For connection issues with the Au3Tech HW980, follow these troubleshooting steps:

1. Touch Screen and Controller (Alarm Err-E001):
- Check that the touch screen is properly connected to Controller 1.
- Ensure Controller 1 is powered on and has started correctly.

2. Welding Head Communication (Alarm Err-W001):
- Verify the connection between the welding head and the controller is correct.
- Check if the welding head screen displays an image.

3. Wire Feeder Communication (Alarm Err-S001 – optional):
- Inspect the communication line between the controller and the stepping wire feeder.
- Power off the device, reconnect the communication interface, then power on.

4. Stepping Wire Feeder Driver (Alert Err-S002 – optional):
- Check wiring between the motor and the driver.
- Confirm the power supply voltage is 24V.

5. Stepping Wire Motor Interface (Alarm Err-S003 – optional):
- After powering off, check the connection between the motor and the interface.

These steps help resolve communication and connection errors in the system.

Page 11: Mechanical Installation
Mechanical installation Waterway installation The HW980 handheld welding head is equipped with a set of cooling water channels. It should be noted that when the laser power is greater than 500 watts, it is recommended to use water cooling. The location and number of water-cooling interfaces can be seen in Figure 3, and the table below details the recommended water flow rates.
Page 12 Industrial pressure gauges will suck in air, and if a rubber diaphragm is used, hydrocarbons will be produced due to aging and other reasons. HW980 provides 1 way welding gas connection. The outer diameter of the gas pipe is 6mm. As shown in Figure 4 below.
Page 13: Optical Fiber Interface
HW980 is suitable for most industrial laser generators. It is equipped with a collimator lens assembly. The connection between the end of the optical fiber and the welding head is called the optical fiber connector. HW980 comes standard with QBH optical fiber connector, as shown in Figure 5 below.
Page 14 Figure 5 HW980 optical fiber input interface - QBH Note: The optics must be kept clean, and all dust must be removed before use. If the welding head is to insert the optical fiber vertically, the welding head must be rotated 90 degrees to a horizontal position, and then insert the optical fiber to prevent dust from entering the interface and falling on the surface of the lens.
Page 15: Beam Focusing
Figure 6 HW980 QBH fiber optic connector insertion and locking diagram Beam focusing Adjust the focus position The welding head can adjust the focus position. The adjustment method is to rotate the locking ring counterclockwise. After loosening, adjust the length of the copper nozzle to obtain the required spot energy.
Page 16: Cleaning And Maintenance
Spot centering adjustment Adjust the light spot to the horizontal center position of the nozzle. Adjustment method: power on the HWS980 galvanometer handheld welding system and then set the "Width" to 0mm on touch screen → click "advanced parameters" → enter the password "2000" → click "ENTER" → set the "optical core offset" parameter.
