Question about Garden

1 Answer

When welding, the wire drive motor seems to bind up after 3 or 4 revolutions on the sporcket. I took the end off of the gun and pressed the trigger and the wire fed easily for a few secs and just stopped. Changed out the sprocket but the problem seems to be coming from the internal part of machine

Could be the drive motor is going out, or overheating. Or the spool is too tight. If you can get to the motor wiring check the AC with a clamp-on meter to see how much it's pulling. If you're lucky the label on the motor will tell you what the normal draw is.. that small a motor it should be pretty low. If you hold down the trigger even after the wire stops, does the motor start to get hot? Can you turn the spool (lightly) by hand to see if that's hung up and hanging the motor?

Good luck!

I have a kende mig 105 gasless welder,but the wire isn't getting fed through on the feed wheel,tried different welding wire and also turned the wheel,tried tightening the wheel,slackening it as well,i


Here's a few things you can check:
When gun trigger is pulled, do the drive wheels turn? If they aren't, pull the trigger again; do you hear anything within the machine (contactors closing, gas solinouds opening, any clicking, etc.) that would indicate the trigger circuit is functional?
If the drive wheels are turning, but wire isn't being pushed thru the mig gun, check for proper drive roll vs. wire size. If that is correct, check gun liner for obstructions. Flux cored wire tends to stop up a wire liner fairly quickly.

Why does my lincoln 140c cut out?


Had the same issue with a friends SP125
Just got to looking at the Welder. Here's what I found. Yes, the Drive motor would thermally shutdown even if I holding the trigger and not welding. Ends up that there thermo sensor is not too sensitive, it ends up that the two pointed nodes on ether side of the Drive wheel were gummed up. A simple loosening of a screw to get them out. Cleaned them with Brake Cleaner and a paper clip and it took all the restrictions out. When trying to pull the Wire out of the Gun it too was tough to get out. Added some mineral spirits to that ( figured Brake cleaner was too aggressive) and it helped a lot. Working good now.

Lincon mig stops feeding wire


Been welding for a while, open side, check for proper tension on the feed wheel inside side panel, hit the trigger, if feed motor continues to spin tensioner needs tightened or mig wire may be getting hung up inside main cable lead. If motor is off on off on then its probbably the switch on the trigger getting a bad good connection, hope this helps o and check welding tip on gun end, may need replaced if worn or melted, unscrews.

I have a Linde 160 MIG and it will not feed wire, seems to be motor not gun. . . Thanks


Just to make sure it is not the trigger switch, unplug the gun from the connector. With a clip try to bridge up the connector, if the motor does not turn then your gun trigger it's fine.

A new motor can be order it at any of your local welding stores. Try Praxair.

If this was useful to you please vote. thanks..

I have a lincoln sp-175plus, when trying to weld it the arc just melts the wire and it balls up at the end. I also put a new contact tip in. As well sometimes the wire feed just stops. I then press...


Your drive tension is too light. There are rollers that the wire feeds through and they need to be tightened. They should push the wire through the gun but slip if you put the tip against a solid object and pull the trigger. If they do not slip, they will jam your gun. Give the tensioner another turn.

Pull triger the welder wouln't start and the wire dozn't feed


You could have a couple of things wrong. A bad trigger switch is very common. That is about 99% of the time. Next are connections to the box.Not too common but they can corrode or get loose. Then you can have drive motor issues or something annoying like a pinched or galled liner stopping the wire.

To rule out most things we need to know if the wire feeder is working or trying to. All we need to do is press the trigger and listen for the feeder motor. We want to do this with the top open so we can see it as well. If it doesn't do anything then we need to look at the switch, connections or the motor itself.

If it sounds/looks like it wants to work then we might have something simple like the wire drive or pickup being out of adjustment or worn or the wrong size or type for the wire you are using. If you lay the lines out straight and then try to manually move the wire it should be stiff but smooth. Use pliers at the pistol to pull on the wire, and loosen off the driver wheel tension. If the liner has a kink or was damaged then the wire will not feed or will be very hard to move.

My bet would be on the switch.

Welding gun doesnt respond when trigger is pressed


First determine if the wire drive motor responds to the trigger.

If not, then there is a fuse for the motor I believe.

If the motor tries to drive the wire, the wire MAY have jammed into the side of the transfer tube or the end fitting preventing it from moving.

When I press on the welding gun trigger the wire spool clicks but the wire won't feed. It's not the wire speed, spool doesn't seem to be stuck. No melted wire on tip. You can pull the wire through the gun...


Sounds like the wire driver circuit, or drive or motor is faulty. Probably a blow driver transistor or chip. But may be a motor brushes if it has any?

Lincoln 3200hd. welder,when power switch turns on, the fan comes on, but when i pull the trigger on gun to start to weld nothing happens the wire does not feed. i am not sure what is happening


open the area were the role of wire is and check when trigger pulled if any action to feed motor. [wire might be stuck at end, or there usually is a small fuse in that area for feed motor]
