Hey all,
I'm new to TIG but have a TB250G that I use mostly as a power source to MIG and with a spoolmatic for aluminum. When I bought the TB250G the seller gave me several TIG torches and tungstens. I also came by a HF-250 with a cable that goes from the 5 pin connector on the HF-250 to the 14 pin on the Trailblazer. When I use the foot pedal with the HF I get gas flow but no weld current. Am I missing a piece of the puzzle? Thanks in advance, D. LaBounty, Sumter S.C.
