2. OPERATING CONDITIONS
1. The device may only be operated by trained personnel within the technical
regulations. The manufacturer is not liable for damage caused by improper
use and operation. Only use original spare parts from ALFA IN for
maintenance and repairs.
2. The device complies with IEC 61000-3-12.
3. The welding machine is tested according to the standard for degree of
protection IP 23S, which protects against the intrusion of solids with a
diameter greater than 12 mm and protection against the intrusion of water
falling in a vertical to the oblique direction to a slope of 60˚.
4. Operating ambient temperature between -10 to +40 °C.
5. Relative humidity below 90% at +20 °C.
6. As high as 3000 meters above sea level.
7. Connecting more than one generator in series or parallel is prohibited.
8. The machine must be located so the cooling air can enter and exit through
the cooling vents without restriction. Care must be taken to ensure that no
mechanical particles, especially metal particles, are sucked into the
machine (e.g., during grinding). Cooling is driven by electronic temperature
automation.
9. For the welding machine, it is necessary to perform a periodic inspection
once every 6/12 months by an authorized employee according to EN
331500 and EN 050630 –see paragraph Maintenance and service tests.
10. An authorized person may only carry out all interventions in the
electrical equipment and repairs (disassembly of the mains plug,
replacement of fuses).
11. The manufacturer sets the welding machine to 230 V with a tolerance
range of 110 - 230 V ± 10 %, which allows the operation of the machine in
the mains ~230 V and ~110 V.
12. The relevant mains voltage and power supply must match the mains
plug.
CautionExtension cables must have conductors with cross-
sections larger than 3x2,5 mm2. Welder can be operated on a single-phase
power generator of 8 kVA (1x230V/50Hz) or more, with a voltage
stabilization of ± 15%. Generators with lower power can damage the
machine.
CautionIf the machine is transported from a colder place to a much
warmer location, moisture condensation might occur, particularly inside the
welder. This could decrease electrical strength and increase the likelihood of
