Inverters

Hi Cope........... You are correct as I recall Leif Lungstead brought the inverter technology with him when he cam over from Sweeden and did indeed work for POWCON.............. and I and Ian (who works for Arc Products now) worked for Leif with another gentlemen named Tony..........Enjoy.............Rock..............[email protected]

Thanks for the info. If I'm thinking right POW-CON invented the inverter technology and Miller purchased that technology and has signifigantly improved it. OKAY MR CAPS: ROCK PLEASE CORRECT ME IF I'M WRONG.

Hawk, that's basically correct. Miller had to sell off part of their operation after the ITW acquisition. PowCon has been resurrected as Arcon. Their 300 amp inverter Stick/Mig or Stick/Tig machines run $250 and up. If you get a chance to buy a PowCon reasonably, go for it. Parts and service are available from Arc-Products in San Diego.

There is a difference is smaw also, but it is marginal. Can somebody give me the scoop as to why? HAS ANYONE ELSE EXPERIENCED THIS?

Hawk, I have noticed that my PowCon runs much hotter in SMAW mode than my old Miller 250 amp AC machine, but since the PwoCon is DC, I don't have a direct comparison.

So will the Dynasty 200 comfortably do 1/4" aluminum w/100%argon? What is the max thickness for aluminum with 100% helium for this machine? Is thoriated tungsten acceptable for these applications or is ceriated tungsten a better choice?

HAWK...........Basically it all boils down to how fast we switch those IGBT'S in the inverters vs the 60 cycles per seconds of a transformer machine...............in a nut shell..........Rock...
