ATTENTION:
The following user manual should be read prior installing and starting
the device. OSH manual should be known to every welder and employee responsible
for equipment maintenance.
PRELIMINARY REMARKS
Commissioning and normal operation are possible only after carefully reading the following
manual. Arc welding requires compliance with the requirements for electric arc welding and fire
regulations. The welder should be supplied with protective clothing and equipment in
accordance with current regulations. It is necessary to use a set of personal protective
equipment (PPE) in accordance with provisions of the Council Directive 2016/425/EEC. The
personal protective equipment includes: welding mask with a protective filter, welding gloves,
protective apron, welding clothing, and leather shoes. Despite the high technical standard of
the device, the personnel should represent considerable discipline in approach to health and
safety requirements to protect against harmful and health hazardous factors developed from
welding technology.
OPERATING CONDITIONS
This device can operate under severe conditions. It is however important to apply simple
preventive measures to ensure long and reliable work:
- do not place or use this device on an inclined surface (of more than 15º),
- do not use the device for pipe defrosting,
- the device must be located in a place where the free circulation of clean
air is ensured without any restriction of airflow to and from the fan. When the device is
connected to the network, do not cover it with, for example, paper or cloth;
- minimize the amount of dirt and dust that can get into the device,
- device housing has an IP21S protection. Keep it dry and do not place on
wet surfaces or in a puddle,
- do not use the device for welding the tanks previously used for storing flammable substances.
ENVIRONMENTAL CONDITIONS
Range of air temperatures for
- operation: from-10ºC to +40ºC
- storage and transportation: from -25ºC to +55ºC
- Relative air humidity: up to 50% at +40ºC; up to 90% at +20ºC.
GASES AND FUMES
TIG and MMA welding modes produce harmful gases and fumes containing ozone and
hydrogen as well as oxides or metal particles. Therefore, the welding work station should be
fitted with very good ventilation (dust and smoke extraction or airy location). Metal surfaces
intended for welding should be free from chemical contamination, especially degreasers
(solvents),
that decompose during welding process and produce toxic gases. Welding of galvanized,
cadmium-coated or chromium-plated parts is permitted only when a suction and filtering device
is fitted, and with introduction of fresh air to the welding work station.
