Work Clamp Attachment

Connect the ground cable clamp to the work-piece to be cut or to the metallic workbench. Take
following precautions:
• Verify there is a good electrical contact particularly if insulated or oxidized coated sheets are
cut.
• Make ground connections as close as possible to the cutting area to reduce EMI.
• The use of the metallic structures that are not part of the work-piece, such as the return cable
of the cutting current, may endanger the safety system and give poor cutting results.
• Do not make a ground connection on the piece which has to be removed.
• The work clamp must be attached to the work-piece while cutting.

Connect Input Power Cord

Plug in the Forney 325P power cord to a proper 120V (20A) receptacle. A 120V (15A) receptacle can
be used with supplier adapter.

Power On the System

Set the ON/OFF switch on the rear of the machine to the On 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 in the on position. If the line voltage is suitable, the green light will
turn on. Activate the torch trigger to initiate the air putge. There will be a 1.5 second air flow
to remove any condensation that may have accumulated in the torch and air lines while the
system was shut down. When the air purge is complete, the pilot arc will be initiated.
