INSTALLATION PROCEDURES 16 Manual 0-2803
3.09 Connecting Torch Leads
WARNING
Disconnect primary power at the source before as-
sembling or disassembling the power supply, torch
parts, or torch and leads assemblies.
The Torch Leads must be properly installed to the Power
Supply for proper operation. If the torch leads were not
factory-installed, make all torch connections to the Torch
Bulkhead Panel for the desired application.
NOTE
Equipment ordered as a system will have the Torch
factory connected to the Power Supply.
CAUTION
This system is designed for use with the PCH-102
torch only. Do not connect any other torch to this
power supply.
1. Remove the Cover of the power supply to gain access
to the torch bulkhead panel.
2. Remove the securing nut from the strain relief sup-
plied on the end of the Torch Leads.

3. Feed the torch lead ends and the Strain Relief into the
hole in the unit.
4. Secure the Strain Relief with the retaining nut removed
earlier.
5. Connect the torch Negative/Plasma Lead to the bulk-
head connection inside the Power Supply.

7. Remove the top nut and washer from the Pilot Stud.
8. Place the lug on the Pilot Control Wire onto the stud
and secure with the nut and washer removed in the
above Step.
9. Tighten the Strain Relief onto the Torch Leads.
10. Check the torch for proper parts assembly.
11. Re-install the Power Supply Cover on the Power Sup-
ply.
3.10 Work Cable And Ground
Connections
A. Electromagnetic Interference (EMI)
Pilot arc initiation generates a certain amount of electro-
magnetic interference (EMI), commonly called RF noise.
This RF may interfere with other electronic equipment
such as CNC controllers, etc. To minimize RF interfer-
ence, follow these grounding procedures when install-
ing mechanized systems:
B. Creating an Earth Ground
1. Install a ground wire (not included) between the sys-
tem and a solid earth ground (also called star ground).
To create a solid earth ground, drive a 1/2 in (12 mm)
diameter copper rod into the earth so that the rod con-
tacts moist soil over most of its length. The required
depth will vary depending on location (see NOTE).
Locate the rod as close as possible to the power sup-
ply. The work table should be connected to the same
earth ground as the power supply.
