knob (#8) to 100 amps. Now, when you fully depress the
foot pedal, the maximum amperage will be 100 amps. This
makes the foot pedal less sensitive and makes it easier to
control your puddle.
When the remote/local switch is set to local, the amperage
will be adjusted by the amperage adjustment knob (#8) on
the front of the welder.
10) Lift Arc/HF Switch
When the lift arc/HF switch is in the HF position, the arc is
initiated by a high frequency pilot arc which allows the arc
to start without bringing the tungsten in contact with the
work. When the foot pedal is depressed, a high frequency
arc will jump from the tungsten to the ground, initiating the
arc. This makes it very easy to start the arc.
When the lift arc/HF switch is in the “Lift Arc” position, the
arc is initiated by touching the tungsten to the work and then
lifting it off the work. The lift arc mode allows you to
initiate the welding arc without high frequency. This is
important in any environment where the high frequency arc
will cause interference with sensitive electrical components
or computers. A good example of this would be stainless
steel repair in hospitals.
To TIG Weld using the Lift Arc Mode, simply touch the
tungsten to the workpiece, activate the torch trigger or
depress the foot pedal and lift off. When the tungsten breaks
contact with the work, the arc will start. You can also use
this method for Stick welding with the added benefit of
being able to vary your amperage with the foot pedal.
11) Pulse
Turning the “PULSE” knob from the off position to any
setting will allow you to do “pulsed TIG welding”. The
machine will pulse from whatever amperage you are welding
at to the what ever the final current is set to.
For example, if the local/remote switch is set to local, and
the amperage adjustment knob (#8) is set to 100 amps, and
the final current knob #5 is set to 50%, then the machine
will pulse between 100 and 50 amps. By adjusting the pulse
frequency from .5 Hz to 300 Hz determines how often this
happens. If it is set to 1hz, then the unit pulses once every
second. If it is set to 300 Hz, then it will pulse between 100
and 50 amps 300 times a second.
To turn off the pulse mode, simply rotate the pulse knob
until the knob clicks into the off position.
