You are talking about the 2 white wires that come out of the gun and conect to the welder right? You are also talking about the wire that runs off the spool though the gun? Well if not this will not help you but if you are then it is the solution. The gun slides through the hole in front of the welder. inside there is a butterfly screw that needs to be loosend to allow the gun end to go in all the way. you tighten the screw back down after (welding whip) gun is installed. after that if you look inside the welder at where you just did the work to slide the gun in. You will look above the whip and see two prongs that are sticking out to allow the 2 wires to slip onto the conection. It should not matter which wire goes on which tab but both have to be connected. After that then turn on the welder and squeeze the triger for a second and the wheels on the inside of the welder should start turning. Now shut off the welder and unplug it. After you install the spool you will notice two rollers. Well on the left hand side of the rollers you will see a kind of handle / nut at the top. you should loosen the nut a few turns and be able to slide it to the left until it pivots down and out of the way. now you should be able to pivot toe top roller up enough to get the wire in there. Take your wire and carefully run the wire through the rollers and into the gun. Only put in about 6 inches or so of the wire. Now you lay the top roller back down and make sure that the wire is in the groove of the roller. After that is dont then pivot that retaining bolt back up to hold down the top roller. If it feels like a hard thing to do then loosen the bolt cap a little bit more to allow for the wire size. Now tighten the retainins screw just a little bit once you put it back into original position. After this make sure that you do not have a welding tip or nozzel on the trigger side of the gun. Now plug back in and then turn welder back on. keep the welder whip as strait as possible.Extended from the machine with zero loops in it. it is alright to bring it back to the side of the machine so as you can see what you are doing. Now squeez the trigger and the rollers should start moving. If the wire roll is not feeding wire into the gun then that nut that holds the roller down needs to be tightened up just a touch. Sqeez the trigger again and see if it despences the wire. if it does not then tighten and repeat until it does. DO NOT OVERTIGHTEN! That will flatten or crush the wire wich will wear out your internal gun and you rollers. Use the least amount of presure that you can to get the wire to spool into the gun. Well that should do it. If that is not the solution you are looking for then let me know and I will see what else I can come up with...Good luck....keefers

Brand new Lincoln pro-mig140 will not arc at all what can the problem

all wiring connected inside by the wire reel, like where the power comes into that area so you can reverse the polarity. is the machine powering up? Lights on front, fan running etc? wire moving through liner? Check your ground clamp wire, make sure the liner is making contact inside the gun tip. Check plug wiring on both the welder and the socket, makes sure they are both wired correctly as well as tightened down securely/ I've seen plugs that were new from factory but had 1 wire not connected to a post, cut too short and just left it.
also check that the outlet is wired the same as the plug on the machine. they need to have the 2 hot wires correct you'll see red, black, white & green. red & black are hot and need to go to the red and black from the wall.

Why won't my welder turn on?

Hi Jessica:
Right off, I get worried when untrained people start re-wiring. Please, PLEASE, don't try re-wiring as a learn-as-you-go project. Electricity BITES!!!!
Here's some basic starting info, but it's not intended as instructions for you to follow.
- 110 usually powers the lights so you've got 1/2 of the 220 working.
- 110 will be between the black (or red) and white.
- 220 will be between the black and the red.
- the white is called Neutral
- the green is Ground and is necessary for SAFETY
There should be some wiring instructions with your welder.
Hope this helps.

I just need to know what my sp250 idlearc lincoln mig welder is single phase or three phase, my gurage has three phase running in how do i wire in ,if single phase


Your Machine is single phase, and it could be a 208/230V or a 230/460/575V depending on the model. Check what kind of voltage do you have at your garage first, before attempting to do the following:

On a three phase wiring you will have 4 wires with the following colors; green, red, white and black. If you have 208/220/230 volts available at your garage you can connect the green, white and black wires, always green being the ground cable in the middle, black and white don't matter which side you screw them in.

Before attempting to connect a 480V to the machine check machine's plaque information in the front (or back) for real voltage, because this voltage can burn the PC board of you machine. The same color sequence applies to the 480V.

Good luck.

The welder fan is running and when i push triger air flows but wire motor does not run

Check the heat resistor which is located on the circuit board behind the wire speed dial! Looks like a white oblong component and tends to desolder itself through heat on the board! Resolder it back in and it should work again!

I need to know how to wire in a new switch

Almost all saws built in the past 25 years or so will have a "plug and play " switch set up IE remove the old one and install the new one - pretty simple

If you are adding a "not from the factory switch" it simply needs to go in the hot ( black) wire white wire is Neutral and needs to be carried through Green is ground

Do you have a wiring diagram for a 50 amp male plug using 6-3 wire?

The configuration of the plug may vary by design but the way it is wired is the same no matter the plug configuration. Using 6/3 wire with no neutral white wire you simply connect the the Green ground to the ground on the male plug and the black and red wires to the other two plugs. Does not matter which. The is a 3 prong male plug. If you are using 6/3 with ground then connect the ground to the green ground plug, the white the direct opposite side as the ground and the red & black to the X & Y plugs, either one. This is a 4 prong male plug. If you are using a NEMA locking plug the lug that is bent is the ground. Connect the green ground wire there and the two other wires to the other lugs. Does not matter which one as each is carrying 120 volts. Look at the photo below. The plug on the left is a typical 3 prong plug. Notice the ground is connected to the top U shaped ground connection. The remaining 2 hots are connected to the two other lugs. On the right you see a 4 prong plug. You have the extra lug for the neutral. 9e28e8d.png

My welder just stopped welding. It's a Telwin 220 Mig. The fan is still running but there is no noise from the welder and the wire is not feeding. I had only used it for around 30 seconds before it...

your feeder may need adjusting or more commonly the tip has tacked itself on the edn cap
keep the line as straight as you can & keep feeder compartment clean!
keep plyers handy for when wire is stuck in the tip
if you need to replace wire spool or a brakage of the wire make sure the wire is free or BURRS b4 you put it in the tube or you will damage the tube!
