Safety features

A) Sparks on the tip/work piece

To avoid short circuits (arcing), the machine automatically
stops when a metal to metal contact happens. There is an
inverter board that monitors the voltage every millisecond.
If the voltage sharply increases creating a short, the system
will automatically cut the power to the tip to avoid any
damage to the equipment.
To restart the machine, simply press the hand wand
ON button.
!
WARNING
To avoid drawing too much amperage
and automatically stopping the power to the tip,
make sure that you touch only one surface at a time.
The machine is set to work at a maximum of 15
amps. If the amperage goes above 15 amps, the
machine automatically shuts down.
Example: On a flat surface, the amperage is around
12 amps. The contact surface area is relatively small.
Example: An internal angle, which if you touch 2 sides
simultaneously, the contact surface area is doubled,
amperage goes above 15 amps and the machine stops.
Note: Automatic shut off if ground is not detected within 20 seconds.

B) Internal temperature

To protect the internal components of the machine, there
are temperature sensors inside the machine. If the operating
temperature is too high, the machine will shut down, the
corresponding LED on the front panel with light and the unit
will restart by itself when the temperature reaches an
acceptable level. The corresponding LED will then turn off.
light on. There is an internal fan inside the machine to keep
all the components cool.
!
WARNING
The inside temperature can increase
for many reasons: high ambient temperature, lack of
proper air circu-lation around the machine, fluctuations
in voltage, electrical set-up in the shop, etc.

C) AC/DC current basics

Alternating Current (AC) flows one way, then the other
way, continually reversing direction. An AC voltage is
con-tinually changing between positive (+) and negative (-).
Direct Current (DC) always flows in the same direction,
but it may increase and decrease. A DC voltage is always
posi-tive, but may increase and decrease.
