USER MANUAL

v.1.1
•
If working on a metal wall, ceiling, etc, prevent ignition of combustibles on the other side by moving the objects to a safe location. If reloca-
tion of combustibles is not possible, designate someone to serve as a fire watch, equipped with a fire extinguisher, during the cutting process
and for at least one half hour after the cutting is completed.
•
Do not weld or cut on materials having a combustible coating or combustible internal structure, as in walls or ceilings, without an approved
method for eliminating the hazard.
•
Do not dispose of hot slag in containers holding combustible materials. Keep a fire extinguisher nearby and know how to use it.
•
After cutting, make a thorough examination for evidence of fire. Be aware that easily-visible smoke or flame may not be present for some
time after the fire has started. Do not weld or cut in atmospheres containing dangerously reactive or flammable gases, vapours, liquids,
and dust. Provide adequate ventilation in work areas to prevent accumulation of flammable gases, vapours, and dust. Do not apply heat to a
container that has held an unknown substance or a combustible material whose contents, when heated, can produce flammable or explosive
vapours.
•
Clean and purge containers before applying heat.
•
Vent closed containers, including castings, before preheating, welding, or cutting.
•
Do not touch live electrical parts. Wear dry, insulating gloves.
•
Do not touch electrode or conductor tong with bare hand. Do not wear wet or damaged gloves.
•
Protect yourself from electric shock. Always insulate yourself from the work piece and ground. Use nonflammable, dry insulating material if
possible, or use dry rubber mats, dry wood or plywood, or other dry insulating material big enough to cover your full area of contact with the
work or ground.
•
Never remove the grounding prong or modify the Power Cord Plug in any way. Do not use adapter plugs with this product.
•
Ensure that the unit is placed on a stable location before use. If this unit falls while plugged in, severe injury, electric shock, or fire may result.
•
Avoid overexposure to fumes and gases. Always keep your head out of the fumes. Do not breathe the fumes. Use enough ventilation or
exhaust, or both, to keep fumes and gases from your breathing zone and general area.
•
Use only compressed air at between 80-110psi. Never use oxygen, carbon dioxide, combustible gases or any bottled gas as an air source for
the plasma cutter. Such gases are capable of explosion and serious injury to people.
•
The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may
occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be
supplied by the operator.
•
Familiarise yourself with the specifications, rated duty cycles and operating instructions of this equipment.
•
The duty cycle defines the number of minutes, within a 10 minute period, during which a given plasma cutter can safely produce a particular
current as shown on the information label shown on the underside of the equipment:
