SM-WC-LR Li’l Runner (HS) 23. Keep the torch cables away from the surface. Hang them to decrease the load applied on the carriage. Use only cables whose weight is not more than 8 kg (18 lbs) for horizontal work and 6 kg (13 lbs) for vertical work. 24.
SM-WC-LR Li’l Runner (HS) 3. STARTUP AND OPERATION 3.1. Preparing Use the carrying handle to transport the carriage to the worksite. Then, set to ‘O’ all switches (power, travel direction, and arc ignition switch) and the magnet lever. Next, connect the carriage to the power source, and then put the torch into the torch holder and tighten with the screws.
SM-WC-LR Li’l Runner (HS) 3.2. Connecting to the welding circuits The carriage can control two torches by using the arc ignition cable plugged into the arc ignition socket. To do this, refer to the diagram from Fig. 2 and connect one blue- jacketed wire to one terminal of the welding circuit.
SM-WC-LR Li’l Runner (HS) 3.3. Positioning at the worksite Put the guide arms so that the carriage is in constant contact with the workpiece. You can set them by a constant step (interval adjustment), or continuously after you swap them (continuous adjustment). To set them correctly when the carriage moves to the left, use the 4 mm hex wrench to loosen the screw that secures the right guide arm.
SM-WC-LR Li’l Runner (HS) To put the carriage closer to the workpiece, use the 4 mm hex wrench to remove the roller assemblies. Next, install them at the other end of the guide arms, and then swap the guide arms (Fig. 3). Switch the magnet ON/OFF lever from left (‘O’) to right (‘I’).
SM-WC-LR Li’l Runner (HS) 3.5. Changing the unit of speed To change the unit of speed between centimeters per minute and inches per minute, unplug the carriage from the power source and follow the steps shown in Fig. 4. Use the 2.5 mm hex wrench (not included) to loosen the screws and get access to the back side of the control panel.
SM-WC-LR Li’l Runner (HS) 3.6. Troubleshooting Message Problem Solution Display not fully on after powering. Contact service center for check and repair. Refer to the section “Changing the Speed shown in centimeters per unit of speed.” minute instead of inches per minute.
