ok, but this fellow is a aero space wellder contracted by nasa and the marshal space flight center... and also doing contract work for the army and various other contracts... you may not have made my choice... fair e enough,, but lite speed what so prefunctory with me that i did not feel good at all with giving them a thou to fix the problem.... i trust the college instructor, contractor, and man who has 50 years exp... more then some guy i send the problem to and hope he gets it right... i talked with the man... for a good hour or 2 to see where his head was at... seems solid showed me his 6/4 welding rods has VAST experience in 6/4 tig,, but usually builds a box for the purge process with his other work.. explained to me the whole process. purge argon throught the tubes and wants to do a 2 pass weld .. was referred to me by a specialty welding supply house as the only guy in the state that they would trust for the task.... in short... i did about as much research as i could before making the decision... what it right? i dont know.... but i dont think i could find a more capable craftsman other then litespeed and i did not get a good vibe at all from them.
dunno...
