Auto Switch Specifications
• Lead wire — Oilproof heavy-duty vinyl cable, ø6, 0.5 mm
• Impact resistance — 1000 m/s
• Insulation resistance — 50 M or more at 500 VDC Mega (between lead wire and case)
• Withstand voltage — 1000 VAC for 1 minute (between lead wire and case)
• Ambient temperature — –10 to 60C
• Enclosure — IEC529 standard IP67, JIS 0920 waterproof structure
Magnetic Field Resistance
If the current of the AC welding machine is 16,000 A or lower, the switch can be used, even if the
distance between the welding conductor (gun cable) and the cylinder or switch is 0 mm.
Please contact SMC when the AC welding current exceeds 16,000 A.
