SAFETY
Maintenance
Exposure to extremely dusty, damp, or corrosive air is damaging to the welding
machine. In order to prevent any possible failure or fault of this welding
equipment, clean the dust at regular intervals with clean and dry compressed air
of required pressure.
Please note that: lack of maintenance can result in the cancellation of the
guarantee; the guarantee of this welding equipment will be void if the machine
has been modied, attempt to take apart the machine or open the factory-made
sealing of the machine without the consent of an authorized representative of the
manufacturer.

Aip plasma cutting technology
Plasma cutters work by passing an electric arc through a gas that is passing
through a constricted opening. The gas can be air, nitrogen, argon, oxygen. etc.
The electric arc elevates the temperature of the gas to the point that it enters a
4th state of matter. We all are familiar with the rst three: i.e.,Solid, liquid, and gas.
Scientists call this additional state plasma. As the metal being cut is part of the
circuit, the electrical conductivity of the plasma causes the arc to transfer to the
work. The restricted opening (nozzle) the gas passes through causes it to
squeeze by at a high speed, like air passing through a venturi in a carburettor.
This high speed gas cuts through the molten metal.
Plasma cutting was invented as the result of trying to develop a better welding
process. Many improvements then led to making this technology what it is today.
Plasma cutters provide the best combination of accuracy, speed, and aord ability
for producing a variety of at metal shapes. They can cut much ner, and faster
than oxy-acetylene torches.
