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

：
Press and hold the gun switch, Electromagnetic gas valve is turned on. The shielding gas stars to
flow;

t2
：
Arc is ignited at t1 and then output the setting value of start current;

t2
：
Loosen the gun switch, the output current slopes up from the start current;

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;
