Overview
This manual describes the safe use, basic installation, factory settings, operation
instructions, and maintenance services of the HW9XX (handheld welding) series
4
products. There are many specific optical and mechanical custom configurations, and
this manual only introduces its main unit components.
Laser welding is a new welding method and handheld laser welding is more widely in
used. The handheld laser welding head has the advantages of beautiful appearance,
small and light weight, wide use range, simple operation, and fine weld seam, which
greatly improves the welding efficiency and quality. Hand-held laser welding solves the
existing welding problems such as poor welding of corners, insufficient welding, post-
processing of welds, unsightly welds and so on, which makes it the first choice for most
metal welding.
Safety Instructions
Please read the following safety precautions and suggestions carefully before operating
the laser and handheld laser welding head.
1. Please observe all safety instructions for laser (including but not limited to
descriptions of laser and the related chapters in this document)
2. Please ensure that do not look directly at the laser beam at any time or under any
circumstances. Do not look at the laser emitter port directly even if wearing laser
protective goggles.
3. It is forbidden to aim the laser at any human body, animal, vehicle, sky, etc. The
operator shall be legally liable for the (direct, indirect and incidental) injury to the
object, and the company shall not bear any liability and loss.
4. When using laser, wear laser protective goggles of the corresponding wavelength
to protect your eyes from the threat of laser.
5. At any time, please turn on the power of the controller and other control parts
before turning on the power of the laser. Otherwise, it may cause injury by
uncontrollable laser beam.

6. Any repair or maintenance must be done by professionally trained personnel!
Professionals must have received safety training, understand possible hazards
and be familiar with safety measures to deal with hazards.

As shown in Figure 2, the welding head consists of seven basic units: QBH
connector, collimator lens unit, galvo-lens unit, wireless control unit, focus lens unit,
protection glass unit and nozzle unit.
Figure 2 - Structure of HW970
⚫QBH connector: complete the access and lock of the optical fiber connector.
⚫Collimator unit: complete the fiber collimation function and collimate the
incident laser into a parallel beam.
⚫Galvo-lens unit: Vibrate and reflect the collimated parallel laser at a certain
angle to change the direction of the original beam and the shape of the spot.

⚫Wireless control unit: quickly adjust some high-frequency parameters.
⚫Focus lens unit: Focus the reflected beam into a convergent beam with high
power density.
⚫Protection glass unit: The protective glass can protect the focusing lens from
the damage of returning slag and prolong the service life of the focus lens.
⚫Nozzle unit: guide the focused beam to the workpiece, and generate high-
speed airflow to protect the molten pool from oxidation to achieve high-quality
welding results. You can also adjust the focus distance by adjusting the nozzle
length.
Product Highlights
⚫Cool appearance, ergonomic design, comfortable to grip
⚫Adjustable spot size, high welding firmness, beautiful lines
⚫Wireless control module, quick adjustment of parameters, one button to
complete wire feeding or rewinding
⚫The light spot can be adjusted to the center position
⚫Selection of high-quality precision optical components, excellent and stable
beam quality
⚫Compact structure design, high dustproof level

Operation steps
10
1.Connect the circuit between the laser, the controller and the galvanometer driver.
Connect the power cord. For the wiring method, refer to the electrical control section of
the user manual.
2. After getting the laser welding head, connect the optical fiber connector firstly, and
then connect the air pipe, water pipe and switch circuit. (Thedetailed installation
method of each connector is described later)
3. Turn on the power of the controller and wait for the screen of the laser controller to
start up, then turn on the laser switch and the water cooler switch.
4. Set the relevant values on the controller screen (refer to the <User Manual Electric
Control Part> to set various parameters)
5. Put on goggles, hold the welding head with the welding head facing the metal welding
piece, and observe whether there is red light at the copper nozzle of the welding head.
If there is no red light, check whether the laser emits light normally.
* Note: Observe the red light from the side of the welding head, and it is strictly
forbidden to look directly at the laser beam with your eyes.
6. Position the welding parts, adjust the angle of the welding head to make the red light
shine on the seam to be welded, and the copper nozzle touches the welding parts, and
then manually turn the switch on the welding head to start light welding.
*Note: if only part of the red light comes out of the nozzle or the red light cannot be seen
at all, do not emit the laser.
