Wear suitable protective flame resistant clothing. The sparks and spatter from welding, hot work pieces, 
and hot equipment can cause fires and burns. Welding on closed containers, such as tanks, drums, or 
pipes, can cause them to explode. Accidental contact of electrode to metal objects can cause arcs, 
explosion, overheating, or fire. Check and be sure the area is safe and clear of inflammable material 
before carrying out any welding.

Protection against noise

Some welding and cutting operations may produce noise. Wear safety ear protection to protect your 
hearing.

Protection from moving parts

When the machine is in operation, keep away from moving parts such as motors and fans. Moving 
parts, such as the fan, may cut fingers and hands and snag garments. Protections and coverings may 
be removed for maintenance and controls only by qualified personnel, after first disconnecting the 
power supply cable. Replace the coverings and protections and close all doors when the intervention 
is finished, and before starting the equipment. Take care to avoid getting fingers trapped when loading 
and feeding wire during set up and operation. When feeding wire be careful to avoid pointing it at other 
people or toward your body. Always ensure machine covers and protective devices are in operation.

Precautions against fire and explosion

Avoid causing fires due to sparks and hot waste or molten metal. Ensure that appropriate fire safety 
devices are available near the cutting / welding area. Remove all flammable and combustible materials 
from the cutting / welding zone and surrounding areas. Do not cut/weld fuel and lubricant containers, 
even if empty. These must be carefully cleaned before they can be cut/welded. Always allow the cut/
welded material to cool before touching it or placing it in contact with combustible or flammable 
material. Do not work in atmospheres with high concentrations of combustible fumes, flammable gases 
and dust. Always check the work area half an hour after cutting to make sure that no fires have begun.

Risks due to magnetic fields

The magnetic fields created by high currents may affect the operation of pacemakers or electronically 
controlled medical equipment. Wearers of vital electronic equipment should consult their physician 
before beginning any arc welding, cutting, gouging or spot welding operations. Do not go near welding 
equipment with any sensitive electronic equipment as the magnetic fields may cause damage.

RF Declaration

Equipment that complies with directive 2004/108/EC concerning electromagnetic compatibility (EMC) 
and the technical requirements of EN60974-10 is designed for use in industrial buildings and not those 
for domestic use where electricity is provided via the low voltage public distribution system. Difficulties 
may arise in assuring class A electromagnetic compatibility for systems installed in domestic locations 
due to conducted and radiated emissions. In the case of electromagnetic problems, it is the 
responsibility of the user to resolve the situation. It may be necessary to shield the equipment and fit 
suitable filters on the mains supply.
