Keep off combustible when cutting.

6
Keep hot workpiece after cutting away from flammable gas.
Do move away the combustible around when cut the dooryard, ground andwall,.
The wire connection of base metal should be as close to the cutting place aspossible.
Never cut those facilities with gas pipe or airtightslot.
Put fire extinguisher around the cutting area to preventfire.
The gas and fumes are harmful to health, please wear protective
device according to regulations.
Wear exhaust equipment and breathe preventive facilities to prevent gas poisoning or choke.
Use suggested part exhaust equipment and breathe preventive facilities to prevent hurt or
poisoning by gas and other powder,please.
To prevent oxygen-deficiency, air out the gas-filled room which is full ofCO2 and argon on the
bottom, when operating on trunks, boilers, cabins,etc.
Please accept the supervisor’s inspection when operating in narrow space. Air the room and
wear breathe preventivefacilities.
Never operate in degrease, washing or sprayspace.
Using breathe preventive facilities when cut shielded steel for it will cause poisonous dust and
gas.
The arc, spark, residue and noise are harmful to health, please wear
protective appliance.
Eye protection against arc is recommended when cutting or supervise cutting.
Please wear preventive spectacles.
Operator’s gloves, operator’s goggles, long sleeve clothes, leather apron, and other
standard protection equipments must be worn for cuttingoperation.
A screen to protect other people against the arc must be set in the cuttingplace.
Please follow the notes below to avoid gas cylinder toppling over or
broken.
Use the gas cylinder correctly.
Use the equipped or recommended gaseousregulator.

or the shooting wire may stab your eyes andface.
Keep your eyes, face or other naked parts away from the end of torch when feeding the wire
manually or pressing the switch.
For better work efficiency and power source maintenance, please
note the following.
Precautions against toppling over.
Never use the cutting equipment for pipethawing.
Lift the power source from side when use the up-down forklift truck to avoid topplingover.
When using the crane for lift, tie the rope to the ears with an angle no more than φ15 to the
vertical direction.
When lifting the plasma cutting machine which equipped with gas cylinder and wire feeder,
download them from the power source and ensure the horizontal of the machine. Do fix the
gas cylinder with belt or chain when moving it to avoid bodyhurt.
Ensure fastness and insulation when lifting the wire feeder through the swing ring forcutting.

MACHINE DESCRIPTION
The plasma welding machine adopts the most advanced inverter technology, it’s applicable for
plasma cutting system with compressed air.
The development of welding and cutting equipment benefits from the appearance of the inverter
power supply theory and components.
Inverter cutting machine, firstly transfers the working voltage of 50/60Hz to high frequency (above
100KHz) via high-power device MOSFET, then reduces the voltage and adjusts the current, delivers
high-power cutting current via PWM technology.
Compared with traditional cutter, inverter technology has advantages of low energy consumption, light
weight, compact and excellent performance.
The Plasma Cutting Machine series can provide more powerful, concentrated and stable electric arc.
The arc temperature can rise up to 10,000-15,000℃, forming powerful plasma arc. That means the
plasma arc can be applied to cut metal rapidly, and make its heat affluence area as small as possible,
energy to be efficiently utilized, also can get a very smooth cutting section, which greatly facilitates
consequent processes.
The welding machine series can be easily designed into different cutting power sources, whose
output current is constant and adjustable. With excellent operation performance, its transfer efficiency
is commonly above 85%.
The machines have been widely applied in many areas, primarily focus on metal plate cutting and
special situations that are not suitable to be applied and achieved with common devices. Applicable
for various metal materials with different characteristics, including stainless steel, alloy steel, carbon
steel, cuprum and other ferrous metallic materials.
Compared with the others cutting machines, this cutting machine series provide functions of quick
power adjusting and controlling via advanced circuit module. Moreover, they have first-class cutting
operation and the enormous transfer efficiency.
Thanks for purchasing our products and looking forward to your precious advice. We will be dedicated
to provide our best products and service.
