- Page 22 5-5. Electrical Service Guide Elec Serv 2014−01 NOTICE − INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of input power at rated frequency(+10%) and voltage (+10%). Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a genera- tor with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.
