**HY-350N Welding Machine Instructions** **1. Front Panel Components (See Table 1 for Details)**

Table 1

**Wiring:** Connect the 12-pin aviation plug female of the welder to the 12-pin aviation plug male of the control cabinet. Ensure that the positive and negative wires are connected to the 13th positive and 12th negative terminals, as shown in the diagram above. The 6-core aviation plug male from the welder should be connected to the corresponding female connector on the robot. **Gas Inspection:** Set the ship-type switch 10 to position "1" for gas inspection. If the welding gun head is properly supplied with gas, it indicates that the system is functioning correctly. **Welding Settings:** - Set ship-type switch 3 to "0" for solid core wire. - Set ship-type switch 4 to "0" for 1.0mm welding wire. - Set ship-type switch 8 to "1" for gas shielded welding mode. - Set ship-type switch 9 to "1" for arc welding. - Set ship-type switch 10 to "0" for arc welding and also for welding file settings. **2. Rear Panel Components** **Wiring:** - Connect the 380V power line. - Locate the start switch. - Ensure the COâ‚‚ heater is properly connected. **Control Cabinet Manual** **1. Power On and Off Procedures (Figure 1)**

**1.1 Power On Procedure:** The panel switch serves as the main power switch for the control cabinet. Turn it to “ON” to activate the “CRP power” indicator light, which powers the CRP controller. Rotate the rear key switch to “ON,” then press the “Start Power” button. You should hear the AC contactor engage, and the power indicator lights up, confirming that the electrical cabinet is fully powered. **1.2 Power Off Procedure:** When the electrical cabinet is fully powered, turn the key switch to “OFF.” You will hear the AC contactor disengage, and the power indicator turns off. Then, rotate the panel switch to “OFF” to completely power down the system. The panel switch is the main power source for the electrical cabinet. **1.3 Emergency Stop Button Usage:** The emergency stop button should only be used in an emergency or when the robot poses a threat to personnel. Pressing this button immediately cuts power to the system and stops the robot. It must not be used in non-emergency situations, as it may cause damage to the structure or servo motors. **2. Transformer Wiring Instructions:** Connect the transformer’s input to a three-phase 380V (+10/-10) power supply. Ensure that the power is not out of phase and that all three phases are balanced. An unbalanced or out-of-phase supply can lead to unpredictable behavior from the robot. Always check before connecting.

**CRP Teach Pendant Quick Guide** **1. Button Description:** This guide provides a visual reference of the teach pendant buttons, helping you understand their functions more clearly. This makes it easier to remember and operate the system effectively.

**2. Mode Selection:** Use the mode selection buttons to switch between different operational modes such as manual, automatic, or programming.

**3. Safety Switch Instructions:** The safety switch is used to protect the operator during maintenance or emergencies. Always ensure it is in the correct position before operating the robot.

**4. Manual Joint and Coordinate Control:** Learn how to manually move each joint of the robot using the coordinate system. This allows precise control during setup and teaching.

**5. Manual Teaching and Running the Robot:** Follow the steps to manually teach the robot its path. Use the teach pendant to move the robot and record the positions.

**6. Teaching Programming Steps:** Use the teach pendant to create a program by recording motion paths and welding parameters. This step-by-step guide helps you build a complete welding program.

**7. Program Execution:** (1) Dial the key switch to the "Play" mode, set the machine speed to 5% for slow operation, and ensure the emergency stop button is accessible. Check if the arm moves according to the programmed path. If not, stop immediately. (2) If the movement is correct, gradually increase the speed to the desired level for full operation. This comprehensive guide ensures safe and efficient use of the HY-350N welding machine and related systems. Always refer to the official manual for detailed specifications and safety guidelines.
