Introduction
：

0
：
Press and hold the gun switch, Electromagnetic gas valve is turned on. The
shielding gas starts to flow;

0
～
t1
：
Pre flow time, adjustment range of pre flow time :0~1.0S;

t1
：
Striking success, adjustment range of start current: 5~160A
（
200A
） ；

t2
：
Loosen the gun switch, the output current slopes up from start current; if the output
pulse function is turned on, the output current is pulsed;

t2
～
t3
：
Output current slopes up to the setting current value; adjustment range of up slope
time 0~5.0S ;

t3
～
t4
：
Welding process. During this period, the gun switch is loosen;
Note: If the output pulse function is turned on, the output current is pulsed. If the output pulse
function is turned off, the output current is DC current;

t4
：
Repress down the gun switch, the output current slopes down to crater current; if the
output pulse function is turned on, the slope down current is pulsed;

t4
～
t5
：
Down slope time, adjustment rang of down slope time: 0~5.0S;

t5
～
t6
：
Crater current holds time; adjustment range of crater current: 5~160A (200A);

t6
：
Loosen the gun switch, stop arc, and keep on argon flowing;

t6
～
t7
：
Post flow time, adjustment range of post flow time: 3.0
～
10.0S;

t7
：
Electromagnetic valve is closed and stop argon flowing. Welding is finished.
