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 WELDING OPERATIONS.
1. SAFETY PRECAUTIONS
WELDING CAN BE HARMFUL TO YOURSELF AND OTHERS. The user must be educated on the hazards summarized below,
deriving from welding operations. For more detailed information, order the manual.
ELECTRIC SHOCK - May be fatal.
Install and ground the welding machine according to the applicable regulations.
Do not touch live electrical parts or electrodes with bare skin, gloves or wet clothing.
Isolate yourself from both the ground and the workpiece.
Make sure your working position is safe.
FUMES AND GASES - May be hazardous to your health.
Keep 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 filtered 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 your skin; be sure there are no flammable materials in the area and wear appropriate protection.
NOISE
This machine does not directly produce noise exceeding 80dB. The plasma cutting/welding procedure may produce noise
levels beyond said limit; users must 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 pressure, 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 and must be used
solely for professional purposes in an industrial environment. There may be potential difficulties in ensuring electromagnetic compatibility in non-industrial environments.
IN CASE OF MALFUNCTIONS, REQUEST ASSISTANCE FROM QUALIFIED PERSONNEL.

3. INSTALLATION
3.1 SETUP
Place the machine in a ventilated area.
Dust, dirt, or any other foreign material that may enter the machine can restrict ventilation which could affect the machine’s performance.
3.2 INPUT POWER CONNECTIONS
All sections concerning the installation of this machine must be read carefully.
This machine must be installed by skilled personnel.
Make sure that the input power plug has been disconnected before inspecting, maintaining, or servicing.
Connect the yellow-green wire to a good electrical ground.
Do not use water pipes as a ground conductor.
After a final inspection, the machine should be connected to the input supply voltage marked on the input power cord.
Mount a plug on the power supply cable that corresponds to the input power drawn by the machine.
3.3 CONNECTING the work return lead clamp
Attach the work return clamp to the work to be welded.
Make sure the ground clamp is tightly fastened to the work return cable and periodically check this connection remains
well tightened. A loose connection can cause weld current drops or overheating of the work return lead and clamp, which
creates the risk of burns from accidental contact with the work return lead. The weld circuit must not be placed deliberately in direct or indirect contact with the ground conductor.
If the work to be welded is attached deliberately to the ground by a protection lead, then the connection must be the most
direct possible and must be done using a lead that has a cross section that is at least equal to the cross section of the
work return lead being used for the weld circuit. The protection lead must also be attached to the work at the same spot as
the work return lead. To do so, a second ground clamp, fitted to the protection lead, must be attached next to the ground
clamp of the work return lead.
NOTE:
Small cross section and long extension cable will reduce the output current.
