    yes the gas is on the wire feeds thru the gun easy it just seems that there is no ground

    the handler 140 is the welder in question, it seems to make the normal click when the gun is depressed. the gas is on the fan is working, and the wire feeds perfect.

    as this is posted under the thread of a hobart handler 140 is this the welder you are having a problem with?

    I'm new to this forum and had not appreciated how it works yet

    do you have a make and model that would help?

    when the trigger switch on the welding torch is pressed and wire feed out of the torch, can you hear a "clunk" from the welder?

    I say a clunk rather than a click,

    A click would be the gas circuit energising

    A clunk would be the main power energising

    this does depend on make and model

    is the fan running

    does the wire feed

    does gas flow

Basic electricity, + and -, electricity needs a metallic path to follow, on the - side, start by inspecting the connection where the ground cable plugs into the machine. These connectors often wear out and sometimes they lose their connectivity. Wiggle it, feel it, visually inspect it, move on down the cable, are there any splices? I've seen them spliced in numerous places with black tape everywhere, and the owner's standing there scratching his head wondering... Check where the cable attaches the clamp, is it secure and tight? If you're satisfied the ground side is in good condition, then troubleshoot the +side. Now, how the torch side works is there are two electric paths that need to have connectivity. The first is a wire that connects inside the cover of the welder, runs all along the whip to the trigger, where it's connected to a switch (trigger), then follows back down the whip to the machine. If anything happens when you squeeze the trigger then this is all working properly, logical? If nothing happens, check the connections we just discussed. The other path is how the high voltage gets to your work. At the machine, connected to the wire drive is the liner of the whip. Where this is clamped to the drive is the connection, inspect it. then the electricity travels down the liner to the contact tip, which is how the electricity gets into the wire. If they put the electricity into the wire at the machine, the wire would be glowing red hot and melting all through the whip, because the resistance is the same as at the tip of the wire, get it? But the liner itself is heavier metal than the wire, so the resistance is less, so it doesn't heat in the liner, following? So if you pull the shield off the end of the handle, you'll see the contact tip that connects the + liner to the moving wire inside. Inspect it closely. If you still have no current flow after these inspections, there's still hope. Somewhere on the machine there should be two or more fuses. Find them and inspect them, if any are burnt, be sure to replace it with the same size and amp fuse. I'm sure that if you follow these steps, your welder will be working just fine before you know it. Please post back your results.

I have a120 MW snap-on welder that the wire feed works i accidentally touched to ground clamp sparked, and know nothing. is there a fuse or breaker??? the wire feed works still

Replace your contact tip on the end of the mig gun

Sounds like youve arced it out and the wire is stuck in the end of the contact tip but steel feeding possibly spitting wire out of the drive roll like we like to say birds nest

My mig welder will not make an arc

There is a small chance the transformer burned out, but more likely the switch has dirty contacts or burned out. If you turn the switch through all heat positions 2 or 3 times before you start welding in the morning, it should remedy it in the future. In the short term, spray some contact cleaner (or even WD 40 in this rare instance) into the heat selector switch and rotate it through the ranges a number of times to remove corrosion from contacts.

Will the wire arc when dragged across the ground clamp? If not- there are internal fuses in the machine and they may be loose or blown. There should be one in series with the "hot side" (the gun) of the circuit and sometimes on the ground clamp side of the circuit.

There is a small chance the transformer burned out, but more likely the switch has severely corroded or dirty contacts or the switch burned out.

I have a Hobart handler 120/90amp wire feed welder.When i try to weld,all i get is a small spark.I turn it off,turn it on and it does it again.The wire feed works good,it just sparks,but will not keep...

I have welded countless hours with Linde & Lincoln & even a few Hobarts & the only time that I ever had the same problem was when the ground connection either to the object I was welding, or the welding cable ground wasn't good & clean & tight. Same on stick welders also. I did develop the habit of grinding not only where I was preparing to weld, but where I was placing my ground clamp & that always provided a better "frying bacon" sound as I went along the business of pushing a bead. In a welder, the only other thing than that is involved is the step-up transformer and your wire. Hope this helps.

Welder Motor runs , Gen works , welder won't excite and weld

A MIG welder is a complicated machine, unlike the stick welder. You can lose a lot of time if you must wait for someone else to fix the MIG. If you know basic troubleshooting for your welding machines, you can save a lot of time and a lot of money.
See if the wire is feeding properly. A worn drive roller can affect the feed and cause it to slip. When you're checking, look for debris and dirt on the liner. This can also cause bird nesting. Sometimes troubleshooting welding machines is as simple as cleaning it and allowing the wire to move freely.
  • Step 2 Look at the tip near the wire exit, inside of the gun. A worn out tip doesn't allow the electricity to efficiently hit and creates a lot more work on the job. Burn back can cause a bad wire.
  • Step 3 Clean the welding cup of the splatter. This task seems mundane, but troubleshooting welding machines usually involves clean components. Proper gas coverage cannot occur if the cup is plugged.
  • Step 4 Inspect the ground clamp. When this part is coated with oxides, electrons can't readily transfer. A bad ground **** can cause a lot of resistance and change the way that the current comes back to the machine.
  • Step 5 Examine the welding cable for worn spots. A badly worn can cause problems.
  • Step 6 Adjust the brake on the wire spool. Setting it too high or too low can cause problems with your machine operation.
  • Sometimes you can overlook the simplest things when you're troubleshooting welding machines, so always go from the simple to the more complex.
  • Always have a qualified electrician look at the parts on the inside of the machine.
  • Don't continually subject your MIG welder to thermal overload, which could cause permanent damage.

    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
