Page 6: Technical Data
3 TECHNICAL DATA The unique serial number for the machine will be printed here. Always give serial number when ordering spares or in other communication with WSS concerning your machine. Type of welding machine One-phase static transformer rectifier frequency converter, DC output. Processes MMA (Stick MIG/MAG (Metal Inert Gas/Metal Active Gas) - Page 7 X: Duty cycle Duty Cycle is percentage of 10 minutes that unit can weld at rated load without overheating. It refers to a 40°C environmental temperature. If unit overheats a thermal switch stops the output, the warning light for over-temperature is lit and the cooling fan continues to run. Wait fifteen minutes for unit to cool.

Page 8: Installation
4 INSTALLATION Only qualified personnel should perform this installation. Only personnel that have read and understood this Manual should install and operate this equipment. The machine must only be plugged into a receptacle which is grounded per applicable electrical codes. Note 1 The power switch is to be in the OFF position when installing work cable and torch and when connecting power cord to input power. - Page 9 POLARITY SELECTION In the picture below the cable supplying current to the Euro-connector is connected to the machine plus- connection. The cable to return current (ground clamp) then has to be connected to the machine minus- connection to the right in the picture. This means the machine is set for welding with electrode plus polarity from the Euro-connector to the right, which is the normal setting for MIG/MAG welding.

Page 10: Front Panel
5 FRONT PANEL 1. Wire speed adjustment. See separate table under OPERATION for relation between wire speed and approximate welding current. This adjustment is only active when one of the wire welding modes are selected 2. When this LED is lit, it means that the thermal cut-out for overheating of the machine has triggered and there is no welding current. - Page 11 7. This knob is active in the MIG/MAG mode only and allows selection between two arc types. When the led above the knob is lit a softer welding arc for MIG brazing is obtained. When the led is dark the normal, slightly crisper or harder arc is obtained. 8.

Page 26: Safety Instructions
17 SAFETY INSTRUCTIONS Arc Welding Hazards The safety information given below is only a summary of the more complete safety information found in the Safety Standards listed in Section 1-5. Read and follow all Safety Standards. Only qualified persons should install, operate, maintain, and repair this unit. During operation, keep everybody, especially children, away. - Page 27 ARC RAYS can burn eyes and skin. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching.
- Page 28 Additional precautions for installation, operation, and maintenance Do not install or place unit on, over, or near combustible surfaces. Do not install unit near flammables. Do not overload building wiring − be sure power supply system is properly sized, rated, and protected to handle this unit.
