CHECKS AND PREFARATIONS PRIOR TO OPERATION Attaching the welding wire ⑩Put back a pressure arm and pressure nut in that order. Attach a feed roller in direction which allows you to see the same numeral as the wire diameter used.
CHECKS AND PREFARATIONS PRIOR TO OPERATION Feeding the Wire by Inching Operation Hold Down the inching switch to feed the wire and release it when the wire comes out of the tip of the welding torch about 15 to 20 mm. Caution Feed a fine-diameter wire (0.9) slowly because it buckles easily.
WELDING BY MANUAL OPERATION The following two kinds of welding are allowed by operating the “CRATER ON/OFF” selector switch on the operation panel and the torch switch. Be sure to read “Duty cycle” on Page 22, and observe a duty cycle in using the equipment. Using only this switch allows start/stop operation.
WELDING BY MANUAL OFERATION Welding with crater control disabled (torch switch synchronous operation) This welding is mainly used for tack welding,, repeated short welding or thin-plate welding. Operation Procedure Set the CRATER “ON/OFF” selector switch to "OFF" and turn on/off the torch switch. Synchronized with it, welding arc starts or stops.
DUTY CYCLE 60%(387 A or less) Rating YD-500KR (Service Range) 60 100 Welding Current (A) A rated duty cycle 50% means to use the rated welding current for 5 minutes out of 10 minutes and suspend operation for remaining 5 minutes.
EXTENDED FUNCTIONS The extended functions refer to the altered and expended forms or various basic functions and performances set and specified upon shipment, including the basic welding control sequence described so far. Connecting the Extension Cable (Extension Cable is Optional) If an extension cable is connected between the plus(+)-side output terminal of the welding power unit and the output cable of the wire feeder, the scope of welding work can be expanded.
EXTENDED FUNCTIONS Switch and Controls on the Printed Circuit Board Tips When the front panel is removed, you can find various switches (connectors) and controls on the printed circuit board as well, which are available for extending many different functions. Caution After switching work is completed, be sure to put back the front panel as it was.

EXTENDED FUNCTIONS APPLICATIONS Selector Switch 10 (SIMPLE UNIFIED/INDIVIDUAL) --- Set to INDIVIDUAL upon shipment INDIVIDUAL --- This mode sets both welding current and voltage to INDIVIDUAL. SIMPLE UNIFIED --- When a welding current is selected with the output regulator on the remote controller, the SIMPLE UNIFIED mode takes place ,where an almost corresponding welding voltage is automatically set.
EXTENDED FUNCTIONS Adjusting the Controls on the Printed Circuit Board The following control functions are incorporated In this machine in order to improve weld ability. They will work regardless of the settlings/operations of various switches on the welding power unit operation panel. The incorporated control functions can he adjusted with the controls on the printed circuit board.
