UF20B FAQ
First make sure the pins are pressed firmly and the surface is clean; start low and step up — 0.1–0.15mm Ni-plated steel usually needs only a low-to-mid level. Look up settings by cell model × material in the WeldWorld parameter lookup.
Official lab maximums: Nickel-plated steel strip 0.4 mm, Pure nickel strip 0.3 mm, Copper strip 0.2 mm, Stainless strip 0.4 mm. Results vary with material batch and conditions — test on scrap first.
Pins are consumables — dress or replace them when welds enlarge, spark often or blacken noticeably; see the manual's pin-change section and the Academy videos for steps.
Supercapacitor models need no charge maintenance — store them dry at room temperature; on next use, plug in for about 10 seconds to recharge.
