Mig Welding Basics: Mig Wire Installation

You mig welding wire installation is actually very simple. The first step is to make sure you use a mig welding wire is very high quality. Why? You can have so many problems with mig welding wire does not eat, burn again, excess spatter, birds nesting and so forth.

Assuming there are no long spool of wire mig in mig welder. The first think you have to do to physically open the case welding machine or wire feed up.

Then you have to remove a peg or large plastic nut that is attached to the hub or axle will slide into the welding wire. Now open the box mig wire, check that it is the correct wire size you wish to use and the proper type of wire. Also gives a glimpse and check out the rust.

Lift and slide the spool to the axle / hub. Replace the pegs or plastic nut.

Now go to the end of mig welding gun and remove nozzle / shroud. This will either make or screw off depending on the brand blowtorch. At that time, remove the contact tip by unscrewing it with pliers.

Set beside the nozzle and contact tip.

Back to the mig wire, and in between the coils of wire and mig welding torch which attaches to the front of the machine or remote wire feeder you will find the feed roller or rollers drive.

There will be a kind of hook that can be turned open. This action will increase the feed rollers and allows you to feed wire to the coil drive.

Note that the feed rollers there are usually two grooves. The wire needs to sit in one groove. On the side of the feed rollers will hit the mark that shows what size wire to use in which the groove.

Mig welding machine normally comes with two different sized grooves. For example, 0.9mm and 1.2mm is 0.035 "and 0.045".

Make sure that the diameter of mig welding wire suitable sized garden right on the feed rollers. When running a welding wire precision you need to use the correct path for the feed rollers with a diameter sized mig wire correctly.

You can get away with using slightly different sized feed rollers when you run the wire cheapie low quality mig. Why is this? This is because the wire diameter tolerance will go up and down. So the wire will get thicker and thinner all the time that would compensate for the slightly wrong-sized feed rollers.

I do not recommend this to anyone who is serious about making money in a production environment or welding and fabrication business. This will cause many difficulties.

Now you have to be careful and I emphasize carefully find the end of mig wire and hold onto it and do not let go. If you do it will spin, spin, spin, and you will have a big mess of wire mig in all places.

With the end of mig wire feed to the roller driver, you'll have to go through the small feed tube. This helps guide the wire over the feed rollers.

Keep feeding the wire through the coil driver of the past and into the beginning of mig welding gun. Feed it through about a foot or more.

Lowering and locking latches to drive the rollers, and adjust to get back to number one or the lightest possible setting. Then screw / adjust the voltage down a bit.

Furthermore, if you're using gas, turn the bottle to store your expensive welding gas lay you welding gun and cable out straight from the welder and pull the trigger. Wire will slowly eat through the liner and pop out on the tip holder. You can boost the speed of the feed adjuster to get the wire through more quickly.

Now when the wire ends of the tubes appeared to put the contact or contacts again. Put the nozzle back and cut the wire for about half an inch sticking out.

You are almost done now. You change the gas again. Now ideally you want to feed the wire tension mechanism to be as light as possible so as not to damage the form of welding wire. Welding deformation of premature wear will occur on the feed rollers simply because too much power. This will cause irregular wear in the contact tip and the weld wire will have a small bit of material sheared and squeezed it to be down to the ship from the torch, and from time to time causing it to build up internal resistance which will cause more problems on the track welding.
