Question about Lincoln Welding Tools

Open Question

Hi I have a problem with my welder. My machine is in fairly good shape, I started a weld and when the wire made contact it burn straight to the tip of the nozzle. When I opened the welder side panel I saw that the wire reel locking nut that keeps the wire spool in place had come off and therefore my wire spool was loose and I beleive this is what caused the short out or whatever happened to the wire when it made contact. So my real problem is this. The machine sounds normal, when I push the trigger I hear the normal click in the gun trigger and the normal click in the machine that makes the drive roll wheels turn to pull the wire through. Both sound normal however, the metal wheels are no longer turning at all. The wire is not being fed though the hose anymore. Ive taken the gun apart and checked that and the trigger, the tip and nozzle. Everything is cleaned and no blockage. Im guessing that maybe I blew a fuse? However I cannot see anything inside the welder that would stop the wheels from turning. Opening up that part of the machine is past my knowledge. Can you give me an idea of what you think is the problem? thanks. P.S. are you able to receive pictures? Id be happy to send a snapshot of my welder when I open the side panel

the problem is your project is not grounded, attach the grounding cable from your welder to your project your welding.

SOURCE: power mig astro power 110 burns wire off at tip

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....

SOURCE: northern tool brand wire fed gasless welder feeds wire fan work no welding?

You need to have the ground attached to what you'll be welding on. Make sure there isn't anything on the end of your wire. Also, if your voltage is all the way down it won't do anything either. Oh, one more thing, make sure you have a contact tip on the end inside the cone. That will be the copper thing the wire goes through with a really small hole. I know some of this sounds pretty obvious but if I hadn't done these things at least once.....I wouldn't know what to look at either. I also don't know your experience level and want to cover all avenues. Hope you find it!

SOURCE: there is power to the welder and wire is being fed

Power and feed is not balanced. Gap to wide, or grounding of work and mschine is poor.

SOURCE: My Hobart Handler 120 stopped

Please don't give me a bad rating for this. Its just a little extra info. you didn't mention that may help you find the problem. Depending on your specific model, there should be 1 or 2 breakers on the unit it self. If there is only 1, it will shut down the entire machine when tripped. If there are 2, the top one is for the whole unit and the lower one is for the wire feeder motor only. There is also a thermal overload that will shut down everything except the cooling fan. Secure the trigger closed and let the fan run for a while to see if it re-starts when cooled. If the depth of the weld was stable before the problem occurred, I would suspect a short in the motor and not the rectifier. That is not a sure bet though. If the transformer does not start when it cools, UNPLUG the welder and short the transformer to ground to be sure the capacitor is discharged. Then isolate the feed motor and transformer and use an OHM meter to test them individually to ground for a short. With a little luck, it will be the feed motor. Please let me know if this helped at all. I am new and still learning how to explain what I am thinking. Thanks for writing us.

I have a craftsman 20511 mig welder it will start welding without pushing trigger


Elmer, If you remove the gun assembly from the machine, if the machine is now not feeding wire, the problem is most likely the gun trigger is faulty. The switch contacts heat up and start sticking over time. If able too disassemble and clean trigger contacts. Check the attached links,instruction and guides, Good luck

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?

Weld will not weld at a steady speed, it will weld good for a minute then start sputtering like it not getting wire and will burn the wire into the tip


Hi:

I think you have a problem with either:

Gun liner which could be kinked and need to be replace, or,

Drive rolls, make sure you are using the right size and right type for the wire used.

If using hard wire (gas wire) you should be using U-grooved drive rolls, if using innershiedl wire then V-knurled drive rolls must be in place.

I have a problem with a jerking motion while Im trying to weld. the wire feeds out good without the tip on. I replace the tip but I havent replaced the cup but Im using flux core wire also. What could be...


I have found that keeping the gun lead as straight as possible fixes this problem. Also it is sometimes recommended to use one tip size bigger when welding with flux core wire. My last spool was radnor flux core wire .030, and a .035 tip keeping the lead as straight as possible and it welded extremely well. If that doesn't solve it you should take everything apart and clean it / blow it out with compressed air.

My tig welder wont arc unless I touch the metal with it


my guess would be the type of welding machine you have.usually there is extra switch which says start control also continious cycle , sometimes smaller machines dont have these switches to allow a wider variety of tweeking the welder ,also its ok if you have to touch the base metal cause thats what starts the contact with the work peice ,keep a arc after touching about 1/4 inch away from work peice ,also a good steady hand rest will make a good welder in any situation this should allow the arc to remaim stable with a comntinious weld arc puddle. happy welding

I have a Lincoln Electric Power Mig 200 and I managed to get the frame of the welder touching the piece I was welding and I noticed it started to weld about half the time as though maybe half the rectifier...


I would guess that you are on the wrong track. Half of the diodes going out would cause problems 60 times per second, which would be too fast to notice. Unless the diodes all shorted and you're essentially running AC now, which is possible, but unlikely. When my wire feed "pushes" like that,it's usually because the tip is burnt or dirty and not making great contact with the wire. Try replacing the copper tip that the wire feeds through. If that doesn't fix it, look for a bad connection on the wire that runs from the diodes to the torch. Good luck.

Welder not welding


The contact tip is the main source of power, if the tip is bigger than the wire then you will not get a proper conection, the earth clamp is a essential part of the system make sure you have a good earth and all the conections are tight
