ionTig 200 Pulse PFC

NOTE:

Only the Iw of TIG or the welding current of MMA can be adjust when welding.

4.3 Argon Arc Welding Operation

4.3.1 TIG welding (4T operation)

The start current and crater current can be pre-set. This function can compensate the possible

crater that appears at the beginning and end of the welding. Thus, 4T is suitable for the welding of

medium thickness plates.

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： Striking success, adjustment range of start current: 5~180A（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 off, the output current is the welding current(Iw);
