FAQU3加强版

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.

U3加强版最多能焊多厚?

官方实验室最大值:镀镍钢带 0.3mm,纯镍带 0.2mm,紫铜带 0.1mm,不锈钢带 0.3mm,铁片 0.3mm。不同材料批次与环境有差异,先在废料上试焊。

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?

锂电机型建议每 3 个月补电一次至 50–80%,避免高温与满电长期存放。
