The control knob is arrowed in Fig 1. Electrode pressure may be mechanically adjusted from 40 to 120kg, to spot weld low carbon sheet steel up to 1 + 1 mm in thickness. MODEL CSW13T The most important features of this 230V 50Hz Portable Spot Welder are controlled by a microprocessor, managed from the control panel shown in Fig. 2. These features are: 1. Welding time, set according to the thickness of metal to be welded. 2. Changing selection for welding thickness. 3. Changing resistance welding machine operating mode... normal or pulse. Selecting ‘PULSE’ mode improves welding capacity on material with high yield points or materials with protective coatings. The pulsation period is preset and does nor require adjustment. 4. Electrode pressure may be mechanically adjusted from 40 to 120kg, to spot weld low carbon sheet steel up to 2 + 2 mm in thickness. BOTH MODELS Both 120mm electrode arms and standard electrodes are provided. An eye bolt may be fitted to the machine (see your Clarke dealer), for use in supporting the machines weight when repetitive welds are required (see your Clarke dealer. IMPORTANT!

Please report any damage which may have occurred during transit, to your CLARKE dealer immediately. No Description No Description A 1 x Handle D 2 X Hex Wrenches B 2 x Electrode Holders F 1 x M6 Bolt C 2 x Electrodes (straight)
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com PREPARATION FOR USE 1. Fit the electrodes to the electrode arms. Whether or not the longer electrode is located in the upper or lower arm, depends upon the work in hand. It may be necessary for example to reach over a lip in a workpiece, necessitating the longer electrode to be positioned in one particular arm. Normally however, the longer electrode is located in the upper arm. Nip up the clamps but do not fully tighten. 2. Depress the operating lever fully and insert the M6 bolt provided, into the threaded hole as shown in Fig 5. 3. Screw in fully so that the lever is held in the fully down position as shown. This is the position used for adjusting the electrode gap. 4. Before setting the electrode gap however, it is important to ensure that the electrode arms are parallel to each other and the electrodes are perfectly in line, on the same axis, when the operating lever is fully depressed. This is achieved by slackening the respective arm clamp and rotating the arms within the receptacle until the electrodes meet exactly and are perfectly in line. When satisfied, tighten the clamps. 5. Slacken off the upper electrode clamp and move the electrode so that a piece of material of the same total thickness as that to be welded, can be inserted between the electrodes, then tighten the electrode clamp. The correct gap is now set. 6. Remove the M6 bolt and release the lever. 7. Adjust the pressure to be exerted by the electrodes by turning the adjuster screw (item 1, Fig.3), using the hex. wrench provided, (clockwise to increase, anticlockwise to decrease) according to the scale shown in Fig 6. WARNING: ENSURE THE WELDER IS DISCONNECTED FROM THE POWER SUPPLY BEFORE PROCEEDING
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com NOTE: Always remember that too high a pressure will result in damage to the electrode tips, whereas too little pressure will result in a poor weld. Pressure is also dependant upon the length of electrode must be taken into account if/when replacing the electrode arms with any of those available from you Clarke dealer, (see Accessories). 8. Set the welding time by either turnin g the dial adjuster, shown in Fig 1, (model 6T), or pressing the button shown at 1 Fig 2 (model 13T). Generally the thicker the workpiece, the longer the welding time. NOTE: The time scale shown on the control panel of the 13T is a general guide only. It is advisable to make a few test welds on material similar to the workpiece before commencing work, making adjustments of pressure and welding time, as necessary, until a perfect weld is achieved. MODEL 13T only button on the control panel accordingly. (Button 3, Fig 2) 2. Select the welding thickness by pressing the appropriate button on the control panel accordingly. (Button 2, Fig 2) OPERATION IMPORTANT: 1. Ensure the work surfaces are perfectly clean. There should be no rust or other contaminants which would seriously impair the quality of the weld. Ideally, the workpieces should be clamped together. IMPORTANT: 2. Ensure the electrode tips are correctly formed. They should be checked regularly when welding to ensure they make perfect contact with the work. A Spot Welding Tip dresser is available from your Clarke dealer. With the machine correctly adjusted, connect to the mains supply. WARNING: BE AWARE THAT THE MACHINE PRODUCES VERY INTENSE ELECTROMAGNETIC FIELDS. THIS COULD SERIOUSLY EFFECT PEOPLE WEARING PACEMAKERS OR FITTED WITH PROSTHESES. THESE PEOPLE SHOULD NOT BE ALLOWED TO USE THE MACHINE OR BE IN ITS VICINITY. MALFUNCTIONS OR DAMAGE TO WATCHES, MAGNETIC CARDS, INSTRUMENTATION, DATA TRANSMISSIONS OR TELEPHONE RECEPTION COULD ALSO OCCUR. THESE POINTS MUST ALWAYS BE TAKEN INTO CONSIDERATION WHEN SITING THE WELDER
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com Bring the lower electrode up to th e work so that it is positioned directly beneath the point to be welded. Depress the operating lever fully so that the microswitch is activated, and hold in this position for a short period. Current to the electrodes will automatically shut off after the welding time has been reached, at which time you may withdraw the welder. A short delay, from the end of the weld cycle to removing the electrodes, will improve the weld characteristics. Should the welder not operate correctly or a particularly poor weld is produced, the following checks may determine the cause. 1. Ensure the work is perfectly clean. 2. Ensure the welding parameters are all correct. 3. Ensure the microswitch is actually pressed and held for the duration of the weld. 4. Ensure the thermal overload has not been activated. NOTE: The thermal overload is a protection device which operates when the electrical circuits have overheated. This prevents the machine from operating until it has cooled down to satisfactory levels. The device will operate if the DUTY cycle has been exceeded or if the ambient temperature becomes too high. NEVER EXCEED THE DUTY CYCLE - See Specifications. NOTE: On model 13T, if the thermal overload has intervened, the two lamps shown in Fig 7 will flash alternately.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com MAINTENANCE Frequency of maintenance operations depends on the operating conditions: how intensively the welder is used, how clean or dirty the welding site is (aggressive atmospheres, etc). Before use, always inspect the welder, checking for security and cleanliness of arms and electrodes to ensure they are in perfect condition. Ensure also that the power cable is in perfect condition at all times. As a general rule the power supply should be inspected internally at least twice a year. 1. Access the inside of the machine by removing the screws securing the side cover and carefully hinge the cover down. 2. Clean the transformer using a blast of dry compressed air with a maximum pressure of 10 bar. NEVER direct the compressed air jet on to the circuit boards. These should be cleaned with a soft brush and vacuumed or blown with air at very low pressure. ALWA YS use a face mask for these operations. 3. Check all wiring for insulation damage or loose or oxidised connections. Repair/replace where necessary. Check all screws and connections are tight and there are no signs of oxidation or overheating. 4. Replace the cover. WARNING: ELECTRICITY CAN KILL. NEVER TOUCH LIVE ELECTRICAL COMPONENTS. DISCONNECT THE POWER SUPPLY BEFORE ALL INSPECTIONS AND MAINTENANCE OPERATIONS. BEWARE HOT ACCESSING INTERNAL COMPONENTS. WARNING: NEVER CONNECT THE MACHINE UNLESS THE COVER IS REPLACED.
