Safety Precautions At The Installation Location; Safety Precautions In Normal Operation; Safety Inspection; Alterations To The Welding Machine - Fronius VARIOSTAR 357 Mode D'emploi

- In addition to the instruction manual, copies of both the generally
applicable and the local accident prevention and environmental
protection rules must be kept on hand, and of course observed in
practice.
- All the safety instructions and danger warnings on the welding
machine itself must be kept in a legible condition.
SAFETY PRECAUTIONS AT THE INSTALLATION
LOCATION
- The welding machine must be placed on an even, firm floor in such a
way that it stands firmly. A welding machine that topples over can
easily kill someone!
- Special regulations apply to rooms at risk from fire and/or explosion.
Observe all relevant national and international regulations.
- By means of internal instructions and checks, ensure that the work-
place and the area around it are always kept clean and tidy.
VAGRANT WELDING CURRENTS
- Ensure the workpiece clamp is connected tightly to the workpiece
- Set the welding machine up insulated where the floor conducts
electricity
If these instructions are not followed vagrant welding currents occur,
these can destroy earthed conductor terminals and other electrical
equipment.

SAFETY PRECAUTIONS IN NORMAL OPERATION

- Only operate the welding machine if all its protective features are fully
functional.
- Before switching on the welding machine, ensures that nobody can
be endangered by your turning on the machine.
- At least once a week, check the machine for any damage that may be
visible from the outside, and check that the safety features all function
correctly.

SAFETY INSPECTION

The owner/operator is obliged to have the machine checked for proper
condition by a trained electrician after any alterations, installations of
additional components, modifications, repairs, care and maintenance,
and in any case at least every twelve months.
In the course of such inspection, the following regulations must be
observed (as a minimum):
- IEC (EN) 60 974-1 - Arc welding equipment - Part 1: Welding power
sources
- VBG 4, §5 - Electrical plant and apparatus
- VBG 15, §33 / §49 - Welding, cutting and allied processes
- VDE 0701-1 - Repair, modification and inspection of electrical
appliances; general requirements
- VDE 0702-1 - Repeat tests on electrical appliances
Further information on corrective maintenance, modification and
inspection of welding machines is available from your regional or national
Fronius service centre,who will be pleased to provide you with a copy of
the Work Instruction "Safety Inspection of Welding Machinery" (AA-
PMÜ-01) upon request.

ALTERATIONS TO THE WELDING MACHINE

- Do not make any alterations, installations or modifications to the
welding machine without getting permission from the manufacturer
first.
- Replace immediately any components that are not in perfect condition.

SPARES AND WEARING PARTS

- Use only original spares and wearing parts. With parts sourced from
other suppliers, there is no certainty that these parts will have been
designed and manufactured to cope with the stressing and safety
requirements that will be made of them.
- When ordering spare parts, please state the exact designation and
the relevant part number, as given in the spare parts list. Please also
quote the serial number of your machine.

CALIBRATION OF WELDING MACHINES

In view of international standards, regular calibration of welding machin-
ery is advisable. Fronius recommends a 12-month calibration interval.
For more information, please contact your Fronius partner!

CE-MARKING

The welding machine fulfils the fundamental requirements of the Low-
Voltage and Electromagnetic Compatibility Directive and is thus CE-
marked.
