The RH Mach 70 Pinspotter features a more efficient transformer that provides a wider range of welding capabilities. The Heavy Duty Vibrator Bowl and base weld pins up to 2’’ and the optional manual feed accommodates pins up to 4’’ on 4’’ insulation. A floating upper weld tip and an optional lift kit are among some of the improvements to this Pinspotter. The RH Mach features the Rolling Head for easier material handling. It also features a notch on the support bar to easily accommodate TDC/TDF duct. The ability to move the trolley instead of the ductwork minimizes material handling. This feature coupled with utilization of welded pins will insure your shop of a cost efficient, quality product.
