12、ing significant technical changes with respect to EN 60974-5:2002: changes induced by the publication of EN 60974-1:2005; EN 60974-5 is not applicable to spool-on torches that EN 60974-7 covers (see Clause 1); EN 60974-5 is not applicable to wire feeders which are designed for use by laymen that EN
13、60974-6 covers (see Clause 1); wire feeders with degree of protection IP23S may be stored, but are not intended to be used outside during precipitation unless sheltered (see 6.2.1 and Table 1); withdrawal of voltage limitation for input supply network (see 6.4); protective connection provision for w
14、elding circuit (see 6.5); addition of tilting stability (see 10.5); clarification of the definition of the thermal requirement test. The manufacturer gives the maximum load (see Clause 9); introduction of rating plate layout for stand-alone wire feeder (see 11.2); introduction of new combined symbol
15、s for liquid/gas input and output based on EN 60974-1 (see 13.2). This standard is to be used in conjunction with EN 60974-1:2005 and EN 60974-7:2005. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard
