    Seems ok, dual voltage so you can run low hydrogen, (use the high setting more most things), duty cycle will be fine for general use.
    One question, how good is your power supply? If you are running this off 240v then it will eat power at it's higher settings, (I dispute their 20A powerpoint claim as I have done this with a similar welder). Perhaps, if you have not already, consider an inverter power source. They are not the be all and end all, but are another option.

    i just want the option of been able to burn 4mm rods and not tripping the power after 30 seconds, as for power supply, im sure the 20 ampre plug wil be fine, just need to change the 15 breaker and gpo to 20s. spoke with my neighbour who's a sparky and he says its not a problem.

    the main thing is: not wanting to make the buy purely based on the 250A and thats its red, need to know if anyone out there has used one, knows of anyone who has one and how reliable it is. will it become a door stop after a days welding? if so i can use my old welder for that already.
    thanks.

    End of the day, not much can go wrong with this type of welder. Other than the windings overheating and failing there are few areas for failure and it does have a 10 year warranty. A big plus is the use of copper windings.
    Not to labour the point, but I do not believe that you will run that welder off a 20A circuit breaker at anything near maximum current for very long. I have a 220A Peerless and running it off 20A fuse wire I found I would have to replace the fuse wire monthly as it had been carrying so mujch current that it had heated up and oxidised. Welders produce surge current loads far in excess of their rated current draw and my experience with circuit breakers has been that they do not handle these as well as fuse wire of the same amperage.
    My guess is that you will not be welding at 250A very much anyway, although if you were to run 4mm electrodes at 170A on the high voltage setting, you would be getting up there as far as current draw goes.
