SOURCE: Mig welder

Sometimes dirt builds up at the beginning of the liner, at the drive. Eventually the dirt jams in there so much that it gets very hard to push the wire through it. Carefully cut the wire between the spool and the drive and secure it to the spool through a hole, so it doesn't unspool into a bird nest, then disengage the drive roller, the wire should pull out of the tip freely. If you feel resistance when you pull it out, either there is dirt at the beginning of the liner, or the contact tip is causing resistance. Without the wire in the drive, turn on the machine and try it watching the drive. Does the drive work freely now? Does it change speed with the rheostat? If its a problem with dirt, this is what I do, after you get the wire threaded back through the drive, liner and contact tip, and everything is working, take a small clean cotton rag and simply tie it around the migwire between the spool and the drive, in a way that the drive can't **** it in. This will constantly clean any dust/dirt off the wire before it goes through your expensive drive and liner. Whenever you change the spool, change the rag. Hope this helps, and please post your results.

Hi,
Check the current control resistor with an ohm meter. The center terminal should have a smooth rise or fall of resistance when measured to one end or the other of the resistor. If the resistor and the wiring to it are OK, check the shunt in the output it'll be by the "electrode" terminal. If both are OK you probably have a bad control board.

Regards,
Carl

SOURCE: Welder not welding

SOunds like your ground is not connected solidly either inside the machine or at the ground clamp. Check to make sure the ground wire at the clamp is not broken then make sure the ground wire is connected solidly inside the machine.

I have the same welder. Worked well for 15 years until the drive bearing stopped spinning. I cleaned and oiled the bearing and it has been working like a coon on the farm since. Nice 120 volt welder....

Why does wire weld to tip when trigger is pulled when welding aluminium


The tip of the welder may need cleaned out, your feed speed might need slowed down, check the polarity is it straight or reverse?

I had this issue on my el-cheapo mig welder.The wire drive on the junk or the good machines is similar as far as how the wire is pushed down the liner.A pair of spring loaded wheels squeezes the wire,and one of them is turned by the motor.One of the wheels has a groove to keep the ire aligned.This groove is possibly worn out,and not gripping the wire enough.(My cheap welder,unbelievably,has a reversible wheel with a second groove.I turned it over,and it's like new again!).You should have no problem in getting a replacement wheel for a Lincoln machine.

MIG welder 250 feeding wire at erratic speeds


Gun trigger contacts or switch circuit is closing somewhere (shorting). Unplug connector and jump the two terminals if it works and will weld disconnect jumper if problem persists it is not in the gun or cable hose. Keep chasing it far as possible without taking bolts or screws out of machine unless you know what that stuff inside will do to you, pretty sure the problem is not in there anyway.

My welder does'nt feed a constant feed motor seems to slow down and wire pushes my hand away when hitting metal.


If wire pushes your hand away when welding you need to do one of the following:
Reduce your wire speed, or increase the voltage.

I am having a issue with the feed and the welder quits welding after about a inch of welding then will intermittently weld for a second or two then stop again. I use this welder to keep my family tractor...


First thing I would check is the relay that sends power to the transformer when you pull the trigger. That can be one of the hardest parts of a Mig welder to troubleshoot because you can read full voltage through the thing with a multimeter when the contacts are dirty and it's not functioning properly.

That's assuming you're losing power. If it's a feed issue then we can address that later.

Wire not feeding correctly


Check for the correct tip size first. Too small or too large portal will jam wire in the tip. Check for correct wire speed for amperage used, too fast or too slow coupled with the distance from work piece will do the same. Check for wire condition, if the wire is rusted......you do the math. Check polarity......DECEP vs. DECEN for the type of materials welded. ARE YOU USING AN ANTI-SPATTER AGENT? Build-up of spatter can cause early arc. Lastly, is the wire tension too high? The wire should not feed at all even with the motor drive unit running if the wire has fused to the tip, that leads to a kinking of the wire behind the feeder (spool side).......check also the backlash adjustment to keep the wire from spinning off the spool under load. Too tight will cause the outer cladding of the wire to strip off the core wire which will cause the core to adhere to the tip.

Having problem with heat range.


Try keeping your heat setting hot, but increase your wire speed and regulate your welding speed accordingly. How does the weld look with your settings where you started?
