Flux core welding guns11/6/2023 ![]() Back end with durable rigid strain relief and Miller direct plug and trigger leads connect to Miller wire feeders and machines and allow simple maintenance.Ultra heavy-duty steel monocoil power cables are highly resistant to kinking for exceptional wire feed in abusive environments.Trigger guard instead of full size heat shield allows access to tight spaces while protecting trigger from damage.Trigger is sealed from outside contaminants, simply replaced and absorbs less heat than a metal trigger for long-life, greater arc-on time and lower heat output.Centerfire contact tips are easy-to-use and high performing - they provide better arc starts, less spatter and more consistent welds - and also last up to three times longer than competitive brands.Heavy duty sleeved gooseneck - 6 inch X 60 degree.Miller direct plug back end & 15' cable length.The Dura-Flux gun with fixed power cable liner is capable of feeding 1/16 - 5/64 diameter welding wires. It comes standard with a Miller back end and is the direct replacement gun for the Miller® SuitCase™ 12 VS wire feeder. The FLX3515AM features 15 foot length with durable fixed power cable liner and trigger shield. The tubular electrode wire is supplied through a spool and guided by a welding gun to the weld joint. Fusion takes place when a welding arc is established between the flux-cored electrode and the base metals. Genuine Berndard™ FLX3515AM Dura-Flux™ Gun is a 350 amp flux-cored gun specifically designed for use with self-shielded welding wires. Flux-cored welding is an arc welding process that deposits filler material with a shielding flux in the weld puddle. Well, you might want to wait another moment to see him learn proper use of tools ….Bernard™ Dura-Flux™ Self Shielded FCAW Gun FLX3515AM Kevin says, “You really can teach an old dog new tricks.” While he’s off getting himself a treat, please give this video a “like.” On the back side, there was really no penetration, so he could probably turn the voltage up a little bit to go with the extra wire feed to burn the weld down in there better. Kevin says he could increased the wire feed. He very rarely uses flux core, but at least it gets the job done. “Not too bad,” he says, asking viewers to take into account that this is the first time he’s used flux core with this machine and in the last 3 – 4 years. He tack welds the metal on each end than runs a welding bead between them. It’s not perfect, but it looks OK at least enough that you can get some work done with it.” Then he points to where he went to 225 on the wire speed. Kevin shows the sample, where he started his test, where he went to 190 on the wire speed. Kevin welds for a bit, then turns up the wire feed a little.Īfter welding, he uses a wire brush and a chisel to remove any slag, although there is none to speak of. He gets a piece of scrap metal to run a few weldng beads on and see how it works. Kevin sets the starting voltage at 19 volts. There’s no need for pre-flow with flux core. The spot timer was on, so he turned it off. He doesn’t need any wire feed at the end, so he leaves it at 60. The highest inductance is 100%, so he makes inductance 50 percent. He leaves it on 2T for the trigger control. ![]() He pages down on the Everlast Lightning control screen, toggling down to flux core, no gas. To use this machine with flux core, Kevin needs to set it up. This makes the end of the MIG welding gun a little bit smaller, so it’s a little easier to get down into tight places. If you’re using flux core, you can just leave the nozzle off because you aren’t using gas – there’s no reason to have the nozzle to direct the gas if you’re not using any. You can turn the wire feed up to make it feed faster, but it comes out pretty fast. It does not have an auto feed or a wire jog button, so you can just pull the trigger. ![]() When you are using flux core, you have to change the ground cable from the positive terminal to the negative terminal to make the polarity correct so the flux core wire runs correctly.īefore you feed the wire through the MIG welding gun, always take off the nozzle and tip, then just pull the trigger on this machine. Flux core welding just seems messy, Kevin explains, as he feeds the welding wire into the welder’s drive roll. Kevin swore he’d never weld with flux core, but decided to give it a try on the Everlast Lightning MTS 275 multiprocess welder.
