Alphatig 200x TIG Welder #3- Welding Steel Sheet!

Haven't had much time to play lately.

Decided it was time to practice a little. Tried something different this time though- switched it over to DC to weld on some steel. With my old welder, this was NOT an easy process. It involved unplugging the high frequency box and taking leads out of it and then re-routing the leads to the correct lugs on the main welder. Might not sound like a big deal but trust me, it was a royal pain.

The Alphatig- Click two switches. Wow, that was easy...

I changed the AC to DC, and the pulse to direct / flat / whatever it's called.

This thing welds steel BEAUTIFULLY. I'm a sucky welder as you can tell, but I was astounded by how easy it was to kludge pieces together. I didn't burn ONE SINGLE HOLE through the 18g sheet I'm using here. Compare that to using my little 110 wire feed where I couldn't run a bead longer than 1/4" without having to stop and let the metal cool, this TIG welder is AWESOME!

First nasty welds, getting it figured out.

Once I understood I could actually put some heat to it and not blow holes the size of Texas, I made some progress. Top is a lap joint, middle is a butt joint, and the bottom is just a bead ran on top of the metal.

The lap joint turned out really nice. Was giving a little forward-back motion as I went and it seems to have worked great.

Time for a little project! This would have been impossible to make on my wire feed welder. Cut a bunch of 2" squares out and tacked them all together. I should also mention tacking things like this together was a breeze. LOVE having the foot pedal.

Not real pretty, but all welded up.

Wish I could spend some time practicing, 'cause I really need it. Got a couple of bigger projects in mind if I can ever get caught up on everything else!
