Safety features

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 continually
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 positive,
but may increase and decrease.
