    Thermal Arc and Lincoln Mig Whips?

    Do Thermal Arc and Lincoln mig welders share the same style back end that plugs into the welder?

    Would need to know which specific machines. Some Lincoln have a special Lincoln plug and some use a Tweco plug. Thermal Arc might be Tweco but not sure.

    Lincoln has 2 back ends. Tweco #4 and their own that is similar but larger diameter. They are switching back to the Tweco # 4 style. Thermal Arc And Tweco are both Thermadyne/Victor brands and the guns are the same.
    Thermal Arc 320SP ( Lorch )
    Cobra Pythons
    Thermal Arc 300 AC/DC ( Sanrex )
    ESAB 301i AC/DC ( Lorch )
    Thermal Arc 161STL ( WTL )
    Thermal Arc 190S ( Sanrex )
    Cut Master 82, 42. Cut45 ( WTL )
    Victor Gas Apps.
    Boxes and boxes of welding crap.

    Josey......what about the small connector? Are you saying that the small connector works between the Lincoln 180 and the TA 181I?

    Hi. Enter Tweco rear connector plug no 350174H that seems to be standard on Lincoln and thermal arc. I see you can buy them cheaper on Amazon.

    Jonesy i was referring to the very small connector that works off the mig gun trigger.....is this switchable between both machines?
