Supercapacitor in a pen: 1060A peak, 1.5M cycles, 10-second recharge, welds 0.3mm nickel/copper — the most capable handheld in its class.
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.
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.
One-year warranty on the unit, with a 7-day trial
