A project log for Spot Welder & Bag Sealer Timer Board

This is a simple Timer and SSR board to implement in the well known DIY MOT spot welder, and also is meant to replace a bag sealer board.

Made a quick thru-hole prototype, totally forgot the capacitor in series with the microswitch

 and had to add it directly to the switch terminal.

That capacitor make sure that if you mantain the switch pressed close, the timer won't keep output in a high level, making the welder never shut down and keep outputing current.
