The supply voltage should be:
• For 1ph: 230 V AC ±10% or 120 V ±10%
• For 3ph: 460 V AC ±10% or 575 V ±10%
Too low supply voltage may cause poor welding performance. Too high supply voltage will
cause components to overheat and possibly fail. Contact the local electric utility for
information about the type of electrical service available, how proper connections should be
made, and inspection required.
The welding power source must be:
• Correctly installed, if necessary, by a qualified electrician.
• Correctly earthed (electrically) in accordance with local regulations.
• Connected to the correct size power point and fuse as tables below.
NOTE!
Use the welding power source in accordance with the relevant national regulations.
