    Default new mig gun for transmig 135

    hi. is anyone able to tell me the connection type for the transmig 135. the one i have on it now is stock and really pissing me off because the gas valve button thing is really hard to depress and you have to exert alot of pressure on the trigger to get it to weld. not good when trying to concentrate.

    has anyone converted to a nice tweco torch or similar and can share their knowledge?

    Hi fabricator,
    The gas valve button is only a microswich which activates the drive wheel and electrical power contactors and the gas solenoid valve.
    Before you spend any time on this ,is the trigger able to be cleaned, disassembled and adjusted?

    It may only take a tweek on a spring and to remove some grunge.Failing that you might adapt a small microswitch as the control voltage is only 32 Volts which would make it acceptable to self repair.

    After looking at the unit ages ago in Bunnings I seem to recall that the assembly is a bayonet type. If the trigger can't be repaired a generic replacement unit can be obtained .

    I do know that Global welding carries them and its likely you can get one that fits or be able to be adjusted to the original bayonet fitting.

    its looks like that the one on p 56 might be the go. It will take generic spares.
    I have converted a buggerd sip torch (toy) to the profax torch and it worked a treat.

    Does this help?

    Hi Fabricator

    Dont know if your still in the market for this but think graham may have sent you down the wrong path (no disrespect graham, have read a few of your replys and your normally spot on) but this machine does not use conventional mig torches being that it actually doesnt have a gas solenoid. It uses a gas valve type trigger which is the reason for the hard trigger. Cigweld have these torches but the last time i looked you could just about purchase a new machine for the price!!! Unimig/Welding guns of Aust. have replacements for this machine but you cannot retrofit any type of "normal' mig gun due to the fact that it has a solenoid in the handpiece. Sorry for the bad news.... I'm a dealer so if u need help just ask, have refurbed these before...

    Sorry about that.

    My knowldge of mig gun connections is good but not perfect.
    I would expect that this would be picked when the gun was taken in to Global.

    hey! Don't worry about it.
    I am no guru and thats for sure, long hair and loincloths are not conducive to welding safety.

    However, I am nearly as old as dirt and have studied and taught much of the subject matter discussed here in the forum.
    I am wrong occassionally.Even though in am not directly connected to industry , I still visit workshops as part of my teaching, so I am keep up. I read all that I can on the net and find there is a lot of incorrect information about there on websites, particularly websites written by amatuers with short term experience who cut and paste more incorrect info from other crap websites. I really get the irritts. when these charecters just write rubbish and proclaim its "how to weld".

    Take no notice its just me and if I think its wrong I'll tell eveyone .I have no problems anyone pointing it out when I make a blue. Hey,we are all human.!!


    I would expect that this oversight would be picked when the original gun was taken in to Global.
    I have no idea what gas solenoids cost, but am reasonably sure one can be picked at a reasonable price. A gas solenoid with the new welding torch would overcome even that problem.
    Is it cost effective to do so,? orelse just put up with the problem?

    Default transmig

    Nah in my experience its not worth trying to wire in a gas solenoid. Has no bayonet either its a direct connect so either need to fit a euro or bayonet which is far too expensive by the time you pay for the gun too and theres only one trigger wire too. Can get a new 175i inverter mig/tig/arc for about the same price that would cost, not a bad little machine for hobby/price....sorry to be the bearer of bad news...the machines pretty much a newer model of the old cigweld due mig if anyone remembers those?? Best forgotten in my opinion....
