The FPP70 works in conjunction with the Duro Dyne MF70 compact pinspotter (sold separately). The FPP70 is fully assembled for pneumatic and electronic controls to allow the MF70 welding source to be utilized as both a hand held pinspotter and a fixed head pinspotter. This provides the customer with greater capabilities at a lower cost. The MF70 when used with the FPP70, will weld pins from 1/2 inch to 2 inches long on 26 to 20 gauge.
