Function & Control; Work Clamp Attachment; Connect Input Power Cord - Forney Plasma Torch Manual De Instrucciones

1. Position the torch with the shield cup facing upward to prevent these parts from falling out.
2. Install the electrode, air diffuser ring, and nozzle.
3. Hand-tighten the shield cup until it is seated on the torch head. If resistance is felt when
installing the cup, check the threads before proceeding.
4. Included in the parts bag with your machine are 1-each of an electrode and nozzle for future

1. ON/OFF Switch – In the ON position the machine is ready for normal operation. All system
control circuits are activated. OFF position deactivates control circuits.
2. Green LED– It blinks for a few seconds to show that capacitors are being charged and that
the unit is getting ready for operation. It turns ON when input voltage is applied within
normal range – blinks slowly when input voltage goes above 135VAC, or below 85VAC.
3. Yellow LED– Turns ON when the thermal protection is activated.
4. Red LED–Turns ON when torch is triggered. Blinks quickly during pre-flow prior to pilot arc
ignition. Blinks slowly if cutting arcs not initiated after 3-second pilot arc ignition.

7. Input power cable

Work Clamp Attachment

Connect the ground cable clamp to the work-piece to be cut or to the metallic workbench. Take
following precautions:
• Verify that 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 exposure electric
and magnetic fields (EMF).
• The use of the metallic structures which 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 250P+ power cord to a proper 120V receptacle.
