[TheForge] tig setup

[Peter Fels And Phoebe Palmer]

Reis;
My old rinky-dink TIG was way before inverter units were on the 
market......sorry about being contrary.
Dave,
 Just enough to exclude the air ( argon is expensive). there are some 
variables .I set mine at about 15 cu/ft/hr to begin with....but i'm 
still pretty bad at it. Hold out for better advice!...........
Wonder if the Chinese offer a high freq stabilizer yet?
 Speaking of that, A friend got one of the Stryker hammers and tried to 
get it running right for almost a year with faint support. He finally 
video taped the hammer malfunctioning, noting each specific deficiency 
and posted it on the net as well as sending  a copy to Stryker.
It took that to get them to stand behind it..eventually. They sent him a 
new set of valves and  a guy came out and ground out the obstructions in 
the  internal air passages.
Anyang support is worse in my experience............Pete F
