First check check tip is right size for wire or is unobstructed may just need a clean with tip cleaners.if this is happening while trying to change wire roll try removing the tip feeding the wire through then slide tip over wire.

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.

You may have the scew settint your wire tension set to tight. Try loosening the tension and if that doesnt work check the eletrical wire that supplies the power to the roller and make sure it hasnt become disconected.

SOURCE: my sp 135 welder is burning the wire

The wire will burn back between wherever it gets the power, to wherever it is grounded. If it burns back to the rollers, it must not be getting power at the contact tip.
Remember, if you are using a shielding gas, the gun wires up to the (+). If you are using flux core, the gun wires to the (-).
Of course the 'ground' connects to the opposite.
Sounds like the drive rollers are shorted to 'ground'.

Its stuck in 1st ,when back tire is off ground and clutch is engaged tire stops spinning. So it seems clutch is engaging but shift lever is stuck in place. Please help any info appreciated


Hi, sometimes the wire gets stuck when feeding through at the lip on the welding electrode tip. Try unscrewing the welding tip on the end of the welding hand piece to make sure the wire is not getting stuck there. If the wire come through with the tip removed, then screw the tip back on over the wire. Withdraw the wire and then see if the wire will initially feed through a meter or two untill it hits the welding tip.

While welding with SP 100 wire feed. Wire gets stuck inside cord and have to use pliers to pull it out. It gets stuck quite often. Not sure if the cord is shorting out on the inside.


Hi,
Turn the wire feed speed up just a bit faster... the wire is coming out too slow and burning back into the tip.

I HAVE A LINCOLN 175 MIG WELDER THAT WHEN I GROUND IT AND PULL THE TRIGGER THE WIRE GETS RED HOT AND BREAKS AT THE FEEDER. I DON'T KNOW WHAT THE PROBLEM IS.


Hello, do you have the welding tip in the nozzle? This tip provides the proper grounding of the electrode wire.

Have a Hobart Beta-Mig 170 Wire will not feed


First make sure the nozzle tip is free of any debris and the wire will slide easily. Lift the case and go to the wire feed unit. Loosen the pressure nob then lift up to release the pressure wheel. Make sure the bottom wheel ( should have two grooves, one for .35 wire and the other for 025 wire.) Make sure the Wire Feed Tip is also free and it allows the wire to pass through. Pass the wire through the feeder across the drive wheel and into the hose. Allow the pressure wheel to drop, then lift the pressure know to the upright position. Turn clockwise to put tension on the wheel. Make sure the gas is OFF, turn power on, depress trigger switch. This should allow the wheel to turn and feed the wire.

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.

    Mig replace tip


    Pull off the extreme outer nozzle of the MIG gun. Clean the inside of this nozzle with MIG pliers or round wire brush. Unscrew the welding tip. (If it is stuck, try using a pair of pliers lightly). Clean the entire area with a regular wire brush. Screw on the new tip finger tight, but snug. Replace the outer nozzle.

    Mig Question


    MIG stands for Metal Inert Gas welding, many times called Wire-feed.. Also referred as GMAW (Gas Metal Arc Welding). The "Metal" refers to the wire which is what is used to start the arc. It is shielded by inert gas and the feeding wire also acts as the filler rod. A semi-automatic process, it is fairly easy to learn and use.
