PowerTig250EX Torch Control

[JJW]

I have a Torch mounted hand controls I sometimes use with my current TIG torch.
It's a "CK Worlwide" Amptrak torch control: it's a contact switch and a 1000 ohms control slider with a 14 pin connector for TIG torch hand control' {it's for old Thermal Arc TIG welders}.
I am fairly handy, so I can make up adapter cables to go from the 14 pin connectors to a 7 pin connector, if I can get the 7 pin connectors.

I have a few PowerTig 250EX questions.
What ohms are the remote amperage controller?

What is the availability of extra 7 Pin connectors for the Torch Control hook-up on the front panel?

Is there any availability of strap on TIG torch contact switches?

Thanks in Advance,
John
