1. GENERAL DESCRIPTION UWW-161 TP is a compact and portable Single Phase Inverter Power Source for professional MIG-MAG, TIG and MMA welding. It connects to a standard 230V one phase socket, preferably with slow fuses to allow full power. The TP (total protection) version is protected against too high input voltage and will close down completely to prevent damage if input voltage exceeds 285V. A led on the rear panel will be lit to indicate that the protection is on.
2 IDENTIFY COMPONENTS UWW-161 TP complete, product number 193-161161 is delivered with 1 Primary cable, 2.5m with plug (fitted on machine) Gas hose socket with nut and hose clamp 1 piece 2 Product number 161165 1 set Drive roll V groove, 0.6-0.
3 TECHNICAL DATA TP 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.
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. Reduce amperage or duty cycle before starting to weld. I2= Welding current.
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. Note 2 The parts behind the wire drive door are live when wire welding.
POLARITY SELECTION In the picture below the cable supplying current to the Euro-connector is connected to the machine plusconnection. The cable to return current (ground clamp) then has to be connected to the machine minusconnection 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.
5 FRONT PANEL 1 2 6 7 4 3 5 8 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. Do not switch the machine off.
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. Mode selection 2 step wire welding • Bring the torch close to the piece you mean to weld. • Press (step 1) and hold the torch button. • The wire advances at closing speed until it contacts with the work-piece.
6 SPOOL COMPARTMENT Gas post-flows pot-meter the gas post-flow for MIG and TIG can be adjusted from 0-3 seconds. It must be long enough to ensure sufficient cooling of the weld pool to avoid oxidation. Fuse for the auxiliary transformer providing current to the wire feed motor: 800mA 250V slow fuse. Wire feed system with drive rolls and pressure adjustment. Shaft for spool attachment and Friction Brake Adjustment The drive rolls have two grooves for two different wire sizes Revision date: 26.02.
7 WIRE LOADING Release the spring loaded pressure arm (1) rotate the roll arm (2) up from the wire feed drive roll (3). 1 Ensure that the groove size in the feeding position on the drive roll matches the wire type and size. 2 Place the wire spool in place on the wire spool spindle (4). Make sure that the stud (5) engages in the corresponding hole in the wire spool 8 Check the Friction Brake Adjustment, a bolt inside the spindle (6).
8 OPERATING INSTRUCTIONS Contact Tip Nozzle Torch Neck 1. Welding wire has been selected 2. Correct polarity to the torch / welding wire has been selected 3. Wire spool has been inserted, spool brake has been checked, wire inserted in the central connector, and the idle roll arm has been closed. 4. Torch has been connected to the front of the machine 5. Return clamp has been properly connected to the work piece 6.

14 TROUBLESHOOTING PROBLEM The machine does not start. CAUSE − No current to the machine. − Voltage reaches the machine switch but there is no voltage after the contacts. − There is voltage after the switch but the machine does not start SOLUTION • Make sure that power is available at the socket you plug in to and that the power supply cable is intact.
PROBLEM No output voltage Primary fuses blow The welding is not optimal. The machine stops welding and emits an acoustic signal (sound alarm). Non optimal wire welding start. No gas from the solenoid valve The torch button does not work The machine always welds at maximum current. CAUSE Check for a short circuit at the DINSE plug with a diode tester.
PROBLEM CAUSE The wire feeding unit motor does not work. − Primary fuse of the auxiliary transformer is damaged − Control signals from the front panel do not reach the motor board. − The motor board is damaged. SOLUTION Unplug the machine. The delayed fuse 5x20 800 mA on the back of the machine must be replaced. • Check the connection of the motor feeding wire on the front panel and after that check the continuity between the front panel and the amphenol connector (picture 9).
PICTURE 3 PICTURE 4 To check the inverter, carry out the following measurements with a diode tester: Should there be a short-circuit on one of these measurements or an “OL” instead of a numeric value, the power board must be replaced. PICTURE 5 The varistor is a blue disc near the ground wire of the power board. This device is necessary to protect the board from input overvoltage. When there is overvoltage it “explodes” , normally causing a short circuit.
PICTURE 6 To check the mosfet of the switching power supply unit, carry out the following measurements: Should there be a short-circuit on one of these measurements or an “OL” instead of a numeric value, the power board must be replaced.

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. ELECTRIC SHOCK can kill. Touching live electrical parts can cause fatal shocks or severe burns.
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. Wear approved safety glasses with side shields under your helmet. Use protective screens or barriers to protect others from flash and glare; warn others not to watch the arc.
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. FALLING UNIT can cause injury. Use lifting eye to lift unit only, NOT running gear, gas cylinders, or any other accessories. Use equipment of adequate capacity to lift and support unit.
