Safety features

A) Sparks on the tip/work piece

To avoid short circuits (arcing), the machine automatically
stops when the insert touches the work piece (metal to
metal contact). There is an inverter board that monitors
the amperage every millisecond. If the amperage sharply
increases creating a short, the system will automatically cut
the power to the tip to avoid any damage to the equipment.

B) Internal temperature

To protect the internal components of the machine, there
are temperature sensors inside the machine. If the operat-
ing temperature is too high, the machine will shut down and
restart by itself when the temperature reaches an acceptable
level. 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
circulation around the machine, fluctuations in amperage,
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 amperage is continu-
ally changing between positive (+) and negative (-).
Direct Current (DC) always flows in the same direction, but it
may increase and decrease. A DC amperage is always posi-
tive, but may increase and decrease.
