Torch Leads to Impulse Start Console Connections

Perform the following steps to connect the torch leads to the impulse start console.

See Figure 6 on the next page.

Note: When making hose connections, only tighten the brass fittings enough to

make water or gas seals. The fittings are subject to damage if over tightened.

Braided Shield

1. Remove the threaded ring from the brass shield connector on the end of the braided

shield. Route the torch leads through the opening in the impulse start console and

push the shield connector through the hole until it is seated against the side of the

console.

2. Slide the threaded ring over the torch leads, thread it onto the brass shield

connector, and tighten firmly. The shield connector should ground the braided

shield to the case of the impulse start console in order to help reduce high frequency

noise emission. Using an ohmmeter, measure for zero ohms between the braided

shield and the ground stud located on the outside of the impulse start console.

Torch Electrode/Coolant Supply Lead

• Connect the torch electrode/coolant supply lead to the brass cathode manifold. Note

that the torch electrode/coolant supply lead has right hand threads.

Torch Coolant Return Lead

• Connect the torch coolant return lead to the brass cathode manifold. Note that the

torch coolant return lead has left hand threads.

Torch Nozzle Lead

• Connect the torch nozzle lead to the angled bracket on the red standoff. Note that

the torch nozzle lead has right hand threads.

Torch CTP Sensor Lead

• Connect the #18 AWG torch CTP sensor lead to the red standoff as shown.
