Just wondering if anyone can explain to me how to set up my esab smashweld 160. I had it given to me by a friend but I'm struggling to understand what the top two knobs do?
Thank you for any help in advance. J
Welcome to the forum.
They look like spot and stitch timers.
Although it's quite faded the knob below looks to have 3 positions, to the left will be continuous welding, the middle will be spot welding (top left knob) and the right will be stitch welding (top right knob).
If you select the spot or stitch positions it activates the relevant knob above which controls the on/off timers.
Spot welding - press and hold the trigger, it will weld for the preset time then stop, release the trigger, move to the next position, press and hold - weld - stop.... etc.
Stitch welding - press and hold the trigger, it will weld for the preset time then stop BUT... will pause then start again on it's own for as long as you've got the trigger pressed. Basically trigger held = weld - pause - weld - pause and so on).
