superheated plasma (Fig. 3-3). The plasma cuts through the metal while
carrying the electrical charge. The charge transfers to the metal and
ground cable, completing the electrical circuit.
The electrode has an insert of tough high conductive material such as
hafnium and cerium (Fig. 3-1). The nozzle and electrode require periodic
replacement due to erosion with use. Clean, dry air improves the lifespan of
the electrodes and nozzle. A plasma air filter is recommended.
OVER-VOLTAGE
This equipment has an automatic voltage compensation function, which
enables the unit to maintain the voltage within the given range. In case
that the input voltage or amperage exceeds the stipulated value, it is
possible to damage the equipment's components. Please ensure your
primary power supply is correct (See Specifications).

DUTY CYCLE

The cutting unit's duty cycle rating defines how long the operator can cut
before allowing the cutting unit to cool. The duty cycle is a percentage of a
10 minute period. The cutting unit must cool for the remainder of the cycle.
This cutting unit has a duty cycle rating of 40% at the rated output (see
Specifications). This means that the user can cut for 4 minutes and then
rest the welding unit for 6 minutes before using it again.

THERMAL PROTECTION

Constantly exceeding the duty cycle can damage the cutting unit. An internal
thermal protector will open when the duty cycle is exceeded, shutting OFF all
cutting unit functions except the cooling fan. Leave the cutting unit turned ON
with the fan running. The thermal protector will automatically reset and the
cutting unit will function normally again once it has cooled.
Wait at least another 10 minutes after the thermal protector opens
before resuming cutting. Starting before this additional time may result
in a shortened duty cycle

PREPARATION

1. Check that all personal protective gear is in place and properly
fitted. (See Safety – Personal Safety).
2. Check that work area preparations are in place (See Safety – Work
Area).
3. Check that all cables and hoses are connected in the correct manner.
