3.08 Mains Supply Voltage Requirements
The Mains supply voltage should be within ± 15% of the rated mains supply voltage. Too low a voltage may cause
poor welding performance. Too high a supply voltage will cause components to overheat and possibly fail.
The Welding Power Source must be:
• Correctlyinstalled,ifnecessary,byaqualiedelectrician.
• Correctlyearthed(electrically)inaccordancewithlocalregulations.
• ConnectedtothecorrectsizepowerpointandfuseaspertheSpecicationsonpage3-2,3-3and3-4.
The WeldSkill 250 MIG Power Source is supplied with a 20 Amp input lead and is designed for a 240 VAC supply
voltage.
