PHASEMASTER™ 6 DIRECT ENERGY WELDING CONTROL

Footswitch
A 1-Level or 2-Level Footswitch is required to control Air Actuated Weld Heads. The PM6 will
automatically detect whether a Unitek Peco 1 or 2-Level Footswitch is connected to the Footswitch
Connector located on the rear panel. The PM6 assumes that a 1-Level Footswitch is used if the input to the
2nd Level is continuously closed. Refer to Footswitch Connector. The PM6 detects Footswitch type and
lights the Footswitch indicator only on power up. If an Air Head connection is detected, the default
condition for the Footswitch indicator will be 2-Level even if there is no Footswitch connected.
NOTE:
Any connection made after power up will not change the indicator.
Initiation
If the PM6 is connected to a Manual Head, the Initiation Switch is the Force Firing Switch located in the
weld head. Either the Firing Switch Connector
or the Optical Firing Switch Connector is used.
If the PM6 is connected to a Air Actuated Head, the Initiation Switch is the Footswitch. The 1st Level of a
2-Level Footswitch instructs the PM6 to: (a) switch ON the Valve Driver which causes the upper electrode
of the weld head to apply force, as determined by the air regulator connected to the top of the air cylinder on
the head, to the workpiece; and (b) to start the Squeeze Period. The 2nd Level initiates the start of the Weld
Period, provided that the Force Firing Switch has closed AND the Squeeze Period has ended. A 1-Level
Footswitch combines the functions of both levels of a 2-Level Footswitch.
Footswitch Weld Abort On
The welding sequence is initiated by the closure of the Initiation Switch and continues to its conclusion as
long as the Initiation Switch remains closed. Should the Initiation Switch open during the welding
sequence, the sequence will terminate within one cycle after the switch opens. FOOTSWITCH WELD
ABORT ON is preferred since it allows the operator to abort the welding sequence by releasing the
Footswitch or Footpedal, in the case of a Manual Head.
Footswitch Weld Abort Off
The welding sequence is initiated by a single, momentary, closure of the Initiation Switch. Opening the
Initiation Switch during the welding sequence will NOT terminate the welding sequence. The Initiation
Switch must open and then re-close in order to start the next sequence. FOOTSWITCH WELD ABORT
OFF is used in automated process control systems where operator intervention is not an issue.
