The solar container spot welder does not work

If you find spot welder can’t be turned on or there is no response when inserting the charging wire, it is recommended to check the power adapter and charging wire. In this video, I bring a classic Solar 2-175 MIG welder back to life. This unit wouldn’t feed wire at all—it would arc, but the wire drive was dead. I tracked the issue down to a worn-out liner and . more In this video, I bring a classic Solar 2-175 MIG welder back to life. This unit wouldn’t feed. Step on the pedal, the welding machine does not work, and the power indicator does not light up: a. Check whether the power supply voltage is normal; check whether the control system is normal. b. Check whether the contact of the foot switch, the contact of the AC contactor, and the split shift. Hi all, I have a spot welder, pictured below with the covers off, but I can’t get it working. When I tread on the lower lever I can hear the transformer hum but no weld. I have cleaned EVERY contact between the power plug and the welding tips including the brass clamping blocks. It has three. This is a portable Farad capacitor-based welder: https:// it has worked very well for me, but the DC jack failed. I replaced the DC jack, but did not wait for the capacitors to discharge, and in the process accidentally shorted the green COM wire (that. I recently bought a spot welder for my 10S2P 21700 battery pack, I'm using 400A 12V car battery. Also I'm using 0.15x10mm nickel strips. The issue is that welds are weak (0.1mm are fine), but the thing is after 4-5 welds welding "prongs" and wires get noticeably warm to the touch (wires are 12AWG. why does my home made spot welder not work? Wrong kind of transformer. A real resistance welding xformer would have a different turns ratio, enabling a lot higher amperage in the secondary loop (think 1000's of amps, not 100's). And then your welding circuit has way too much impedance; the arms are.
