How to make small spot welder
Is the resistance pressure welding spot welding principle, the principle to understand you can spot, made. If the AC spot welding, is generally a transformer, a controller, coupled with the copper electrode, the clamping assembly, of course, the body is a must. If you need a more accurate, add a welded cylinder, driven by gas, and if it does not need to be very accurate, it will be used directly pedal type. If it is energy storage spot welder, it will be more trouble, and I suggest that you do a cost assessment before you do it. If it is too expensive, you might as well outsource it.

If you need a more accurate, add a welded cylinder, driven by gas, and if it does not need to be very accurate, it will be used directly pedal type. If it is energy storage spot welder, it is relatively more trouble, and I suggest that you do a cost assessment before you do, if it is too expensive, as well as outsourcing.
I have homemade, not easy to use, the cost is not low, and good and bad, bad, it is not worth the candle. The copper wire is expensive now, and the silicon steel sheet does not occupy much of the cost of the electric welding machine. Now mechanical and electrical products are not expensive, brothers suggest you buy one, but also warranty, electronic cheap more than 400, very light, and save electricity. Homemade welding machine to leakage magnetic flux, this bad calculation, on Taobao, look at the welding machine prices.
