    If you're going to get one, here's a few tips:

    Of course you'll need to modify the lower tong or make one. Make it similar to the one AKBuilder sells, or buy from Curtis!

    Reshape the pointed tips to slightly domed tips about 1/4 inch in diameter. The pointed tips will burn through your sheetmetal VERY quickly, and give poor, non-"original" looking welds if you manage to even get it to weld and not blow through. It might be best to just buy the tips Curtis sells.

    I had a 30 amp circuit I used when I first got the welder. Plugged directly into that circuit, it'd blow every 3-4 welds, so this spot welder draws more than the rated 30 amps. Burn-through, even with modded tips, was all too easy. Less than a second was needed for good welds, any more and it blew through.

    I solved the circuit breaker tripping and the quick blow-through by running the welder through a 50 foot 12-2 extension cord. Yes, that's the "wrong" way to do it, the old saying about not drawing more current through an power line than it's rated for applies. But, you're using it intermittently so the extra resistance helps while the cord shouldn't get hot enough to cause trouble if you use the welder appropriately.

    Let the welder cool off for a couple of minutes between EACH weld. You'll get more consistent results, better welds, less chance of burn-through, and the extension cord will stay cool.

    Clamp the metal to be joined using vise grips or clamps. Don't use the tongs for clamping, apply just enough force to the tongs to give a firm contact.

    Clean metal is always the best for spot welding, for this welder it's an absolute must. It's already on the edge of useability, adding variables pushes it over the edge.

    You can make very good welds with it, just learn how it works and use it with the tips above as some guidelines to get you on your way to some good looking AK rail welds!

    Oh, yeah. Before tackling that heirloom AK receiver, get some scrap and practice, practice, practice!

    Would you be interested in selling me the moving pieces that hold the top copper rod and pivot with the handle from your old spot welder? Mine are all loose and sloppy and have been since I bought it. Hard to get and hold clamping force adjustment.

    Stopped at Harbor Freight to look around today, the HF spot welders were $199 each.
