Fixing sheet metal parts (tacking)

Body sections frequently have to be fixed temporarily for the purpose of alignment. In some areas,
clamps cannot be used.
In such cases, the sections can be fixed by tack welding with the MULTISPOT MI-100control.
Washers from which ¼ has been cut out can be used as fixing aid.
1. Insert contact piece U-B for washers into welding gun to
limit stop.
2. Cut off approx. ¼ of a washer of 8 mm Ø with a side
cutter.
3. Insert prepared washer into contact piece.
4. Select "washer weld" and sheet thickness on display.
5. Position the washer and press-on.
6. Press and keep hold of release button of the gun until end
of automatic welding program.

Water-cooled spot welding gun (special accessory)

The water-cooled spot welding gun can only be used for one-sided spot welding (push spots)!
1. Insert spot welding gun in the central socket of the welder unit. (Unit changes over
automatically to the right gun symbol).
2. Connect the cooling water feed pipe and return pipe to the corresponding connections of the
welder unit.
3. Clamp the copper ground lug to the body.
Caution: ensure there is good current conduction!
4. Proceed with spot welding as described in 6.9.1
5. Instead of the ground lug, a second gun can be connected (switch welder unit off first and
wait until cooling pump switches off automatically) so that 2 spot welds can be carried out at
once. This is useful, if the ground lug cannot be fitted. The welding procedure can only be
triggered with one gun.
6. After finishing the welding task, let the cooling pump run on for a while to prevent heat
congestion.
