A set containing the u-shaped and the straight aluminum part for the DIY Arduino Battery Spot Welder (They fit for V2 and V3). You do only need these parts for assembling your own Spot Welder with a PCB Set.
The parts are precision CNC machined and have a thickness of 4mm.
- The U-shaped part has 2.6mm holes (you can use M2.5×8 screws with M2.5 nuts or 2.4×8 rivets to mount it to the pcb)
- The straight part has 3.3mm holes (you can use M3x10 screws with M3 nuts to mount it to the pcb and the mosfets)
- The big holes are 6.5mm on both parts
Attention: The parts do NOT fit the old V1 of the Spot Welder. (the one with the 4 mosfet drivers)
