Esab argon arc converter. Converts your dc arc welder into HF start tig welder. Currently set to 240volt but can be set at 110v or lower voltages by changing connections on internal transformer. Connect dc arc welder and you have a ready to use tig welder. Solid piece of kit. I have used this many times and it works great. I’m selling many of my welding equipment as I no longer do welding jobs Please see other listings.
