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 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
To restart the machine, simply press the Hand Wand ON button.
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 10 Amps. If the
amperage goes above 10 Amps, the machine automatically shuts down.
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 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.
The inside temperature can increase for many reasons: high ambient temperature, lack of proper
air circulation around the machine, fluctuations in voltage, electrical set-up in the shop, etc.
Example: On a flat surface, the amperage is around 8
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 10 Amps and the
