up the machine. Set the welding mode switch
(6) to 'Lift TIG' .

current control knob (9). You are now ready to
weld!
NOTE: The WF-200MST is a DC (Direct Current)
output welder only, this means that it is unable to
TIG weld reactive metals such as Aluminium alloys
and Brass (which require AC output). DC TIG output is
suitable for steel, stainless steel and copper. The New
Model is the model in the range that is designed for
TIG welding Aluminium and its alloys.

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° with 50% humidity, which is the international
C
standard for such a rating. In an environment with
temperature s exceeding 40°
be less than stated. In ambient temperature less
than 40° , duty cycle performance will be higher.
