Hello, Ive been looking at the PowerMaster 256, can anyone tell me what the open circut voltage is on this welder. It isnt on the spec sheet. I want to run 5p+ electrodes. And any other info would be handy to.

The arc force control will help run the 5P.
But if you are going to be running a lot of them, our PowerARC stick welders have a special 6010 function that burns them like nothing else I have ever seen in an inverter welder.
Tell me a little about your needs and what you will be doing so I can recommend the best unit for you.

Yeah ill be welding spool work. one of our procedures is 6010 root, hot pass. then low high cap. but we also use tig for stainless butts aswell.

Unless you NEED the plasma function, combined, for a commercial operation, I'd recommend the PowerTig 250EX and the PowerPlasma 50 or 60 as a separate unit.
The 250 EX will handle both processes just fine. The PowerArcs can be used with a gas valve torch to do the stainless if you'd like.
The 256 will do the job as well, but since it has a plasma cutter in it, it weighs about 25 lbs more and is difficult to move around when compared to the 250 EX.

Jumping in o this thread then. Can I assume that with the exception of the Plasma feature on the 256 the rest of the features are the same betweeen the 256 and the 250EX?? Looking at the web site this appears to be the case.

The 256 does not have the spot weld feature or the lift start feature. It has HF start only. The 250 EX has lift and HF start and spot weld feature.
