Introduction ：
-0: Press and hold the gun switch, Electromagnetic gas valve is turned on. The shielding gas starts to
ow.
- 0〜t1: Pre ow time, adjustment range of pre ow time :0.1~1.0S.
- t1 ： Striking success, adjustment range of start current: 5~200A.
- 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
0~10.0S.
- 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 o , 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: 0~10.0S.
- t5〜t6 ： Crater current holds time; adjustment range of crater current: 5~200A.
- t6 ： Loosen the gun switch, stop arc, and keep on argon owing.
- t6〜t7 ： Post ow time, adjustment range of post ow time: 0.1〜10.0S.
- t7 ： Electromagnetic valve is closed and stop argon owing. Welding is nished.
