    Default Unimig or Bossweld stick machine

    Hi all, I'm sure this kind of thing gets asked a lot so I'll do my best to keep it brief.


    I'm looking for a basic DC tig/stick welder that will run on a 10A plug. Narrowed it down to a few options and want to know which one you would go for if given the choice.

    Unimig Razorweld 140
    Duty cycle @ 140: stick 15%, tig 35%
    3 year warranty

    Bossweld Evo 140
    Duty cycle @ 140: stick 15%, tig 40%
    1 year warranty
    https://www.toolswarehouse.com.au/bo...nverter-welder


    Had a look at the Lincoln powercraft 130A too, but I think I'm more inclined to go with the above.


    Hoping to work with up to 5-6mm plate if possible (multiple passes/v-groove is fine)

    Any comments are appreciated, thanks.

    The warranty says it all from company to company one that is willing to flog a product with the bare minimum warranty to one that will compete with other manufacturers within the industry of upper class machines says a lot

    all though i like the look of the Bossweld welder with the digital read out, usually 12 months warranty will last 12 months 1 day than it will fail always happens

    when u get 3 years warranty this gives u enough time to master ARC and DC TIG than u can either on sell with the left over warranty (highly sort after) and upgrade or keep it longer knowing if it does malfunction your covered

    about 5 years ago i wanted to get into DC TIG but machines were not cheap like they are today so i was looking around and i found a cheap welder like your looking for on Gumtree it was advertised as second hand but later on inspection it was brand new and i was told the owner bought it tried it and could never work out how to TIG weld so lost interest within 20mins of using it so practically a brand new machine for me

    i was quiet happy with it i still have it today out in the shed it has advanced my TIG welding skills much more than were i was at, i never used the stick or ARC feature because i cannot stick weld for the life of me however buying this little machine i later realized when i messed up one job and that was a powerhead on a outboard i was trying to remove seized salt water snapped bolts from a aluminium block the problem was it was a cheap welder and the TIG feature like the stick welding had to be scratched to initiate the arc now these cheap basic welders don't arc to well they usually stick and grab the work piece than your fighting to get it to release its a bit of a tussle so in saying this try broaden your purchase range and look for a model that specifically states it arc's easy or something along those lines because when your learning the easier it is to start the arc the less of you will be and you'll get the hang of it like ABC

    forgot to add to help with the sticking u can turn up the amps but if sticking persist u have a cheaper made machine

    have u looked at Everlast Welders? they are not cheap but i am yet to read one bad story about there welders

    I've got 2 UniMig welders, so I'd be inclined to go with that Razorweld, although not because of it's UniMig per se, but if you look at the unit, it also has "Jasic" on it, which is the OEM manufacturer, who do have a good reputation for machines. UniMig also sell cheaper machines that don't have Jasic branding, suggesting they're sourced from some random Chinese factory, and I wouldn't have the same level of trust.

    That said, all those little inverter stick welders seem to perform surprisingly well.

    That little Unimig Razorweld 140 is underestimated i bought the 180 version today i thought i had absolutely no stick welding skills within 5mins i ran some beads within 40mins of opening the box i was laying down an ok weld, this little machine done around 10 welds each weld around 8-9cm over 40mins never hit the duty cycle but it eats those 2.5mm rods like crazy!

    what i liked about this welder is it has 4 meters of earth cable and 4 meters of torch cable so u can be 7-8 meters rom the ground clamp don't need to keep dragging it around

    its very quiet but only down side the 180 has 15amp plug i needed to run my shorted 15amp extension lead, good little welder tho one dial and away u go took me 2mins to set up

    i got mine from National Welding a walk in purchase they have the 180 on there site for $325 but $330 in store i picked up a box of there 6012 electrodes made by Gemini or $15, 2.5kg

    one last thing i was running mine around 55-60amps and as soon as the arc initiated the machines fan went quieter i don't know if this is how they are meant to work i hope its not a fault anyhow buy it
