I have a Lincoln HI-FREQ TIG arc starter that I would like to sell. I have used this over the years with buzz box type welder, and welder gen. for add on TIG. It is in good working condition. $275 or trades + shipping. The regulator / flow gage is included but will need repaired. I just sold the welder this was on and no longer need this. Also have a voltage seensing wire feeder that I might sell if your interested.
