How much is the used argon arc welder now? How much is the cheapest argon arc welder? (welded stainless steel burglarproof window)
I am now using double use argon arc welding power with manual welding quality is also good, the price is not expensive suggest that you buy new or relatively new affordable
For your application, single phase 200A is enough, about 1000 new ones;Second-hand hard to say, depends on the specific circumstances. But I still suggest you buy a new one, reallink better, stable quality.
New less than 1000, second-hand reference. The key is power, 200A16V, 200A26 volts, and so on, maybe 16V or so
