INSTRUCTION MANUAL FOR CAPACITOR DISCHARGE WELDING MACHINE
IMPORTANT: BEFORE STARTING THE EQUIPMENT,
READ THE CONTENTS OF THIS MANUAL, WHICH MUST
BE STORED IN A PLACE FAMILIAR TO ALL USERS FOR
THE ENTIRE OPERATIVE LIFE-SPAN OF THE MACHINE.
THIS EQUIPMENT MUST BE USED SOLELY FOR WELD-
ING OPERATIONS.
1 SAFETY PRECAUTIONS
WELDING AND ARC CUTTING CAN BE HARMFUL TO
YOURSELF AND OTHERS. The user must therefore be edu-
cated against the hazards, summarized below, deriving from
welding operations. For more detailed information, order the
manual code 3.300.758
ELECTRIC SHOCK - May be fatal.
· Install and earth the welding machine according to
the applicable regulations.
· Do not touch live electrical parts or electrodes with
bare skin, gloves or wet clothing.
· Isolate yourselves from both the earth and the workpiece.
· Make sure your working position is safe.
FUMES AND GASES - May be hazardous to your health.
· Keep your head away from fumes.
· Work in the presence of adequate ventilation, and
use ventilators around the arc to prevent gases from
forming in the work area.
ARC RAYS - May injure the eyes and burn the skin.
· Protect your eyes with welding masks fitted with fil-
tered lenses, and protect your body with appropriate
safety garments.
· Protect others by installing adequate shields or curtains.
RISK OF FIRE AND BURNS
· Sparks (sprays) may cause fires and burn the skin;
you should therefore make sure there are no flam-
mable materials in the area, and wear appropriate
protective garments.
NOISE
This machine does not directly produce noise
exceeding 80dB. The plasma cutting/welding proce-
dure may produce noise levels beyond said limit;
users must therefore implement all precautions required by
law.
PACEMAKERS
· The magnetic fields created by high currents may
affect the operation of pacemakers. Wearers of vital
electronic equipment (pacemakers) should consult
their physician before beginning any arc welding, cutting,
gouging or spot welding operations.
EXPLOSIONS
· Do not weld in the vicinity of containers under pres-
sure, or in the presence of explosive dust, gases or
fumes. · All cylinders and pressure regulators used in
welding operations should be handled with care.

ELECTROMAGNETIC COMPATIBILITY
This machine is manufactured in compliance with the
instructions contained in the harmonized standard
EN50199, and must be used solely for professional pur-
poses in an industrial environment. There may be poten-
tial difficulties in ensuring electromagnetic compatibility
in non-industrial environments.
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE
FROM QUALIFIED PERSONNEL.
2 GENERAL DESCRIPTIONS
2.1
The machine has been designed and built for welding fer-
rous and non-ferrous threaded stud bolts, Ø 4. 5 and 6 mm.
This welding system uses the extremely rapid (2-3 ms) dis-
charge of a battery of capacitors, which allows the welding
of threaded stud bolts with contact point start-up.

2.3.1 Thermal protection

This machine is protected by a thermostat, which prevents
the machine from operating if the allowable temperatures are
exceeded. Under these conditions the fan keeps running
and the display will show error code E1.
