Safety measures
Before using the machine, the following rules have to be observed:
 Ensure the appropriate working conditions for the welder. At the work area no inflammable
substances may be presented. Reconciliation of dust and other substances that prevent the
isolation of the device must be removed.
 Back up the welder properly when working outdoors.
 If you notice any overheating or smoke, fire, find strange sounds and unusual vibrations, you have
to switch off the machine immediately and disconnect it from power. In such cases the device has
to be inspected by an expert.
 In the event of a power outage, or when you realize power on the housing of the device, switch off
the machine immediately and disconnect it from power. The same applies in the case of
mechanical damage.
 Too high humidity in the work area can reduce the insulation class and cause a short circuit.
 During welding some parts of the machine exceeds 100 °C. Therefore these parts are protected
with a thermostat. Whenever you will notice any overheating, you have to turn off the power
immediately.

Use environment:
The device is not suitable for bathrooms, showers, swimming pools or similar areas. If it’s
necessary to work in these environments, you have to ensure that water can’t damage the
machine. The welding equipment isn’t suitable for use in rain or snow!
 The welding equipment can’t be used in areas, where it is exposed to shock or vibration. Areas that
should be avoided necessarily are for example, road-, rail- and cable handling equipment, aircraft,
water crafts, cranes and parts of machine tools.

Dust and cooling system:
The device has to be positioned in a way that sufficient air can flow through the cooling fins and the
cooling channels. The unit adjusts the cooling system automatically! Please pay attention, that no
metal dust can be sucked.

Stability:
The unit can be installed on up to 15° tilted planes. If the plane is tilted steeply, the welding
equipment can overturn!
