I have made many DIY spot welders, capacitor discharge, rewound MOTs and car battery type. The cheapest and easiest to get going is a group 24 - 27 car battery, solenoid and momentary push button or micro switch. All other types require alot of things that they don't tell you on youtube DIY...

The type of dimmer you need to handle a inductive load is called a Magnetic Low Voltage Dimmer, they are made to adjust the input voltage 0-120vac to a step down transformer/low voltage for lighting. I leave the shunts in my rewound MOT's because the transformers already draw too much current...

Wow, great link, best article I have found yet. Well if I cant weld battery tabs properly then I can always use the unit for resistance soldering station. I have a small American Beauty brand 250w resistance solder station for connectors and it does a good job, so 1400w should be amazing...

The control board came from ebay, I installed it in a old ups case, the green knob/readout adjust the timer, red knob/readout adjust the 120v power level going to the input of a transformer, the board has a triac that sets power cycle of the 120vac, I assume it will probably stay at 100% & only...

My DIY tab welder is waiting on the final piece, I need to know what would be the best weld voltage so I can wind the 1100w transformers secondary. I see utube videos that have anything from 1v output to ones using 12v battery, so weld voltage can vary alot. Does anyone know the open circuit...
