3.07 Connecting Torch Leads To
System Without Optional
Remote Arc Starter
NOTE
For Systems using the Optional Remote Arc Starter
refer to Section 3.13 for connecting the Torch.
WARNING
Disconnect primary power at the source before as-
sembling or disassembling the power supply, torch
parts, or torch and leads assembly.
The Torch Leads must be properly installed to the Power
Supply for proper operation. Make all torch connections
to the Torch Bulkhead Panel as follows:
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 Maximizer
300 Torch only. Do not connect any other torch to
this power supply.
1. Open the Access Panel to gain access to the Torch
Bulkhead Panel.
2. Remove the hardware attached to the power sup-
ply end of the leads assembly with a tie wrap.
3. Feed the connector on the end of the CNC Control
Cable through the rubber boot on the front panel of
the Power Supply (see NOTE).
NOTE
Feed the Control Cable through the rubber boot first
as there will not be enough space inside the rubber
boot for the connector if the Coolant and Gas Leads
have been fed through the rubber boot first.
4. Connect the CNC Control Cable connector to the
Control Cable connector on the Torch Bulkhead
Panel.
5. Feed the end of the Torch Leads through the rub-
ber boot.
6. Refer to the illustration. The Leads Assembly in-
cludes two leads shields; each shield includes two
ring-tongue connectors. Connect the Torch Leads
Shield Wires as follows:
a. Remove one nut and star washer from the torch
leads shield stud on the Torch Bulkhead Panel.
b. Place the ring lugs from the inner (RED) Torch
Leads Shield Wires over the shield stud on the
Torch Bulkhead Panel.
