CUTTING SERIES EQUIPMENT

WARNING FLYING SPARKS and HOT METAL
can cause injury.
Chipping and grinding cause flying metal. As welds cool, they can throw off slag.
1. Wear approved face shield or safety goggles. Side shields recommended.
2. Wear proper body protection to protect skin.
WARNING ARC RAYS can burn eyes and skin,
NOISE can damage hearing.
Arc rays from the welding process produce intense heat and strong ultraviolet rays that
can burn eyes and skin. Noise from some processes can damage hearing.
1. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes
when welding or watching;
2. Wear approved safety glasses. Side shields recommended;
3. Use protective screens or barriers to protect others from flash and glare;
warn others not to watch the arc;
4. Wear protective clothing made from durable, flame-resistant material(wool and leather)
and foot protection;
5. Use approved ear plugs or ear muffs if noise level is high;
6. Never wear contact lenses while welding.
WARNING FUMES AND GASES can be hazardous
to your health.
Welding produces fumes and gases. Breathing these fumes and gases can be hazardous
to your health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to remove welding fumes
and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Work in a confined space only if it is well ventilated, or while wearing an air-supplied
respirator. Shielding gases used for welding can displace air causing injury or death.
Be sure the breathing air is safe.
5. Do not weld in locations near degreasing, cleaning, or spraying operations. The heat
and rays of the arc can react with vapours to form highly toxic and irritating gases.
6. Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless
the coating is removed from the weld area, the area is well ventilated, and if necessary,
while wearing an air- supplied respirator. The coatings and any metals containing these
elements can give off toxic fumes if welded.
WARNING WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The fly sparks and hot metal, weld spatter,
hot workpiece, and hot equipment can cause fires and burns. Accidental contact of
electrode or welding wire to metal objects can cause sparks, overheating, or fire.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables far away from the welding arc. If this is not possible, tightly
cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can easily go through small
cracks and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
WARNING CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can
explode. Since gas cylinders are normally part of the welding process, be sure to treat
them carefully.
1. Protect compressed gas cylinders from excessive heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position by chaining them to a stationary support
or equipment cylinder rack to prevent falling or tipping.
3. Keep cylinders away from any welding or other electrical circuits.
4. Never allow a welding electrode to touch any cylinder.
5. Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the
specific application; maintain them and associated parts in good condition.
6. Turn face away from valve outlet when opening cylinder valve.
7. Keep protective cap in place over valve except when cylinder is in use or connected
for use.
8. Read and follow instructions on compressed gas cylinders, associated equipment.
WARNING ENGINE FUEL can cause fire or explosion.
Engine fuel is highly flammable.
1. Stop engine before checking or adding fuel.
2. Do not add fuel while smoking or if unit is near any sparks or open flames.
3. Allow engine to cool before fuelling. If possible,check and add fuel to cold engine before
beginning job.
4. Do not overfill tank — allow room for fuel to expand.
5. Do not spill fuel. If fuelling is spilled, clean up before starting engine.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire on the
hidden side.
7. Do not weld on closed containers such as tanks or drums.
8. Connect work cable to the work as close to the welding area as practical to prevent
welding current from travelling long, possibly unknown paths and causing electric
shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off welding wire at contact tip when not
in use.

◆Operating Manual
The rated duty cycle of a Welding Power Source is a statement of the time it may be
operated at its rated welding current output without exceeding the temperature limits of the
insulation of the component parts. To explain the 10 minute duty cycle period the following
example is used. Suppose a Welding Power Source is designed to operate at a 60% duty
cycle, 70 amperes at 108 volts. This means that it has been designed and built to provide
the rated amperage (70A) for 4 minutes, i.e. arc welding time, out of every 10 minute
period (60% of 10 minutes is 4 minutes). During the other 6 minutes of the 10 minute period
the Welding Power Source must idle and be allowed to cool.

To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.
The socket information is included in the event the supplied cable is not suitable and it is
necessary to wire a plug or cable to interface with the receptacle.
3. Thermal Overload Indicator Light
This welding power source is protected by a self resetting thermostat. The indicator will
illuminate if the duty cycle of the power source has been exceeded. Should the thermal
overload indicator illuminate the output of the power source will be disabled. Once the
power source cools down this light will go OFF and the over temperature condition will
automatically reset. Note that the mains power switch should remain in the on position
such that the fan continues to operate thus allowing the unit to cool sufficiently. Do not
switch the unit off should a thermal overload condition be present.
8. Pilot connection
The plasma torch is connected to the pilot port on the machine. Here is theArc generated
by pressing the button on the burner. (contactless ignition).
