So how does this (lead free paste Sn42/Bi58) solder compare with the Sn-Ag-Cu (Tin-Silver-Copper) combination which does not flow as well (in the oven), needs higher oven temperature, (that can be adjusted by reducing the oven chain speed) and cost m

If N2 is not an option, the cut wire feeder or drilled wire are your best bet for now. You need to optimize wire feed rate as well. The solder joint on the robot takes about the same time to form as in manual soldering. If you need to speed the solde
