ionTig 200 Pulse PFC

 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: 5~180A (200A);

 t6： Loosen the gun switch, stop arc, and keep on argon flowing;

 t6～t7： Post flow time, adjustment range of post flow time: 0.0～10.0S;

 t7： Electromagnetic valve is closed and stop argon flowing. Welding is finished.

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 :0.0~2.0S;

 t1～t2： Striking success, the output current slopes up to the setting current from minimum

current (5A); if the output pulse function is turned on, the slope up current is pulsed;

 t2～t3： During the whole welding process, the gun switch is pressed and held without

releasing;

 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;

 t3： Loosen the gun switch, the output current slopes down; if the output pulse function is

turned on, the slope down current is pulsed;

 t3～t4： The output current slopes down to minimum current (5A), stop arc; adjustment range

of down slope time: 0~10.0S;
