3. TIG Mode Parameter Adjustments
3.1. Pre-Flow
Indicates the gas flow prior to arc start. Pre flow duration is adjustable from 0s to
10s.
3.2. Start Amps:
Indicates the startup amperage adjustable from 10A to approximately 300A when
the trigger is pressed. It serves to preheat the material.
3.3. Up Slope
Indicates the time from the arc-start up to the preset power level. It is adjustable
between 0.1 and 5s.
3.4. Peak Amps
In the pulsed welding mode, the peak current is high and can melt the welding wire
and the weld pool to form a welding seam. Also called pulse current, it can be
adjusted between 10A and approximately 300A.
3.5. Base Amps
The lower amperage for each pulse is set. It not only serves arc maintenance but
also arc stability and assists preheating of the following weld pool. Base Amps are
adjustable between 10A and 300A.
3.6. Duty Cycle
It expresses the percentage each pulse cycle spends at peak amperage per second.
The wider the pulse, the larger the weld pool of the welding seam and vice versa.
Duty cycle is adjustable between 20% and 80%.
3.7. Pulse Frequency
Refers to the number of pulse cycle changes per second per unit time and is
adjustable between 0.5Hz and 100Hz.
