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.  Di

culties  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.

LF Declaration

Consult  the  data  plate  on  the  equipment  for  the  power 
supply requirements.

Due to the elevated absorbance of the primary current from 
the  power  supply  network,  high  power  systems  a

ect  the 

quality  of  power  provided  by  the  network.  Consequently, 
connection  restrictions  or  maximum  impedance 
requirements permitted by the network at the public network 
connection point must be applied to these systems.

In  this  case  the  installer  or  the  user  is  responsible  for 
ensuring  the  equipment  can  be  connected,  consulting  the 
electricity provider if necessary.

Materials and their disposal

The equipment is manufactured with materials, which do not 
contain  any  toxic  or  poisonous  materials  dangerous  to  the 
operator.

When  the  equipment  is  scrapped,  it  should  be  dismantled 
separating components according to the type of materials.

Do  not  dispose  of  the  equipment  with  normal  waste.  The 
European  Directive  2002/96/EC  on  Waste  Electrical  and 
Electronic  Equipment  states  the  electrical  equipment  that 
has reached its end of life must be collected separately and 
returned to an environmentally compatible recycling facility. 

Handling of Compressed gas cylinders and 
regulators

All cylinders and pressure regulators used in welding 
operations should be handled with care.

Never allow the electrode, electrode holder or any other 
electrically “hot” parts to touch a cylinder.

Keep your head and face away from the cylinder valve outlet 
when opening the cylinder valve.

Always secure the cylinder safely

Never deface or alter any cylinder
