Arc blow could be the cause! Put your ground on the work piece and weld away from it. If you weld toward a ground clamp the magnetic forces will blow your arc around sometime. When taking a cert this simple mistake can make or break ya on your cap or reinforcement beads.

Try moving the tip closer to your work and try turning your wire speed down
Most people want to crank up the wire speed when it spits and sputters
Turn it down
See if this helps

I have a Clarke wire feed welder than the wire is running but I'm having no Arc


first place to check is a properly grounded and connected ground wire to complete the weld circuit
next is to check the relay that energizes the weld circuit when the trigger is pulled
check for fuse blown
take it in for a proper diagnosis and fix

Wire feed is not stable on Hobart handler 135


is this a lower end machine ? the cheaper machines take the power from the welding transformer to power the feed motor and as a result the feed isn't stable, also is the wire liner and tip in good condition if not replace them, try blowing through the liner with compressed air to clear any dust from the wire

I have not used a wire welder very much. A friend encouraged me to try the one he had. I ran it out of wire before welding hardly any and when I tried to put the new spool in I could not get it to feed...


you may need a gun liner, if the liner is kinked the wire will not feed, causing a "birdnest" and if the wadded up wire touches the cabinet while the trigger is keyed it will get hot and try to weld wherever it is grounding e.g. the cabinet. try a liner first they are only 20 bucks

Wire feed is sticking when I try to weld. If I increase friction it only jams the wire. I have never cleaned of replaced the liner. Is this my problem? I don't use this welder that much.


Cleanliness is important when it comes to Mig welding. Any rust, dirt, dust, oil is liable to be deposited in the whip liner. If it's just a dirty liner you can try cleaning it with a solvent that doesn't leave an oil deposit (electric motor cleaner, brake cleaner, that sort of thing) compressed air and flexing of the whip.

Make sure your whip hasn't been crimped, if it has then no amount of cleaning will restore it to operation.. a new liner is the only reasonable answer.

It's possible that a bad tip can cause feed issues. Miller type tips are the worst, in my experience, sometimes you just get a tip that will weld to the wire when the current passes between them. I've worked in shops where I might go through three tips in five minutes and then hit one that would last all afternoon. If the wire sticks and you can hold the gun up and rotate your wrist and you feel a 'pop' and the wire jumps out of the tip then just change the tip out. Excessive roller pressure with a tip that's sticking to the wire can really make trouble for you. Nozzle dip is your friend sometimes with tip sticking issues.

Copper clad wire is not particularly friendly to liners, the copper is liable to flake off in the liner. I use bare wire, I bag the wire in a plastic bag on the feeder and I wrap a scratcher pad on the wire just before it goes into the feeder and I find that I have few feed issues. Wire that has even a trace of rust should be discarded as it will both fill your liner with rust and give poor quality welds.

I cant get it to cut. It starts a arc and then stops. I've changed the tip an electrode. what else should I do?


I didn't know you could cut with a mig? Do you mean weld? Is the wire feed moving freely? Is there a wire moving when you pull the trigger? Is it gas or just fluxed wire? You have to make sure the wire is grounded to the tip. Check the tip size against the wire.

Lincoln SP-135T Does nothing Please HELP


a mig welder must have a good ground to work, also dont try using rusty wire it will jam in the liner, have you checked you are getting wire feed from the neck? just pull the tright and with the welder on it should feed out, if you can stop it its to loos tighten up the pinch roller, is there power on this wire feed? i have often seen new welders strick up the weld with to slow a wire feed and to many amps running, what happens then is it burns the wire away in one flash, right up inside the welding tip and every thing comes to a grinding holt then???? it can and often will just weld the wire into the tip,, witch may mean a new tip is needed, take off the shroud and try to unscrewing the tip if no wire comes out when you pull the triger
as the wire is stuck or welded to it you may be able to get it out still??? but its best to fit a new one in, go one size bigger than the wire your using at first as you are sure to get it very hot??? untill you get the hang of welding,,, use a good gas mix like argon light it will weld stanless steel as well?? but co2 works well on miled steel only, the problem with co2 is its a cold gas and you need a lot more amps to weld the same thickness of steel use it at about 2 to 4 psi only indoors, out doors use it at 4 - 6 psi and if out doors keep out of the wind as much as you can or it will only blow the gas away from your weld if that happens you cant weld without gas being there as a sheeld, dont try using a no gas welder they are like the devel having a bad hair day to use,
even a good welder wont like one? there c*ap!!!!
only try welding clean steel not rusty steel or it will spit like mad at you and you wont get a good weld,
if at all,,one of the most common fults that is
but i bet you have weded the wire to your tip?
its so easy to do at first,,only two word of warning
keep well raped up, sparks well fly and were gloves',,,
and keep your head sheeld on well over your eyes dont ever ever look at the welder when welding it will burn your eyes realy bad and you will wake up in the night feling like some git has just pored sand into your eyes and its going to hert like hell for day's,,,
i find the solor head sheel is far better, its nearly clear when not welding and go's dark in milliseconds you will like them as you can see what you are doing right up till you strick up the ark then it go's dark,,
most welders last for years iv had mine for the last 35 years it a clark 150 turbo mig, and iv doged it to death too,,,
the only thing that could realy go wrong inside them is the rectifier, mains coil or a relay,, not much left in it to go wrong ,
and now iv bored to death good luck with your welding ,,i hope this has helped you out

I have a pro-mig 135 and while welding the arc surges up and down along with the wire feed.the feed is real jumpy and will not keep a constant smooth puddle


You need to clean and perhaps replace the liner in your wire feed gun. The liner gets tiny bits of dirt and **** up inside. After even normal use for a while, the liner itself gets worn away and makes the wire stick rather than smoothly poke into the puddle.

Liner maintenance time is also a good time to check the feed wheels for wear, look for the little ruts in the wheel to be dull or obviously worn at the edges. Wipe off the drive shafts and housing as long as you've got the drive wheels off anyway. :-)
All of this should have a nicely illustrated procedure in your user manual.

The other thing that can cause problems is that the welding wire can sometimes get rusty enough to be sticky inside the liner. Roll off a good length of wire (2 or 3 wraps around the spool) and inspect it for any sort of funkyness. If in doubt, blow out the liner, change the wire, and weld something to see if it works better.

Regards,
Carl
