6 CONTROL PANEL
Slope down
The slope down function is used to control the time of the current decrease in
the weld termination process to avoid any pipes and/or cracks.
Pulse settings
In order to set a pulsed current, four parameters are required: pulse current,
background current, pulse balance and pulse frequency.
Pulse current
The higher of the two current values when using a pulsed current.
Pulse background current
The lower of the two current values when using a pulsed current.
Pulse balance
Pulse balance is the ratio between pulse current and background current in a
pulse cycle. In order to control the energy of the arc and the size of the weld
pool, pulse balance is adjustable by setting the percentage of the pulse current
in a pulse cycle.
For example: If the pulse balance is set to 50%, the time of the pulse current and
the background current will be distributed equally in the pulse cycle. If the pulse
balance is set to 90%, the time of the pulse current will be 90% of the pulse
cycle and the background current will only be 10%.
Pulse frequency
The amount of pulse cycles in a time period. The higher the frequency, the more
pulse cycles per time period. When the pulse frequency is set low, the weld pool
will have time to partially solidify between each pulse. If the frequency is set
high, a more focused arc can be obtained.
Remote min current
This is used to set the minimum current for the foot pedal. Is set in % of the set
current in the range from 0–99% in steps of 1%.
For example: If the current is set to 100 A and the remote min current function is
set to 20, the remote min current will be 20 A. If the current is set to 80 A and the
remote min current function is set to 50, the remote min current will be 40 A.

Foot pedal functions explanation

Foot pedal with 2-stroke using TIG torch trigger
In 2-stroke mode, with the foot pedal activated, press the TIG torch trigger switch (1) to start
the shielding gas flow and initiate the arc. The current slopes up to the set remote min
current. Use the foot pedal to adjust the current between the remote min current and the set
current value. Release the TIG torch trigger switch (2) to start to slope down the current and
terminate the arc. The shielding gas will continue to flow in order to protect the weld and the
tungsten electrode.
