Grounding Requirements; Air Supply; Torch Consumable Parts (Replacement Or Inspection Of Consumables) - Forney EASY WELD 20 P Manual De Instrucciones

Grounding Requirements

• To ensure personal safety, proper operation, and to reduce electromagnetic interference (EMI), the plasma
cutting machine must be properly grounded.
• The plasma cutting machine must be grounded through the INPUT POWER CABLE (3) according to national
and local electrical standards.
• Single-phase service must be of the 3-wire type with a green or green/yellow wire for the protective earth
ground. Do not use 2-wire service.

Air Supply

• The plasma cutting machine does not include a built-in air compressor; therefore, a source of clean, dry air or
nitrogen must be supplied to your plasma cutting unit.
• The air supply pressure must be between 60 and 100 PSI. NOTE: The flow rate is approximately 1.5 cu.ft./min.
• The unit will not operate if the input air pressure is below 55 PSI.
• Do not connect an input air supply over 100 PSI. Damage to the machine could occur.
• In-line particulate filtration is recommended upstream of the PLASMA CUTTING MACHINE to avoid damage to
the PLASMA TORCH.
• Failure to observe these parameters could result in excessive operating temperatures and/or damage to
PLASMA TORCH (9) or machine
MOISTURE SEPARATOR AND AUTOMATIC PURGE
• Oil and moisture in the air may damage the machine.
• The unit is equipped with an air filter, which captures the water and oil vapor in the supplied air.
• Water captured by the filter is automatically purged through the bottom of the machine.
• The equipped moisture separator is designed to remove small amounts of moisture and oil from the air supply.
If you are operating in a humid environment, it may be necessary to put additional filtering in the air supply
line before its input to the machine. Use additional filtering if a spray of moisture can be seen coming out of the
torch head during pilot arc, there are signs of moisture on the CUTTING TIP (D) or workpiece after cutting, or
cut quality is poor.
• Be sure and select a filter that is rated for the pressure and air flow requirements listed above.

Torch Consumable Parts (Replacement or Inspection of Consumables)

USE ONLY THE PLASMA TORCH (9) THAT CAME CONNECTED TO YOUR MACHINE OR A
CERTIFIED REPLACEMENT.
CAUTION! DISCONNECT INPUT POWER CABLE (3) FROM THE ELECTRICAL OUTLET AND
WAIT FOR THE PLASMA TORCH TO COOL BEFORE REMOVING THE SHIELD CUP (E). IT
IS EXTREMELY IMPORTANT THAT YOU CAREFULLY READ THESE INSTRUCTIONS BEFORE
CHOOSING THE CONSUMABLES FOR YOUR PLASMA TORCH. THIS WILL PREVENT
DAMAGE TO YOUR PLASMA TORCH AND PLASMA CUTTING MACHINE.
BEFORE BEGINNING CUTTING OPERATIONS, VERIFY THAT THE PARTS ARE PROPERLY ASSEMBLED BY
INSPECTING THE BODY OF THE PLASMA TORCH AS SHOWN BELOW
THE PLASMA ARC FROM INSTANT-ON TORCHES CAN CAUSE INJURY AND BURNS.
CAUTION!
SWITCH (2) is OFF and the machine disconnected before changing consumables.
