Greetings,
I've seen the videos of tig welding razor blades, thin sheet, coke cans, etc. and in every instance where the ppm is mentioned the range is from about 30 to 150. So what circumstances would require the ppm of 200 to 500 that some of these machines are designed to produce?
Also, the pulse frequency spec. is shown as .5-20hz. or .2-500hz., why not .5-20ppm or .2-500ppm.? Am I reading it wrong?
Thanks, Richard
