CHAPTER 3: OPERATING INSTRUCTIONS
PHASEMASTER™ 6 DIRECT ENERGY WELDING CONTROL

PM6 Control Parameters
Weld Cycles, %Current:
1 Select Schedule 0. Weld Schedules can be developed using Schedule 0 and then they can be copied to any
other Schedule Number.
2 Switch Line Voltage Compensation to OFF. See Chapter 3, Section II.
3 Set WELD CYCLES to 0.5. See Chapter 3, Section I, Operation.
4 Set SQUEEZE and HOLD to 0 (Air Head Only).
5 Set %CURRENT to 60%.
Making a Weld
CAUTION:
Always observe safety precautions when welding. Wear your safety glasses.
1 Select [RUN] and [WELD] on the PM6.
2 Position the parts between the electrodes.
3 Press the footpedal or footswitch to initiate the Welding Sequence.
When weld current flows, the red pilot lamp on the UNIPULSE Transformer will light. It may be difficult to see in
those cases where the %CURRENT is less than 50% and/or when WELD CYCLES is set to 0.5.
Assuming no weld occurred, increase the tap switch setting until the parts just weld. In the event you reach the
highest
Primary Tap,
and
if applicable, the
highest
Secondary Tap without obtaining a weld, increase Weld Period
from 0.5 cycles to 1 cycle.
Use the %CURRENT to refine the characteristics of the weld.
The object should be to obtain a consistent weld with the SHORTEST WELD TIME, and a %CURRENT which is
between 60 and 90%.
