I have spent a little time playing with my new Dual Voltage 200DX Welder. I'm working on getting used to using the settings to weld mild steel and aluminum. I have been using a CK9 torch with Superflex Hose which is much easier for me to use on the small stuff. In addition, I have been using the foot pedal that was included with the welder purchase.
I have never used pulse before and was anxious to try it out on a corner joint on a couple of .075 in. steel strips. I set the Amperage to 65 Amps, Pulse Switch to low, Pulse Frequency to about 1 PPS, Pulse Amps to 30%, and Pulse Time On to 50%. I used my CK9 Torch with 1/16 in. E3 Tungsten. I tacked the strips together on the ends with filler rod. There was no filler rod used to run the bead down the corner joint. I was very happy with the results. Since I am new to TIG welding, I need all the help I can get and pulse really helped me get good results in this application. Oh yea, and did I mention I like the PowerTig 200DX so far?
