#Pro spot welder

Is there a lookup table for the welding gears vs nickel-plated strip (nickel strip)?

The creator picks up an AWithZ UF20B (AWithZ focuses on spot welders; a must-have for repair / DIY): main unit, manual, power cord, welding pen and a free roll of nickel strip. Neat finish, cooling fan at the rear, a slot on the base so it also cools when stood upright; max output current 1750A, officially rated for 0.15mm copper strip and 0.4mm nickel strip. On power-up the screen shows the AWithZ logo and the internal supercapacitor charges first, done in moments; long-press to power on, short-press the power key to switch settings; the trigger port takes a foot switch, set to foot-pedal mode. The default gear 05 is on the low side, max is 100; after welding nickel strip the welds are bright as new with no blackening, and pulling on the strip tears the strip while the welds hold tight. Key point: a higher gear is not a stronger weld — too high burns through and wrecks the strip and the weld is actually weaker; like a soldering iron’s temperature, right is right. Commenters ask for a ‘gear vs nickel strip thickness chart’.
