FIRE AND EXPLOSION RISKS
Protect the entire welding area. Compressed gas containers and other inflammable material must be moved to a minimum safe
distance of 11 meters.
A fire extinguisher must be readily available. Be careful of spatter and sparks, even through cracks.
It can be the source of a fire or an explosion.
Keep people, flammable objects and containers under pressure at a safe distance.
Welding of sealed containers or closed pipes should not be undertaken. If opened, the operator must remove any inflammable or explosive materials
(oil, petrol, gas).
Grinding operations should not be directed towards the device itself or any flammable materials.
ELECTRIC SAFETY
The machine must be connected to an earthed electrical supply. Use the recommended fuse size.
An electrical discharge can directly or indirectly cause serious accidents, if not deadly.
Never touch live parts inside and outside of the device when it is on (Torches, clamps, cables, electrodes) as they are connected to the welding circuit.
Before opening the device, it is imperative to disconnect it from the grid and wait 2 minutes so that all the capacitors are discharged.
Do not touch the torch or electrode holder and earth clamp at the same time.
Be sure to change the cables and torches if they are damaged, to be performed by qualified and authorised personnel.
The dimensions of these accessories should be sufficient.
Always wear dry clothes in good condition, in order to be insulated from the electrical circuit. Wear insulating shoes, regardless of the environment
in which you work in.
TRANSPORTATION OF THE MACHINE
It is preferable to drain the cooling unit before transport.
Do not place/carry the unit over people or objects.
INSTALLATION
Rules to follow:
• Put the machine on the floor (maximum incline of 10°.)
• Ensure the work area has sufficient ventillation for welding, and that there is easy access to the control panel.
• The machine must be placed in a sheltered area away from rain or direct sunlight.
• The machine must not be used in an area with metal dusts.
• The machine protection level is IP23, which means :
- Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protection against the rain inclined at 60% towards the vertical.
These devices can be used outside in accordance with the IP23 protection index.
The manufacturer does not incur any responsibility regarding damages to both objects and persons that result from an incorrect
and/or dangerous use of the machine .
MAINTENANCE / RECOMMENDATIONS
Maintenance should only be carried out by a qualified person.
Ensure the machine is unplugged, and that the ventilator inside has stopped before carrying out maintenance work. High
Voltage and Currents inside the machine.
• Remove the casing 2 or 3 times a year to remove any excess dust. Take this opportunity to have the electrical connections checked by a qualified
person, with an insulated tool.
• Regularly check the condition of the power supply cable. If the power cable or connection cables are damaged, they must be replaced by the
manufacturer, its after sales service or an equally qualified person to prevent danger.
• Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
The cooling liquid must be changed every 12 month in order to avoid sediments which could block the torch cooling circuit. Any
leak or residual fluid after use, must be handled within the appropriate purification factory. If possible, recycle the product. It
is prohibited to empty the product into a river, sceptic tank or a draining system. The diluted fluid must not be emptied in the
sewers, unless authorised by the local regulations.
