When I looked on the web for information about how to set up and use TIG pulse, I found a surprising lack of information, including on the manufacturer's sites. The manufacturers promote pulse as a selling point, but don't give you a lot of information to tell you how to use it.I recently upgraded to a Synchrowave 200 TIG welder. It has a pulse feature, which I understand can be beneficial on thin sheet metal. I weld quite a bit of 0.040 inch (1mm) copper, which is hard to weld, and I need all the help that I can get. (If you don't weld copper, it is like aluminum, but more difficult because more conductive. You use DC instead of AC). I have been playing with it, slowing down the pulse below 1 pulse per second, adjusting the pulse cycle to 33%, etc. It seems to work in terms of good penetration without burn through, but the weld comes out pretty lumpy, no surprise there. I probably need to speed up the pulse to maybe 1.5 pulses per second to get a more normal looking weld. The problem is that there are three pulse parameters, pulse frequency, pulse duty cycle, and the background current percentage, plus the current setting and the foot pedal, so hard to know which number to tweak in which direction.I am looking for any information about using TIG pulse, especially related to thin metal.RichardLast edited by raferguson; 09-24-2009 at 09:34 PM.
