I have recently obtained a 240v 1100w microwave oven transformer to make myself a spot welder for battery packs.
There are a few different controller boards available and I am looking for some pointers on selecting which control board to use.
There seem to be 3 main ones available
The cheapest one seems to be
Geekcreit NY-D01 40A/100A Digital Display Spot Welding Module Time and Current Controller Panel Timing Ammeter Spot Welders Control Board - 100A
I think this is single pulse and comes in "40A" for AU$14.89 or "100A" for $19.36

Then there is this one
100A LCD Display Digital Double Pulse Encoder Spot Welder Welding Machine Transformer Controller Board Time Control Module
for AU$40.24
https://www.banggood.com/100A-LCD-D...-p-1380038.html?rmmds=search&cur_warehouse=CN
Or this one:
NY-D08 100A Spot Welder Controller Welding Machine Pneumatic Color LCD Display Multi-point Personalization with Temperature Sensor
also $40.24
https://www.banggood.com/NY-D08-100...-p-1569035.html?rmmds=search&cur_warehouse=CN
This one has a colour screen.
It alsoseems to add a temperature control - but I am not sure how that works with the rest of it?
It also talks about "no external power supply', but the diagram shows a 9-12v AC transformer?
It also says "pneumatic control", but I am not sure what that is for?
Then there is
https://www.ebay.com.au/itm/220V-Sp...attery-welder-includ-transformer/283114770145
Which seems to add a heatsink and transformer
Has anyone used any of there these?
Does anyone have some ideas on which to choose?
