I used the pulse feature on this machine, pretty nice.

I am still trying to translate generic terminology about pulse settings as described in general by Jody and how the controls are named on the alphatig.

Jody:

% on time (% ratio set)
Background current

On the alphatig 201xd:

Pulse time on (PTO)
Pulse amps (PA)
Pulse frequency (PF)
Main amps

I was trying to get a narrower lap-joint on some 1/8” steel and was welding at 105A, with 3/32” 2% lan and 1/16” filler, on the the following settings:

PTO-80%
PA-50
PF (7-30)

i think I like the upper range of the low, and lower range of the high, but don’t know why I like it.

Can someone PLEASE explain PTO and PO.
