• Take care of your own safety and the one of third parties by reviewing and strictly following the instructions, included in the operating manual of the device.

• Only qualied and skilled personnel can be allowed to start, operate, maintain and repair the machine.

• The machine must never be operated contrary to its intended purpose.

1.2 PREPARATION OF WELDING WORK SITE

WELDING OPERATIONS MAY CAUSE FIRE OR EXPLOSION

• Strictly follow the occupational health and safety regulations applicable to welding operations and make sure to provide appropriate re extinguishers at the welding work site.

• Never carry out welding operations in ammable places that pose the risk of material ignition.

• Never carry out welding operations in an atmosphere containing ammable particles or vapours of explosive substances.

• Remove all ammable materials within 12 meters from the welding operations site and if removal is not possible cover ammable materials with re retardant covering.

• Use safety measures against sparks and glowing particles of metal.

• Make sure that sparks or hot metal splinters do not penetrate through the slots or openings in the coverings, shields or protective screens.

• Do not weld tanks or barrels that contain or have contained ammable substances. Do not weld in the vicinity of such containers and barrels.

• Do not weld pressure vessels, pipes of pressurised installations or pressure trays.

• Always ensure adequate ventilation.

• It is recommended to take a stable position prior to welding.

• When welding, wear clean, oil stain free protective clothing made of non-ammable and non-conductive material (leather, thick cotton), leather gloves, high boots and protective hood.

• Before welding remove all ammable or explosive items, such as propane butane lighters or matches.

• Use facial protection (helmet or shield) and eye protection, with a lter featuring a shade level matching the sight of the welder and the welding current. The safety standards suggest colouring No. 9 (minimum No. 8) for each current below 300 A. A lower colouring of the shield can be used if the arc is covered by the workpiece.

• Always use approved safety glasses with side protection under the helmet or any other cover.

• Use guards for the welding operations site in order to protect other people from the blinding light radiation or projections.

• Always wear earplugs or another hearing protection to protect against excessive noise and to avoid spatter entering the ears.

• Bystanders should be warned to not look at the arc.

• The power cable must be connected to the nearest socket and placed in a practical and secure position. Positioning the cable negligently in the room and on a surface which was not checked must be avoided as it can lead to electrocution or re.

• Touching electrically charged elements can cause electrocution or serious burns.

• Electrical arc and the working area are electrically charged during the power ow.

• Input circuit and inner power circuit of the devices are also under voltage charge when the power supply is turned on.

• The elements under the voltage charge must not be touched.

• Dry, insulated gloves without any holes and protective clothing must be worn at all times.

• Insulation mats or other insulation layers, big enough as not to allow for body contact with an object or the oor, must be placed on the oor.

• The electrical arc must not be touched.

• Electrical power must be shut down prior to cleaning or electrode replacement.

• It must be checked if the earthing cable is properly connected or the pin is correctly connected to the earthed socket. Incorrect connection of the earthing can cause life or health hazard.

• The power cables must be regularly checked for damage or lack of insulation. Damaged cables must be replaced. Negligent insulation repair can cause death or serious injury.

• The device must be turned off when it is not in use.

• The cable mustn’t be wrapped around the body.

• A welded object must be properly grounded.

• Only equipment in good condition can be used.

• Damaged device elements must be repaired or replaced. Safety belts must be used when working at height.

• All tting and safety elements must be stored in one place.

• From the moment of turning on the release, the handle end must be kept away from the body.

• The chassis ground must be mounted to the welded element or as close to it as possible (e.g. to a work table). THE DEVICE CAN STILL BE UNDER VOLTAGE UPON FEEDER DISCONNECTION

• The voltage in the input capacitor must be checked upon turning off the device and disconnecting it from the power source. One must make sure that the voltage value is equal to zero. Otherwise, the device elements must not be touched.

• Always keep a certain distance from the gas outlet

• When welding, ensure good ventilation. Avoid inhalation of the gas.

USER MANUAL12 13 Rev. 23.05.2022 Rev. 23.05.2022

• Chemical substances (lubricants, solvents) must be removed from the surfaces of welded objects as they burn and emit toxic smokes under the inuence of temperature.

• The welding of galvanised objects is permitted only when efcient ventilation is provided with ltration and access to fresh air. Zinc fumes are very toxic, an intoxication symptom is the so called zinc fever.

3.3 CONNECTING THE DEVICE

3.3.1 Connecting the power

• Connection of the device must be performed by a qualied person. In addition, a person with required qualications should check if the earthing or electrical installation with protection system is in line with the safety regulations and if they operate correctly.

• The device must be placed near the work station.

• Connection of excessively long conduits to the machine must be avoided.

• One-phase welders should be connected to the socket tted with an earthing prong.

1. ERROR INDICATOR = The indicator lights in the following two situations:

a) If the machine has malfunctioned and cannot be operated. b) If the cutting device has exceeded the standard working time, the protection mode is initiated and the machine will stop functioning. This means that the machine is now being cooled in order to be able to restore the temperature control again after the device has overheated. Therefore, the machine is stopped. During this process, the red warning light on the front panel lights up. In this case it is not necessary to unplug the device. The ventilation system may be left on in order to enhance the cooling of the machine. When the red light goes dark, this means that the temperature is set to the normal level and the unit can be put back into operation.
