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 environment with tempera-
tures exceeding 40°C, the duty cycle will be less than
stated. In ambient temperature less than 40°C, duty
cycle performance will be higher.
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
lightly resting the tungsten on the work piece, ac-
tivating the torch trigger switch and then lifting the
tungsten 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.
Water Cooling
The ADVANCEMIG 500 is supplied standard with wa-
ter cooled MIG torch and water cooling interconnect
cable as suitable for up to 500A MIG welding. The
standard trolley package includes the integrated wa-
ter cooler.
The correct coolant to use is a mixture of Mono Pro-
pylene Glycol and water in a 1:3 ratio (25% propylene
glycol). Pure water may be used as a coolant liquid,
though it is not recommended for the long term reli-
ability of the water cooling system as it does not have
the lubrication properties of glycol and does not pro-
vide protection against freezing. Ready to use coolant
fluid can be purchased from authorised Strata deal-
ers.
WARNING!
Do not operate a water cooled torch
without the cooling system operating!
The ADVANCEMIG 350 is supplied standard with air
cooled MIG torch and standard interconnect cable.
The trolley package does not include water cooler.
