    Default unimig jasic welders

    has anyone had any experience with these, you can get them as a black badged unimg box or for 400 cheaper you can get thesame welder in an orange box, im chasing a relatively portable welder for aluminium which means inverter and norstate gas recommended these,as a plus they also do mma and scratch tig

    Default Jasic TIG welders

    You're right, the orange box option is a lot cheaper than the black (they both have the"Jasic" name on them and appear identical) bought one last year on line and had it delivered to home near Wodonga, complete with foot remote control for $1185 from memory. To date I am very pleased with its performance on both DC (s/steel) and AC (aluminium) having done a range of work on both Al castings and sheet - boat hulls. A mate who is a welding inspector and pressure welder is also very impressed. Built a custom trolley for it and to date am very happy with its performance - the welder as well as the trolley! You mentioned scratch TIG, if fact these machines are hot start on AC! Your choice.
    hope this helps

    I'm by no means a pro and haven't used any other welder so can't compare but it seems to be doing the job. Also not sure which jasic you may be referring to as they do a fair range..

    Default Jasic models

    The model I bought was the 200 Amp AC/DC square wave TIG/stick

    I got a unimig from "tool specialist" cause they were cheeper , Mine is the 200 ac/dc same as yours and is identical to the jasic , last year boc were selling the same unit rebadged under one of their brands and it was dearer again but looked the same and the specs were identical

    I believe northerncat may be referring to the mig inverter machines by the way it is described mma ans scratch start tig.

    the mig inverters can mig aluminium just like a traditional transformer type machine.
    they can mma as well, and can scratch start tig on DC only, not AC as far as I know.

    if there is a downside, they cannot reach low amps on dc tig and do require a decent circuit to run off, I think the 250 inverter requires somewhere around about 32 amp rated circuit breaker (please all the electricians or those who think they understand electricity dont bite my head off about 32 amp circuit breaker 15 amp plug and cabling that may or may not be required to upgrade and licencing and standards and all that etc etc etc, im not an electrician and i dont pretend to be an electrician or offer any advice to anybody regarding electrical installations, just stating what i think is the case regarding this specific type of welder).

    Default Power supplies

    I think what you say is right. I draw from a dedicated circuit breaker rated at 32 amps I think, as you say - but I am not home to look at the moment. This in turn is part of a sub board that has 40 amps available. This machine and others kept tripping out a standard 15 amp circuit. Power supply is a bit like sheds, they're just never big enough! Three phase would be great - at a price, as my wife says "keep dreamin"

    I have a Jasic MIG 250 in the shed, I have managed to unpack it but as yet, I haven't had a chance to use it.
    It has a 15amp Plug & I have a 15amp socket on my switchboard but it only has a 16amp breaker on it.
    I'll let you know what happens.... soon I hope.

    Default power supplies still

    I will be keen to know how you get on Cliff, you should be able to run this up on spray transfer for thicker metal in the downhand position. I have also been running a WIA 205S MIG for 14 years, which at the time was about the highest amperage available in single phase. Runs well, but will not quite go to spray transfer running 0.9 mm wire using Argoshield light, a hotter gas may solve this, but for most of the light fabrication that I do the existing set up serves me well - mostly sheetmetal, purlin and SHS work up to 3 mm thick. I bought two WIA 250 single phase MIG's at the college where I work, these run beautifully in spray on 0.9 with Argo light, but are a much more expensive machine.
    Let me know how you get on when your machine is unpacked and up and running!
