CAUTION
: Examine the following matters for preventing electromagnetic hazards.
Furthermore, examine the following matters again if any electromagnetic
hazard occurs.
▪
Large current that rapidly changes during welding flows to the welder and weldment,
and it may hinder nearby equipment by electromagnetic noise.
(1) Do not share the ground for the base metal and welder with the ground for other equipment.
(2) Firmly close and fix all the doors and covers of the welding power supply unit.
(3) Minimize the length of the welding cable.
(4) Lay the base metal side cable, holder and torch side cable alongside to each other.
▪
Measures to be taken when any electromagnetic hazard occurs include the
following.
(1) Change the welder grounding point.
(2) Space the affected equipment apart from the welding power supply unit, cables and welding work
area.
(3) Apply electromagnetic shielding to the entire welding work area.
Please consult with us, if the problem of electromagnetic hazard is not solved even after taking
measures stated above.
