Aluminium welding - what I am doing wrong - beginner

admin

Hi everyone, I hope this is the right place to ask a question about my welding projects.I am a beginner and I would like to use my new welder for small home projects.I am having issues welding aluminum.Looks like the weld is not connected to the material. It is easy to break it. Welder: Hobart 210MVPVoltage: 115VSettings: 7/70 as chart saysSpoolrunner 100 spoolgunWire: 0.030 ER4043Gas: 100% Argon 30CFHWelding material: square 1/8 thick 6063T52

Reply:It is my opinion that you are never going to be successful welding aluminum with that machine on 115 volts. Your wall outlet has to deliver a full 20 amps to get the max output on 115 volts (actually it is 120v in the US, but whatever). If you are using a standard 15 amp outlet, you are already handicapped. Second, that machine is really a 90 amp machine on 120 volts (90 amps @20% duty cycle). You need a minimum of 120-130 amps to weld 1/8th inch material, maybe more. at 120 amps that machine has a 5% duty cycle or less. Finally, in looking at the volt amp curve, even if you get enough amps out of that machine, you likely are not going to get enough volts to achieve the required spray transfer (as least on 120volts).Plug it into a 240 volt outlet and I'll bet you will see a world of difference. You will be MUCH happier.Miller Multimatic 255
