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 sufficiently 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 weld-
ing that removes the need to ‘scratch’ start or strike
the tungsten on the work piece to start the arc, which
can have a negative effect 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 off. 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 weld-
ing output is not in use, to reduce the risk of electric
shock from the live output voltage. The disadvan-
tage of this system is that it makes the striking of
the arc more difficult, especially on restarts and with
some types of electrode such as low hydrogen elec-
trodes. VRD protection is enabled standard for the
AdvanceArc 160/200. If it is not required, the feature
can be disabled by a Strata service dealer.
Tips & Tricks
Duty Cycle Rating
Welding duty cycle is the percentage of actual weld-
ing 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 envi-
ronment 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.
