Twin A-grade cells (5000mAh), 1380A / 9000W, 1500 welds; knob + digital display, dual pulse; welds up to 0.5mm (butt), nickel/copper/steel. ~370g, 1-year warranty.
No weld after power-on, or welds turn black — what to do?
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.
How often do I change the pins, and how?
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.
How do I store it long-term?
For lithium models, top up to 50–80% every three months; avoid heat and long-term storage at full charge.
How long is the warranty? Are accessories covered?
1 year on the unit
