Too much tension can cause wear on the wire and too little can lead to birdnesting, so it’s important to find the sweet spot on both parts. Your welding wire not feeding properly off the spool is likely due to incorrect tension on either the spool break, the drive rolls, or both. Once you’re in the habit, it will save you time and money in the long run. Maintaining your wire in between jobs is as easy as taking it out of the welder and putting it under a blanket or in a garbage bag. You’ll also need to either blow out or replace your liner (more on that later.) Any wire deformity can also cause issues in feeding. If you do see rust, you can try and unspool until you find clean wire. Moisture or disuse for long periods of time can cause rust, which in turn will clog up your liner. And because wire-feed issues can happen anywhere along the length of the gun, you may need to check several areas until you find the problem.įirst, take a look at the wire itself.

Speedway Series 125 Amp Flux Welder Manual Manualsbrain Copyright Make spot welds on the actual work piece at desired locations. Make practice spot welds on scrap metal, varying the length of time you hold the trigger, until a desired spot weld is made. Pull the trigger on the torch and release it when it appears that the desired penetra- tion has been achieved. Hold the nozzle piece completely perpen- dicular to and about 14 inch off the work piece. Select the wire diameter and heat setting recommended above for the method of spot welding you intend to use. The LAP SPOT METHOD directs the welding arc to penetrate the bottom and top pieces, at the same time, right along each side of the lap joint seam.
Select the wire diameter, heat setting, and tune in the wire speed as if you were welding the same thickness material with a continuous bead. In this method, a hole is punched or drilled into the top piece of metal and the arc is directed through the hole to pene- trate into the bottom piece. The PUNCH AND FILL METHOD pro- duces a weld with the most finished appearance of the three spot weld meth- ods. Wire diameters that tend to work best, with the burn-through method are 0.035 inch self-shielding flux-core wire.ĭo not use 0.030 inch self-shielding flux- core wires when using the burn-through method unless the metal is VERY thin or excessive filler metal build-up and mini- mal penetration is acceptable.Īlways select the HIGH heat setting with the burn-through method and tune in the wire speed prior to making a spot weld.
