Section I: Features
Features
The Phasemaster™ 6 (PM6) is a single-phase, absolute-count, NEMA type BS2HX, bench mounted,
sequence welding control that has the flexibility to effectively solve most resistance welding problems. The
circuitry used in the PM6 is microprocessor based, convection cooled, with conservatively rated
components. The design ensures safe, repeatable operation in adverse environments. Special precautions
protect against false triggering in high RFI and EMI environments. The PM6 includes power input and
output cables and connectors for easy installation with a Unitek Peco Welding Transformer. It is a multi-
voltage unit designed for operation at 100, 115, 208, or 230 VAC, 50/60 Hz. These models are supplied
with a line cord, suitable connector, and a 30 amp combined circuit breaker/power switch. The PM6/460 is
designed for operation at 220, 380, 415, 440, or 460 VAC. The PM6/460 requires a user supplied circuit
breaker, disconnect and input wiring.
