Imig250p (pulse explained)

[Kempy]

Pulse welding aluminum with a spool gun with the I mig 250P or 205P using 75%/25% Helium Argon has any one tried it, I was thing of get the 250P or 205P if it works other welders with pulse are double pulse not single pulse like the Everlast Mig Pulse.

Is any one using a spool gun on aluminum using a I mig 205P in pulse mode and how well does it work look at buying one, sorrry the 250P does not have a spool gun connection. The gas can be Argon or Argon Helium mix.
The Everlast 205P works in single pulse and most of the welders that are on the market are double pulse. If not does it work well with the pulse off.
