    Default UNIMIG razor 200 ac/dc tig welder

    Hi All,
    Today I viewed the razor digital welder 200 ac/dc welder by Unimig.
    Does anyone have any opinions re this tig welder?

    Cheers

    I have the older version and it does really well.
    one of the guys at work has the new one and it is just as good but heaps smaller which is great for offsite work.
    I always use a pedal for tig and I’m not a huge fan of the unimig pedals. Big and heavy. The pedal used to be a $250 option. Not sure what it’s worth now.
    Lincon also have a nice looking Tig similar size and price. Haven’t used on though.

    I bought one about a year ago, mainly based on deal that included the pedal, and local support. As a TIG welder, it works fine, my only issues with it are the single knob to step through the different settings is a bit of a pain - other units have a few more buttons that make navigating the settings quicker, it has a stupid behaviour where in AC mode, when you adjust the amps, it resets the AC balance, which makes no sense, and there is no indication what the AC balance values correspond to. Also the torch and lead is big and heavy, and I often find my wrist is fighting the twist and weight of the lead.

    Apart from those niggles, I think it's good value for money, particularly if you can get the pedal as well.

    Thanks EFI_914,
    I was impressed by the size of the machine too, which is very compact. Thanks for the comment about the foot pedal, the one I use in my work place is soft which I am used to, in fact they have for me been all like that. Something to consider.. The pedal I saw had a adjustable rheostat on the side of it for selecting the amp range. And yes extra cost for the pedal.
    Thanks again.

    Hi RustyArc,

    Interesting the ergonomics on the machine you mention, was not aware of this. I am surprised that the controls are not so good on the Ac and that the Balance is hard to determine..
    I also asked about a lightweight torch for the Razor from the dealer (not available), as you say, when welding you definitely do not wish to fight with drag and or a clunky torch, just concentrate on the weld pool etc. Yes I agree, value is on par., Usually the Uimig build is very good.
    I looked at Tokentools machines and you can buy a nice lightweight TiG torch for there gear. Have not seen any recent reviews for there machines though.

    Thanks for your help.

    I picked up a cheap torch at Total Tools which is much lighter, and has a thinner, lighter hose - only downside is that the gas connection has to go straight to the bottle and can't use the unit's solenoid, so I have to open the valve at the torch before I light up, which wastes a bit of gas. It does make a big difference though, particularly for someone like me who is still learning.

    At some point I'll have to try and chase down a connector that matches the gas outlet on the front of the machine.

    I'm in the market for an AC tig and looked at the Razor, what put me off was the pretty poor duty cycle of only 20%. my other option is the tokentools machine which has a 60% duty cycle.
    Now I know we hobbyists/home welders probably,never get near the duty cycle but to me the machine must be built more conservatively if a higher cycle level.
    Another machine I looked at again with a pretty poor duty cycle was the CIG 200 Ac/dc and the knob on the front panel felt very flimsy too. Same with the Lincoln Powercraft model.

    I quite liked the look of the CIG 200 AC/DC - it has a few more buttons, so I expect it'd be a bit quicker to change options. However when I got the UniMIG, the CIG machine with pedal was considerably more expensive.

    My impression of the different Lincoln Powercraft machines I've seen is that they're pretty damn cheaply made.

    I have the DC only Razorweld 200, and am quite happy with the basic unit, it's been dead reliable for 3 years so far, and welds nicely. I find the single knob programming to be fine.

    Applicable also to the AC/DC version, the negatives are the large heavy torch, and for the price, the lack of a pedal. Silverwater Welding where I purchased it, can do a pedal for $200, and a nice lighter 17 size flex head torch for $160 including the Dinse connector that will connect the gas from the welding machine's internal solenoid to the torch. For $250 they can do an even lighter torch with an even more flexible cable.

    Graham.

    Thanks Oldbikerider,

    I think I was told, there was not a light torch for this machine (at your dealer). That's interesting. With a really light torch you could do some neat work.
    I have noticed on U Tube that many of the TIG welder's there use smaller torches in the demo's.

    Cheers

    The small torches you see on youtube are mostly 9 series, they are way better to use unless you're at high amps for long periods... in that case a 20 series water cooled torch is the go but they cost a bomb by the time you factor in the full set up.

    Im the same as others opinions on the razorweld gear the duty cycle is low like most cheaper machines(not that they are that cheap...) so I ended up going green with everlast(usually 60% DC).

    Hi Harry72

    As a result of your post here I had a quick look at the Everlast. Home base Port Macquarie? Have you had this machine long?
    I will now have a look at a 9 series torch. Be interesting.

    Cheers

    I have a size 9 torch on my dc tig light as a feather i have a 17 size torch on my AC machine and a few years mack i had to replace a torch i replaced it with a 26 size the only down side is the heavy cable within the torch but if u snag the cable up around the bench and have it come in from the side they are ok to use

    All torches have duty cycles as does the machines u need to work out your own combinations for what your welding
