3.12 Height Control Connections
The terminal strip has Arc Volts (-) connection to power supply negative output TORCH terminal, Arc Volts (+)
connection to power supply positive output WORK terminal. These are for a height control that requires
connection to the full non-divided arc voltage. Also available on the terminal strip are 120VAC (120,0) and 24
VAC (24, 0). Note that the two 0’s are not common. The allowable current draw is 100ma @ 120VAC and 1Amp
@ 24 VAC.

NOTE
There is also a hole added in the rear panel above the J55-GCM receptacle for customer wiring. This,
rather than the one in the CCM will be the preferred place for customer added wiring (and strain relief) for
connections to height controls, etc..
3.13 DMC-3000 Gas Manifold Control Installation
The DMC-3000 Gas Control must be installed in a suitable location where it is easily accessible to the system
operator. The unit must be mounted to a flat horizontal surface. If the Module is mounted to any support subject
to vibration or motion, the installer must fasten the module to the support securely.
The Module should be located as far away as possible from the Arc Starter due to electromagnetic interference. It
is acceptable to locate the control cable in the same track as the cables from the Arc Starter.
The Module includes feet which lift the bottom panel off the mounting surface. There are ventilation holes on the
bottom panel; the space between the bottom panel and the mounting surface must remain open for ventilating air
to enter the module. Louvers on the back panel of the module must also remain unblocked, for the free passage
of ventilating air.
