SOURCE: relay clicks, gas blows, rollers dont turn

If you use it regularly, the liner should be replaced about every 6 months. Make sure you get a wiper for the wire. It goes inside the machine, on the wire, just before the feed rollers. It keeps the dust from clogging the liner.

SOURCE: Toolex 140 mig welder, wont feed wire.

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: millermatic 200 won't weld

first check on the plate that tells imfo of unit ,there is what is called duty cycle.If the duty cycle says per say 30%,that means you can weld full power for 3 minuets before unit will shut down to cool.if it says 100% duty cycle there is no limit on weld time.this is the first thing to understand,if that is not the case check the main contactor where the power imput wires go,pull the gun trigger see if the contactor is pulling in , it should if not no welding amperage.

SOURCE: I have a hobart handler 120/90amp wire feed welder

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.

SOURCE: The wire feed on my welder will not work.

Maybe you can get lucky like I did . Some times the acr volt selector switch gets corrosion in it and wont let the circuit board know to send power to the wire feed motor. You can cycle this arc volt. switch in my case it is the a,b,c,d,e, switch back and fourth a few times and this will brake the corrosion and your wire might feed again as mine did . This corrosion build up happens from not using and or sollecting the switch much usually on a welder at hm that gets very little use. it is common good luck .

Lincoln hd100 weld pak mig welder wire nfeed motor not feeding wire


Presumably the wire feed motor is running and driving the wire feed roller?

If this is correct there are a few things to check - when welding it isn't unusual for the wire to become welded to the tip. When this happens a powerful wire feed tends to keep feeding until the wire becomes impossibly tangled and knotted. Low powered wire feed units usually just begin to slip on the wire especially when 0.8 mm or larger wire is being used.

Try removing the welding tip and check if clean new wire will feed smoothly; ensure the correct roller groove is being used for the size of wire.

A welder that is used infrequently often becomes troublesome for a while. Micro-rust forms on the outer layers of wire and some of it is removed as it travels through the torch liner, sometime the liner becomes damaged and should be replaced.

Removing the tip and wire and blowing trough both ends with compressed air should remove any accumulation of dirt and dust. Cut off and discard the outer layers of wire if they have become dull. I spray a little WD-40 on the wire to keep rust at bay and help the wire feed through the liner. Ensure the wire end is neat and straight and with the torch laid straight along the floor allow fresh, clean wire to feed through the liner.

Once a few inches of wire is protruding fit a new tip of the correct size, fit the gas shroud and you are good to go.
If the burn-back rate is adjustable on your machine it should be turned to minimum.

Various things can cause the wire to weld to the tip apart from the burn-back rate - dirty or corroded substrate, holding the welding torch too close to the work, incorrect adjustment of the power/current and wire speed and welding continuously so the tip becomes overheated and if gas is being used, a gas pressure/volume that is too low or perhaps attempting to weld in a draught...

Welding with CO2 gas produces a coarser operation with more spatter and suit some machines more than others. Some machines perform better and more consistently with Argoshield, a mix of CO2 and either 5% or 10% Argon. The added expense might be worth paying.

What size generator does it take to run an omnipro 220 multiprocess welding system


Best bet to check you buy a generator to run your welder safely is check the power rating on your welder. Welders need a good power source else they will not run properly.

I have a Lincoln wirematic 250 when I weld it will run fine but once in a while it will pulse the ark in the weld. And is doing it more often. Stoping me from running a continuous bead.


indicates the following problems
rusty wire in use-- the rust builds up in the inner wire and will not allow free movement
the inner cable is worn and is grabbing the wire in a groove -- the inner cable will wear a groove and that catches the wire in certain situations --
the feed rollers are worn or the wire in use is not correct for the groove in use
most feed rollers have 2 grooves and each one is for set dia wire there are different rollers if gasless wire is in use to prevent the wire from deforming as it passes through the rollers

the obvious, yet sometimes overlooked problem is to check if the wire feeder rollers.do you have the proper tension set?(did you do the wire test when you shot the wire to see if it bends or stops)

I have a weldmark 140. When you turn the voltage knob it controls the wire speed. The wire speed knob does nothing


Flip up the cover on the side to expose the welding wire rool.
push the feed button on your welding gun, and watch the feed rollers.
If they are turning, then you need to increase the force on your rollers untill the wire starts feeding.

If the rollers do not turn, then you most likely have a bad switch, or connection in your welding gun or your speed control

Good Luck

if motor and feeder roller is turning. check that their is the correct pressure on feeder roller for the wire thickness you are using and that it is in the right groove on those rollers.
also check the tip it may have splash buildup which is affecting the wire feed.
hope this helps
