Hey, I would like some opinions about if I should be purchasing a brand new Miller syncrowave 250 DX or a Lincoln precision TIG 275 package. Up here in canada the pricing is very competitive between the two, and if one is substantially better than the other, then the pricing should reflect. But it does'nt reflect in the price. I am purchasing it for specialty welding and also production for Aluminum, Stainless, and regular Steel
I have seen a sync 250 dx in working form, as well as a sync 350. I have access to a 350 near my home, and a friend has a 250. Both I have seen weld with no problems at all. But the sync 350 had a start amperage circuit board problem, and has the board fixed. I've never seen a Lincoln 275 in working form, but have heard they have no problems as well. I have heard nothing but good things about the miller machines listed, accept one person says that claims to be some guru in welding saying the sync 250's are pieces of crap, and has seen them fail repeatedly. Apparently the 250 can't live up to their advertized material thickness welding capabilities. This "guru" says the 250 can weld 1/4" thick aluminum from the edge, but cant weld 1/4" thick along the center of the plate from cold.This guru also states that Lincoln is the only welder for TIG that should be used.
I've done my research on each manufacturers websites:
But only Miller states material thickness limitations, and it says 3/8" Aluminum capabilities. What can Lincoln weld thickness up to? I know it takes alot of amperage to weld aluminum in AC, so I have 575V 3PH AC in my establishment to supply what ever amperage the machine wants.
I know if I am to pre-heat material, I can weld thicker materials than 3/8" Aluminum, but what I would need to know is if the sync 250 can live up to welding a cold 1/4 or 3/8" aluminum plate starting from the center of the plate and T-Weld another 1/4 or 3/8" plate to it without preheating..
I know to everyone price maters for making a choice to purchase. But personaly I have my limitations and they arn't very high. I know between $5k and $6k can get me either lincoln 275 or miller 250 but I need some advice about if this guru person's advice is true, or if he is just some Miller hater... I see manufacturer haters all the time, and I would rather not be swayed by one person's opinion....
So what do you think?
