pf> I've been trying for this since reading about it years ago.

This is the first I've heard about it.  At first I thought, "How do
you do plasma arc spray with a MIG machine?" But that's not what yer
talking about, is it?

pf> For 1/4" ( i assume single pass) they list 700 IPM , 280 to 350
pf> Amps,and 31 to 34 Volts!...035 wire
pf> HONK! deposition rate is 11#/hr.
pf> That must leave me with a duty cycle time of about 12 seconds!.

LBrown> How are you ever going to learn to troubleshoot and change
LBrown> parts if you pay attention to the duty cycle?

pf> Am already strong on involuntary educations, thanks.

Hah! :-) I'm with you, Pete.  One of the best parts of being employed
as a mechanic or millwright was that I could do *anything*.  Yo.  And
if it/I screwed up, the company had to eat it somehow. [1] With my own
gear, *I* have to eat it.  So before I tear something important apart,
something that I've never messed with before, I ask myself, "Am I
ready to scrap this and retain both my peace of mind and my financial
stability?"  If the answer is yes, then I'm good to go.  If the answer
is no, then I may get the willies trying, with excessive caution and
wasted time, to avoid "involuntary education".  Or maybe I'll just
procrastinate.

I don't think my CDN$750 Lincoln has the right gumpties to do "spray"
and I don't really want to create an artistic mound of smouldering
slag while finding out.

[1] Thinking back, AFAICR, I only did that once for an employer.  I
    was very clearly told, "While working here, you get one screwup
    like that for free. And that was the one."
