Touch Sense Ignition

The Touch Sense Ignition (TSI) function minimizes spatter and stabilizes the arc immediately after ignition.

In standard ignition the filler wire touches the workpiece and creates a short circuit.

The following describes how TSI operates in ON, Auto and OFF modes.

TSI ON

1.

The filler wire is fed forward until it touches the workpiece.

2.

The filler wire is retracted until the short circuit is broken and the arc is ignited immediately.

TSI Auto

1.

The filler wire is already in contact with the workpiece upon ignition (this is a prerequisite for TSI to work).

If the filler wire is not in contact with the workpiece, standard ignition is performed.

2.

The filler wire is retracted until the short circuit is broken and the arc is ignited immediately.

TSI OFF

1.

Standard ignition is performed.
