WARNING
the chassis must be connected to an approved
electrical ground. failure to do so may result in
electrical shock, severe burns or death.
400V cE Mains supply requirements:
High power equipment may, due to the primary current drawn from the mains supply, influence the pow-
er quality of the grid. Therefore connection restrictions or requirements regarding the maximum permis-
sible mains impedance or the required minimum supply capacity at the interface point to the public grid
may apply for some types of equipment (see technical data). In this case it is the responsibility of the
installer or user of the equipment to ensure, by consultation with the distribution network operator if
necessary, that the equipment may be connected.
WARNING
Before making any connections to the power
source output terminals, make sure that all
primary input power to the power source is
deenergized (off) at the main disconnect switch
and that the input power cable is unplugged.
A line (wall) disconnect switch with fuses or circuit breakers should
be provided at the main power panel (see Fig. 3-1 and Table 3-1 for
fuse sizes). The input power cable of the console may be connected
directly to the disconnect switch or you may purchase a proper plug
and receptacle from a local electrical supplier. If using plug/receptacle
combination, see Table 3-1 for recommended input conductors for
connecting receptacle to line disconnect switch.

1. For operator safety, the torch connections are located on the out-
put terminal board behind the lower portion of the front panel.
Remove access cover to output terminal compartment from lower
front panel of power source.
2. Thread the power cable, pilot arc cable and switch lead of the
PT-32EH through the open bushing of the cover. Connect power
cable to the torch fitting (left-hand threads); attach the pilot arc
cable connection to the Pilot Arc bulkhead adaptor; and plug in the
switch lead to the torch switch receptacle on the output terminal.
Make sure the power and pilot arc cable connections are wrench-
tight. Make sure plug of switch lead is firmly inserted in place.
3. Reassemble the access cover to the power source.
4. Connect your air supply to the inlet connection of the filter-regu-
lator.
5. Clamp the work cable to the workpiece. Be sure the workpiece
is connected to an approved earth ground with a properly sized
ground cable.
