As I said in my introduction, I own an European version of PowerTig 250EX machine. First of all, I wanna say 'thank you' to Everlast distributor in Finland for quick delivery and support. I have tested the machine for aluminium and mild steel applications in TIG mode, and for mild steel in MMA mode. The welding processes can be fine adjusted (only pulse has 3 knobs), so I am very glad with the results, even so, all the tests were made in cold garage (-10*C or 14*F) with preheating of the welded parts. Here you can see an example of seam on mild steel pipes.
Also, I tried to weld copper and brass. Brass could be welded, but no more brass welding ever!!!
The only function I have no idea how to use is a spot timer, but I can live with that.
That standard cart seems to be flimsy on small wheels, so I did not order one. I've made my own cart from pipes using the very machine. It's already welded but not painted (I am waiting for warm weather). There are preliminary photos of the cart without front handle and other parts which are supposed to be bolted (wheels, loops, and plates).
There are some things I have to notice.
- The main has to be protected with C16 circuit breaker (slow protection). Usually, the kind of protection is used to protect an equipment with inductive load (powerful motors and etc), but even my lathe works well with B16 circuit breaker. And I am not telling about welding time; the B16 goes off just after the machine is switched on.
- The machine has a standard European plug (3P+N+E) with 5 pins, however only 4 of them are in use (neutral wire is not connected). I suppose it's because of so called triangle connection.
- The connectors for cooling liquid are the same as for argon, and the hoses are not even marked with red/blue.
- It is hard to get reading of current when pulse in LO position (the value seems to be random in some range).
Summary: I think it is a real bargain for the money, and it could be used to perform very good welding.
