IP 23 IP 23
The welding power sources comply with the requirements set out in IEC 974--1
The symbol indicates that this power source is designed for use in areas where there is an
increased electrical hazard.
The enclosure class indicates the degree of protection against penetration by solid objects and
water. Equipment marked IP 23 is designed for in-- and outdoor use.
*)
When welding with max 100 A a 10 A slow--blow fuse is sufficient.
With 16 A slow fuse, max. 150 A, 20% duty cycle for MMA welding.
