Ramp Time
Transition from the initial current to the welding current occurs within the specified time. Setting range is 0.1-10 sec.
Main Current
Actual current at which the welding will be made. Adjustable between 0-220 Amperes.
Frequency Amplitude
It is active when the pulse mode is selected. Determines the amplitude ratio between low current and high current in a
pulse cycle. Indicates how long the set high current will be active within 1 period. Default factory setting is set to 50%.
Allows setting between 1-99%. Low current is pit current and high current is main current.
For example; when the duty cycle is set to 1%, let the main current be 100 A and the pit current be 50 A so this indicates
that it will operate at 100 A in 1ms and 50A in 99ms for 100ms period.
Pulse Frequency
It is active when the pulse mode is selected. In pulse mode it determines the frequency of a pulse cycle consisting of
welding current and low current. It can also be specified as the number of pulses per second. Allows setting from 0.1 to
2 KHz. The default factory setting is 75 Hz. and will be adjusted according to the workpiece thickness or the user request.
Pit Current
Adjusted in terms of %. Occurs below the specified % of the main current. •It is used to correct errors during the welding
process. Allows setting between 1-99%. It used only with the multi-function torch. Determines low current when pulse
mode is active.
Note
Pit current is only used in 4 trigger modes. By pressing and pulling the trigger, welding is started. The trigger is pressed
again and the pit current value is used during the time it is pressed. When you release your finger from the trigger,
you can return to normal current and continue welding process. If you press and pull the trigger shortly, welding will
terminate.
Spot Time
The welding will continue during the period specified at spot mode and the welding will stop at the end of that period.
Setting range is 0.1-20 sec.
End Ramp Time
When terminating the welding, the transition time from the main welding current to the end current is set. Allows
adjustment between 0.1-10 sec.
Crater Filling (Final Current)
When ending the welding, switches to the end current from the main welding current. In this current, welding seam is
corrected and welding is terminated.
Note
Initial Current - Ramp Time - Main Current relation: The adjusted start current will be lower than the main current value.
The arc starts with the initial current and the main current will gradually be increased during the set ramp time. This
extends the service life of the tungsten tip and provides a more stable arc start.
Final Gas
After the welding is terminated, the shielding gas continues to flow for the time set. By this means, the life of the
tungsten tip is extended by cooling and at the same time the welding pool is protected until it cools. Allows adjustment
between 0 - 20 sec.
