    MIG welding small items?

    What kind of tricks does anyone have for welding small items? By small I mean no room to put the ground clamp. For example, how would you weld two quarter sized steel washers together?

    I consider it a vice to hurt a vise.
    Mac, I clamped onto the fixed jaw. Shortest path.

    "THEY" don't make high amperage tiny ground clamps, because anyone who has a need for one, makes it, or has a grounded micro welding fixture. What you want, (as well as a piece of metal plate to weld on) is something to put your ground clamp ON, (EG a 1/8 or 5/32" rod stub, as in #5 above) OR a grounded holder

    Take pair of small pointed vicegrips and weld "stud" on top side and connect ground cable to stud...You are welder /fabricator, adapt!

    Do a search for 'welders third hand', that's what northwelder was referring to as grasshopper. It's got several names. Nothing elaborate needed. Make several.

    1. Drill or use existing holes in welding table to use a drill- press hold-down jig or, a clamp made from a cheap pair of visegrip cones.

    2. Construct a universal jig to attach to your table of the type used in welding schools to hold practice coupons.. This can be used to hold any type of clamp or tool holding the the weld metal. with ground attached on jig.

    3. Buy small cheap (expendable) C clamps.

    4. Make a tiny grasshopper.

    5. If all else fails, tack something to it and ground that, and repair the damage later.

    Clamp together with Vice grips and put ground clamp on vice grips.... Done that with items "C" clamped together, by just putting ground on "C" clamp....I know it violates the put ground as close as possible to area to weld, but it works.... Other solution is to forget the weld and use other form of fabrication...
