Hi all,

I am considering this Rossi 3 in 1 tig/arc/plasma:

https://www.edisons.com.au/rossi-tig...achine-ct620is

It can't take a foot control, but I was wondering what the two pin socket on the front is for? Their generic manual has a diagram for another machine and refers to something similar as a 'high frequency start control' - but I don't know if this is the same thing.

All advice welcome. Excuse me if the answer is obvious - I'm not a welder, but I did do a TAFE course some years ago - no tig.

Greg.
