er Manual
● The end current (I-E) is as shown in the figure, which is used to fill the crater.
● The start current (I-S) is as shown in the figure, which is used to increase the heat input at the
start of welding to effectively avoid weld defects at arc striking. The duration of start current
only applies to the S2T operating mode.
● Burn-back time (BURN): It is used to adjust the ball effect at the end of welding.
● Spot welding time (SPOT): duration of spot welding.
● End time (T-E): duration of end current, which only applies to the S2T operating mode.
● Transient time (DWSL): switching time of current, such as the time between the start current
and welding current.
