START-UP

1. Switch on the machine (Ref. 11 - Picture 1 Page 5., Ref. 23.1
- Picture 2 Page 5., - Picture 3 Page 5.)
2. Set the power switch (Ref. 23 - Picture 1 Page 5., - Picture
2 Page 5., - Picture 3 Page 5.) to an intermediate position.
3. Remove the nozzle and wire guide tube from the torch, press
the button (Ref. 8 - Picture 4 Page 6.) and feed the wire until
it protrudes from the front section of the torch. While feeding
wire through the torch, use the handwheel to adjust the force
that the wire pressure roller exerts on the feed roller; the set-
ting must ensure that the welding wire moves regularly with-
out slipping on the rollers and without deforming. Fit the torch
with a suitable wire guide tube according to the type of wire
used.
4. Secure the wire guide tube, and ensure that the diameter cor-
responds to the wire used.
5. Refit the gas nozzle.
6. Open the gas cylinder valve.
7. Connect the ground clamp to the workpiece on a section free
of rust, paint, grease or plastic.
