I have a Lincoln Idealarc TIG 250/250. It's a big unit, not one of the
newer inverter types. I saw on the Lincoln web site that there is a
pulser unit available for the newer machines, model LINK 1619-1 for
about $360. My unit has the 6 pin amphenol connector for remote
control and was wondering if I could use it with the newer pulser
unit?

Simple answer, no.
The newer machines have pulsing ability built into the boards.
The controller just keys into this.
Older machines can't react fast enough to take advantage of a pulser,
or at least that is how it was explained to me by a experiences welder
reapir guy I know.

The earliest machines with built in pulsers were in the 70's, but they
weren't common until the 80's.

It would be simpler to build a timer circuit that runs inline with your
foot pedal.
