SUPPLY CONNECTIONS OF THE MACHINE The double or triple models supply voltage (for example: 220/ 440V~) are sent connected for the highest voltage. To change the connection, refer to the wiring diagram or connection that is glued on the inside of the access cover to the junction block on the top right side. Check the correct position according to the main voltage, cooper bridges and tighten of the nuts to avoid loosening the lock nut inside. Options junction arrangements:

Make sure that the voltage, phase and frequency of power supply is as specified on the name plate. A qualified electrician should connect the two - phase voltage to terminals L1 and L2 with a switch with fusible according to the supply voltage, which protrude from the back of the machine, according to the National Electric Code, state or local and in accordance with the wiring diagram located within the machine, on the inner side of the upper cover. The chassis of the welding machine must be grounded. For this purpose it provides a small terminal marked with the symbol located on the back cover of the machine. Connect this terminal to an effective ground (piping, structure or ground wire). Refer to the National Electrical Code, state or local details on proper methods grounding.
W A R N I N G ELECTRIC SHOCK can be mortal. • An electrician must install and give service to this equipment. • Turn off the machine from the fuse box before working on equipment. • Do not touch electrically live parts.
It is necessary to use for the electrode holder and the work clamp, electrode holder cable type, because the current is conduced by two lines. If for the ground connection is used another material that is not a good conductor (rods, slabs, etc.) It will lose energy and will decrease the output values due to the electrical resistance that these materials have, which considerably affect the quality of their work.

DUTY CYCLE This welder is rated for a duty cycle of 30% in AC. The duty cycle is based on a period of 10 minutes. Therefore, the welder can be operated with its rated output indicated on the nameplate for 3 minutes of each period of 10 minutes without overheating. During the rest period, the machine is connected to the line with idle working and the fan motor running.

MACHINE OPERATION

Make sure the machine is properly installed and that all fittings are properly connected before any operation.
MACHINE TURN ON The switch located on the top right of the control panel energizes the machine when it moves to the position I (“ON”).
OUTPUT CURRENT ADJUSTMENT The output amperage setting of the machine is done by the crank. Turning clockwise, the value of the output current increases. The amperage dial indicator, located at the center left of the front cover, shows an approximate value of the actual current obtained.
ADJUSTMENT AND CONTROL PANEL A) SWITCH LINE. Two-position switch that controls the input power of the machine. B) RANGE SELECTOR. Two-position switch that controls the high and low current range. C) POLARITY SELECTOR. 3 position switch that controls the polarity, allowing access to AC, positive and negative DC. D) CONTROL CRANK. Controls output current of the machine. Increases the value by turning clockwise and decreases by turning counterclockwise. E) CURRENT INDICATOR. Dial indicator of current that serves as reference to adjust the output current of the machine to an approximate value before starting the welding work. G) NEGATIVE LUG. F) POSITIVE LUG. NOTE: The terminals are designed for terminals of 1/2”. Tighten the terminal nuts that secure the connections to prevent contact failure, overheating or voltage drop.
GENERAL MAINTENANCE The fan motor has sealed bearings that not require service. Avoid dusty places, as this can block the air passages, causing it to heat the welder. Clean regularly inside the welder from dust and foreign materials using dry compressed air. The top and side panels can be removed without affecting the internal component assembly. Periodically grease with neutral grease the spindles and inner and outer brackets plunger guide. The frequency of these works will go according to the enviroment and working conditions, considering adequate at least 2 times per year. NOTE: Since the right material and the right procedures of assembly are very important, for purposes of inspection operations and replacement of coils, motor, blades, switch, rectifier as well as the general review of the machine, it is recommended to go to authorized service departments.
