Hi,
I just found this forum.
I have an older Airco machine from a Tech.School. It weighs about a half a ton.
I am looking for a manual for it.
Model 2.5A DDR 224 HFB
250 Amp. In addition to stick welding, It has a high frequency switch, plug-in, and timer with built in gas and water lines.
It's an oldie but a goodie.
I haven't tig welded for 40 years so I need to re-learn it.
Thanks for any help.
