8.3.6 Tandem for LAF and TAF power sources
Used when welding with two welding heads.
Position the cursor on the TANDEM row and press ENTER. Select ON, using the positioning
knob and press ENTER.
In order to weld with two welding heads, the WELD HEAD OFFSET function must be set.
WELD HEAD OFFSET is the distance in millimetres between the welding heads.
When you specify the distance between welding head 1 HEAD and welding head 2 TAIL, the
value is recalculated by the control unit to a time between when welding head 1 starts and
welding head 2 is to start.
The time that the control unit can calculate for the distance between the starting and stopping
of the welding power sources is a maximum of 65 seconds. This means that if, for example,
50 cm/min is specified, 2000 mm can be entered as the maximum WELD HEAD OFFSET.
This is so that time does not expire before welding head 2 reaches the start point.
TAIL HEAD
WELD HEAD OFFSET
NOTE!Ensure that both control units have the same settings for WELD HEAD OFFSET and
specify the same travel speed. The ”Master” control unit must be allocated HEAD and the
”Slave” control unit TAIL. Travel motion is always controlled from ”Master”.
