Power On the System

Set the ON/OFF switch which is on the back of the power source to the On (I) position.

Cutting Operation

BEFORE OPERATING THE SYSTEM
CAUTION! Disconnect power source before disassembly of the torch. Check and follow instructions
including safety precautions presented in this operating manual.

Parts of the Torch

Check the torch for proper parts assembly order and installation (refer to Section called Torch
Consumable Parts Selection). NOTE: The power supply will not operate unless the torch shield cup is
fully seated against the PIP (Parts in Place) pins in the torch head.

Input Power

• Check the power source for proper input voltage.
• Make sure the power source meets circuit protection and wiring requirements.
• Plug unit in and close main disconnect switch to supply primary power to the system.

Work Clamp, Ground Cable

Check for a solid ground cable connection to the work piece.

Automatic Purge System

• Place the ON/OFF switch to the ON position. The ON light will flicker momentarily as the
system powers up and then stays on.
• Activate the torch trigger to initiate gas purge (pre-flow) to remove any condensation that
may have accumulated in the torch and leads while the system was shut down.
• When the gas purge is complete, pilot arc will be initiated.
• If during cutting there is still condensation exiting from the torch, stop cutting and turn unit
off. Wait for torch cooling to remove the shield cup. Dry the shield cup inside with dry air.

Checking Air Quality

• To check air quality, deactivate the torch (post-flow) and place welding filter lens in front of
the torch. Any oil or moisture in the air will be visible on the lens.
• DO NOT initiate pilot arc while checking air quality.
