UF20B at gear 60 welding 0.05 copper: on iron it tears two holes out; on a cell negative it’s a bit weak; nickel strip as a base layer recommended
A follower reported that 0.2 copper stacked on 0.2 nickel-plated steel strip wouldn’t weld; the creator says he doesn’t recommend 0.2 copper (very demanding on the machine). With an AWithZ UF20B + upgraded No. 6 welding pen at gear 60 he runs a same-settings comparison: 0.05 copper strip welded to a rusty iron pipe and to the negative of a Jiashikai cell. The welds on iron are blackened (high current), and pulling tears two holes out of the iron; 0.05 copper stacked on 0.12 nickel-plated steel strip on the cell negative peels off leaving two holes, not torn apart. Conclusion: at the same gear 60 the result on iron is clearly much better; use nickel strip as a base layer before welding copper for a stronger joint.
