Introduction:
(1)
0: Press and hold the gun switch, Electromagnetic gas valve is turned on. The shielding gas
stars to flow;
(2)
0
̚
t1: Pre-gas time (0.1~2.0S);
(3)
t1
̚
t2: Arc is ignited at t1 and then output the setting value of start current;
(4)
t2: Loosen the gun switch, the output current slopes up from the start current;
(5)
t2
̚
t3: The output current rises to the setting value (I
w
or I
b
), the upslope time can be
adjusted;
(6)
t3
̚
t4: Welding process. During this period, the gun switch is loosen;
Note : Select the pulsed output, the base current and welding current will be outputted
alternately; otherwise, output the setting value of welding current;
(7)
t4: Press the torch switch again, the welding current will drop in accordance with the
selected down-slope time.
(8)
t4
̚
t5: The output current slopes down to the crater current. The downslope time can be
adjusted;
(9)
t5
̚
t6: The crater current time;
(10)
t6: Loosen the gun switch, stop arc and keep on argon flowing;
(11)
t6
̚
t7: Post-gas time can be set by the post-gas time adjustment knob on the front panel
(0.0
̚
10S);
(12)
t7: Electromagnetic valve is closed and stop argon flowing. Welding is finished.
Pulse frequency (9)
Only be available when pulse mode is selected. Set the rate that the welding output alternates
between the peak and base current settings.
Duty Cycle (10)
Only be available when pulse mode is selected. Set the time proportion as a percentage
between the peak current and base current when using pulse mode. Neutral setting is 50%, the
time period of the peak current and base current pulse is equal. Higher pulse duty setting will give
greater heat input, while lower pulse duty will have the opposite effect.
