However, further testing revealed that there is NO high frequency output. I checked the spark gap and it is about what it should be, which is .040. When HF is turned on, there is no arcing activity at all in the spark gap and no characteristic noise. I am, obviously, withdrawing my for sale offer until further notice. Any ideas will be appreciated. i I have a Lincoln TIG 300/300. I had no HF & it ended up being the relay. OK... I will look today with a printed manual in hand... Any sort of a relay should be easily replaceable. I will not presume too much from the beginning. i |
