The operator should be properly trained to use the welding machine safely and
should be informed about the risks related to arc welding procedures, the
associated protection measures and emergency procedures.

may reach double the allowed limit.
An expert coordinator must use measuring instruments to determine the
existence of a risk and should take suitable protection measures as detailed in
5.9 of the “IEC TECHNICAL SPECIFICATION or CLC/TS 62081”.
- Do not weld on containers or piping that contains or has contained flammable
liquid or gaseous products.
- Do not operate on materials cleaned with chlorinated solvents or near such
substances.
