1. Digital Ammeter / Parameter meter
The digital Ammeter is used to display the actual output current of the power source. It is
also used to display Parameters in Programming Mode.
Depending on the Programming Parameter selected, the status indictor adjacent to the
Ammeter will illuminate to show the units of the programming parameter.
When welding, the Ammeter will display actual welding current.
2. Power ON Indicator
The POWER ON indicator illuminates when the ON/OFF switch is in the ON position and
the correct mains voltage is present.
3. Thermal Overload Indicator Light
This welding power source is protected by a self resetting thermostat. The indicator will
illuminate if the duty cycle of the power source has been exceeded. Should the thermal
overload indicator illuminate the output of the power source will be disabled. Once the
power source cools down this light will go OFF and the over temperature condition will
automatically reset. Note that the mains power switch should remain in the on position
such that the fan continues to operate thus allowing the unit to cool sufficiently. Do not
switch the unit off should a thermal overload condition be present.
4.Peak Current
Setting ranges
10AMP to 200AMP (DC TIG and AC HF TIG mode), 30 to 170A (STICK mode)
17 This parameter sets the TIG WELD current. This parameter also sets the STICK weld
current.
5.Down Slope
Setting ranges 0-10s
This parameter operates in TIG modes only and is used to set the time for the weld current
to ramp down, after the torch trigger switch has been pressed to end current. This control
is used to eliminate the crater that can form at the completion of a weld.
6.Wave Balance
Setting arranges 10%-50%
This parameter operates in AC TIG mode and is used to set the penetration to cleaning action
ratio for the AC weld current. Generally WAVE BALANCE is set to 50% for AC STICK welding.
The WAVE BALANCE control changes the ratio of penetration to cleaning action of the AC TIG
welding arc. Maximum weld penetration is achieved when the WAVE BALANCE control is set to
10%. Maximum cleaning ofheavily oxidised aluminium or magnesium alloys is achieved when
the WAVE BALANCE control is set to 50%
AC Balance Control
Controls arc cleaning action. Adjusting the % EN of the AC wave controls the width of the
etching zone surrounding the weld.
Note:
Set the AC Balance control for adequate arc cleaning action at the sides and in
front of the weld puddle. AC Balance should be fine tuned according to how heavy or
thick the oxides are.
Wider bead, good penetration
ideal for buildup work
