monoTIG 220ip / 220ipw / 220ip AC-DC / 220ipw AC-DC
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.
Ramp Time
Transition from the initial current to the welding current occurs within the specified time.
Setting range is 0 - 10 sec.
Main Current
Actual current at which the welding will be made. Adjustable between 3-220 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 1 ms and 50 A in 99ms for
100 ms 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- 2000 Hz. The default factory setting
is 5 Hz. and will be adjusted according to the workpiece thickness or the user request.
Repair 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
Repair current is only used in 4 trigger modes. By pressing and pulling the trigger, welding
is started. The trigger is pressed again and the repair 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.
End Ramp Time
When terminating the welding, the transition time from the main welding current to the
end current is set. Allows adjustment between 0-10 sec.
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.
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.
