I overheated the TWECO torch on my TIG (20+ yr. old Miller Synchrowave 250) enough to deform the plastic sheath, most likely due to poor water circulation through the torch. With the sheath slid back, there is no real damage, the hoses and connections appear o.k., so I think the torch is still ok.
The pump has always seemed to be weak, and I don't have a good sense of how much water it should pump or how to test it. I visited the local welding supply (Airgas in Salinas), and nobody there was familiar with water cooled torches or replacement pumps, although I can't say I am surprised. That shop used to be a Victor shop, then Airco, now Airgas, and the level of knowledge has gone down and down and down. I guess all the TIG units they sell don't come with water cooled torches???
Here is a photo of the water cooling unit, which has no name on it, so if you recognize it please advise. When the TIG welder is on, water flows into the jar in the foreground, which drains into the tank, but the flow is pretty small.
Thanks for any help in locating repair parts for the pump...
