Information collected from User manual The Phasemaster™ 7 (PM7) is a versatile, single-phase, sequence welding control which can effectively solve most precision, small parts resistance welding problems. Its context-sensitive user help screens quickly guides you through even the most complex program. The PM7 can be used with manual, user-actuated, or air actuated weld heads. It is compatible with Unitek Peco’s exclusive UNIPULSE Transformer series, which guarantees repeat-able output energy even during half-cycle operation. UNIPULSE Transformers will operate at a 50% duty cycle when the weld period is an integral number of cycles. In unipolar, half-cycle operation, UNIPULSE Transformers can be used at rates up to five welds per second. You can program up to 128 weld schedules and save them in battery backup memory. A built-in schedule protection feature protects weld schedules from unauthorized or inadvertent changes. Schedule 0 serves as a scratch pad which anyone can use to perform occasional jobs without jeopardizing the integrity of the production line. The remote schedule selection feature allows you to reliably select weld schedules in automated applications. The PM7 is a multi-voltage unit designed for operation in the standard line voltage ranges of 90-110, 110- 120, 200-220, 220-240, 380-400, or 440-480 VAC, 50/60 Hz. The automatic line voltage compensation feature ensures that the weld quality will not be affected by normal fluctuations in line voltage, one of the major causes of defective welds. The unit is supplied with a line cord, and a 30-amp combined circuit breaker/power ON/OFF switch. The 460-volt unit requires a user-supplied circuit breaker, disconnect and input wiring. Features • Multi-function microprocessor control provides repeatable process control and is compatible with air or manually actuated weld heads. • User friendly, context-sensitive help screens guide you through work set-up and operation. • Digital display allows you to set welding current accurately and quickly. • Half-cycle welding capability is critical for the welding of small parts. • Automatic line voltage compensation compensates for up to ±13% changes in line voltage, which eliminates the major electrical cause of inconsistent weld quality. • 128 discrete weld schedules facilitate multiple applications at one work station. • Weld schedule protection feature protects 127 weld schedules from being changed by unauthorized personnel. • Remote weld schedule selection simplifies use in automated systems. • Chain schedule feature with automatic step function allows automation of simple tasks. • Ten unique weld functions provide solutions for the most complex welding applications. • Automatic power factor correction improves weld quality. • Air head capability is a standard feature which allows the unit to control single or dual air actuated weld heads, using separate weld schedules for controlling VALVE DRIVER 1 and VALVE DRIVER 2. • Unit is protected from radio frequency and electromagnetic interference to ensure reliable operation, even in high electrical noise environments. • Can operate on multiple line voltages: 90-110, 110-120, 200-220, 220-240, 340-400, or 440-480 VAC, 50/60 Hz.
