FURTHER CONTROLS EXPLAINED

Overload/ Error Indicator

Lights when over voltage, over current or electrical overheating
(due to exceeding duty cycle) is detected and protection is
activated.

When protection is activated, welding output will be disabled until
the safety system senses the overload has reduced suciently
and indicator lamp goes out. May also trigger if machine
experiences an internal power circuit failure.

Lift TIG Mode

Lift TIG is an arc ignition system for basic TIG welding that
removes the need to ‘scratch’ start or strike the tungsten on the
work piece to start the arc, which can have a negative eect on
the weld quality due to tungsten contamination. Lift arc starting
works by gently touching the tungsten on the work piece and
then lifting it o. The control circuit will sense when the tungsten
is removed from the work piece and send a pulse of electricity
through the torch that will cause the TIG arc to initiate.

VRD Function

VRD stands for Voltage Reduction Device. This is a safety system
that reduces the output voltage from the welding terminals in MMA
mode while the welding output is not in use, to reduce the risk
of electric shock from the live output voltage. The disadvantage
of this system is that it makes the striking of the arc more dicult,
especially on restarts and with some types of electrode such as
low hydrogen electrodes.

TIPS & TRICKS

Duty Cycle Rating

Welding duty cycle is the percentage of actual welding time that
can occur in a ten minute cycle. E.g. 20% at 160 amps - this means
the welder can weld at 160 amps for 2 minutes and then the unit
will need to be rested for 8 minutes.

All duty cycle ratings are based on an ambient air temperature of
40°C with 50% humidity, which is the international standard for such
a rating. In an environment with temperatures exceeding 40°C, the
duty cycle will be less than stated. In ambient temperature less than
40°C, duty cycle performance will be higher.
