2- Trigger Modes / Hot Start - Arc Force Selection
You can switch between 2/4 trigger and Spot modes with the touch-sensitive button while the
TIG modes are selected you can also change Hot Start and Arc Force settings while the electrode
modes are selected.
Ht
Machine provides up to 2 times higher current than main current for easy ignition.
• Hot Start will be set between 0-100% with the help of the current adjustment pot.
• If set to 0, it does not add any value on the main current at the first ignition, if set to 100
it adds a value increased by 100% on the main current.
• In miliseconds it reduces the amperese to main welding current.
• Factory setting is 20 %.
Ar
When welding the electrode, it prevents the arc interruption by increasing the current up
to twice the main welding current in case the arc tends to interrupt.
• Arc Force is between 0-100 %.
• Arc Force prevents the electrode from sticking by adjusting the current when the
electrode tends to stick.
• The default factory setting is 20 %.
In 2-Trigger mode;
• Welding starts when the trigger is pressed, pre-gas is supplied ignites at minimum
current, makes the launch ramp and continues welding in main current.
• When the trigger is released, it makes the end ramp, fills the crater in the crater filling
current, makes the final gas time and completes the welding.
In 2-Trigger Mode, the TIG Curve operates as follows;
• The initial gas time can be set from 0 sec to 20 sec. Factory default setting is 1 sec.
• The initial current (initial ignition current) is 30% of the main current.
• Up ramp time is between 0-10 sec. This determines the ramp from the ignition current
to the main current.
• The end ramp determines the time from the main current to the end current. The end
current is 30% of the main current.
