OPERATING MANUAL
7. Control Panel Details
AC TIG Mode
This indicates that the machine is in Alternating Current (AC) TIG mode.
When TIG welding in AC mode, the current supplied by the welding inverter operates with
a positive and a negative half cycle. This means current flows in one polarity and then to
the opposite polarity. The combination of one positive half cycle and one negative half
cycle is termed one cycle. You will need to AC TIG Mode when welding aluminium.
High Frequency TIG Mode
This indicates that the machine will use High Frequency to start the weld arc while TIG
welding. While using HF start, you do not need to touch the electrode to the workpiece,
just press the trigger button on the torch or depress the foot pedal and the arc will start.
Lift Arc TIG Mode
This indicates that the machine will initiate the arc by lifting the electrode off of the
workpiece.
DC TIG Mode
This indicates that the machine is in Direct Current (DC) TIG mode.
When TIG welding in DC mode the current supplied by the welding inverter operates
within a single polarity. You will need this mode to weld most other metal types other than
aluminium.
MIX TIG Mode
This indicates that the machine is in Mixed AC/DC TIG mode.
Mixed AC/DC welding is the combination of TIG AC and TIG DC- in one weld. Mixed AC/
DC gives you faster welding speeds, better penetration, and a faster weld puddle on cold
workpieces. Mixed AC/DC is ideal when welding thicker aluminium.
MMA 'Stick' Mode
This indicates that the machine is in Manual Metal Arc mode.
