Parameters table update: new lab-tested entries for 0.1 / 0.15 copper
In the lab we welded 30 spots each on the UF20B, UK1 and P60F and took the median of the pull tests. Copper needs flux — without it the welds basically won't hold. This got asked in the comments so many times that we just wrote it into the table. The table is on the "Parameters" page, filterable by cell × material × thickness.
