12
Gas Check Switch
It is for checking the flow of the gas. If this switch is ON, then the gas is flowed
by opening the solenoid valve inside the machine.
13
Pulse Width Control
It controls the pulse width
14
Pulse Frequency Control
It controls the pulse frequency. If the low pulse selected at the pulse frequency
selection switch, apply the inside circle 0.5-25Hz or if the high pulse selected,
apply the outside circle 10-500Hz.
15
Pulse Frequency selection switch
It choose the pulsed TIG (Low pulse, High pulse) or non pulsed TIG.
When compared with non pulsed TIG welding performed at the same average
current, the pulsed TIG get better results smaller heat affected zone, fewer
deformations and reduced chance of cracking and gas entrapment.
16
Crater current control
It controls the crater current. It is important to get the good welding quality.
17
Down slope time control
It controls the time to reach to the crater current from the welding current. It is
important to carefully control the downslope of current to get the good welding
bead.
18
Cooling mode selection switch
It choose the cooling mode "WATER COOL" or "AIR COOL"
19
Gas after flow time control
The output current of the machine will turn OFF and then the gas valve will
remain open to continue the flow of the gas. It adjusts the duration of this
after-flow time.
20
Cleaning width control
It is for getting the better welding bead when AC TIG welding.
21
AC TIG / DC TIG selection switch
AC TIG should be selected if aluminum would be welded.
