1.3.2.2 SPOT Instruction

1 Spot Welding Application Using an Air Gun
1.3 Teaching
This instruction starts the spot welding sequence. It outputs the gun
pressure signal then executes the welding sequence appropriate for the
gun type. The function key [SPOT] can be used for its registration.
The condition number used for the registration of the spot instruction is a
value set on the manual spot condition window.
Two guns can be controlled simultaneously.
Under two-gun control, this instruction is completed when
the gun with the slower welding sequence completes weld-
SUPPLE-
ing. See chapter 1.6 Spot Gun Motion Control for informa-
MENT
tion on the welding sequence executed by this instruction.
