5 Stars
Have patience and this thing will surprise you.
First thing, I will give the advice I have. Trash the tips and buy Hobart tips. I had an awful time with wire sticking during aluminum. Hobart tips didn’t stick.Next, spray WD-40 on the aluminum to make sawing possible. The aluminum gums up saw teeth, so spray. Clean the aluminum to being spotless with a stainless brush.Buy a big bottle of argon. This welder eats the argon. Forget what you know about steel welding. Aluminum stays silver and will melt away or the underside will sag from too much heat. Use the horseshoe pattern while pushing the wire. Don’t fool around too long getting a weld. . The puddle is very hard to see, so plan on making a second pass for better penetration on structure welds. The chart shows suggested speed and temp. Start there and experiment. This spool gun took some modifications to keep the wire from getting out of track, but overall, it’s great. I bought a crashed aluminum bass boat and rebuilt it with this welder. The wire side for steel has a good penetration and I’m pleased. I used 4 lbs of aluminum through this. Two weeks ago I was contemplating returning it. Sticking wire cost me hours. Good tips made it really hum. I think my aluminum welds look fine. I’m not only keeping it, I’m advertising that I will weld aluminum to people. The local guy gets $150/hr for aluminum. I’m $120/hr.BTW, I learned the WD-40 thing on the last day of welding. I wasted 5 “Torch” Milwaukee sawzall blades prior.
