Many Beginners Feel Intimidated When They First See a Laser Welding Machine

The label “high-tech equipment” often makes people think:
Is it complicated to operate? What if I make mistakes? Can beginners really use it?

Actually, there’s no need to worry at all!

PDKJ laser welding machines are specially optimized for beginners, featuring a simple and easy-to-understand operating logic that allows even first-time users to get started quickly.

With high welding precision, strong weld quality, and fast efficiency, laser welding is widely used in industries such as hardware manufacturing, electronics, and automotive parts.

Today, we’ve prepared a complete “PDKJ Beginner Operation Guide” for you. Just follow the steps, and you’ll be able to weld successfully with confidence!

Step 1: Preparation Before Operation | Build a Safe Foundation & Prevent Equipment Failure

Preparation before starting work is extremely important, especially for beginners.
Focus on three key areas: safety protection, equipment inspection, and parameter presetting.

1. Safety Protection

The number one rule when operating laser equipment: Safety First.

Personal Protection

• Wear laser safety goggles that match the machine’s laser wavelength

• Wear flame-retardant work clothing

• Wear heat-resistant gloves

Work Environment Protection

• Remove unnecessary objects from the working area

• Keep unauthorized personnel away from the machine

• Post safety warning signs

• Never allow the laser beam to directly contact the human body

2. Equipment Inspection

Before powering on, carefully inspect the machine to reduce the risk of malfunction:

• Ensure the machine housing is undamaged

• Check that power cables, water pipes, and fiber optic connections are secure with no looseness or leakage

• Start the cooling system and confirm that coolant levels and water circulation are normal

• Test the emergency stop button to ensure quick shutdown capability in emergencies

3. Parameter Presetting

There is no need to adjust parameters blindly.
Simply refer to the recommended settings based on the material and thickness of the workpiece.

Reference Example

For 1 mm stainless steel sheets:

• Power: 800–1000W

• Welding speed: 3–5 mm/s

Beginner Tips

• Start with lower power and slower speed

• Practice welding on scrap material first

• Fine-tune parameters according to weld quality

• Never test directly on finished products

Step 2: Welding Operation | Master the Key Techniques for Accurate Welding

Laser welding follows a fixed operating procedure.
Stay calm, follow the sequence carefully, and focus on two key areas: startup procedure and welding technique.

1. Standard Startup Procedure

1. Turn on the main power supply

2. Start the cooling system and laser generator in sequence

3. Wait 1–2 minutes for the machine self-check

4. Begin welding only after the display shows no error messages

2. Master Welding Techniques

For beginners, remember this simple rule:

“Accurate positioning, stable movement.”

Secure the Workpiece

Use clamps to firmly secure the workpiece and prevent movement or deviation during welding.

Precise Positioning

• Use the red-light positioning function to align the laser focus with the weld seam

• Keep the welding head perpendicular to the workpiece

• Maintain a distance of 2–3 mm

Maintain Steady Welding Movement

After activating the laser, move the welding head smoothly and evenly.
Beginners can use auxiliary guide rails to avoid shaking or drifting.

Observe the Weld in Real Time

If the weld seam turns black or develops pores:

• Reduce the welding speed slightly

• Or lower the power setting appropriately

Important Reminder

If abnormal conditions occur during welding, such as:

• Workpiece displacement

• Unusual machine noise

Immediately press the emergency stop button.

Always cut off the laser and power supply before handling the issue.
Never touch the workpiece or adjust parameters while the machine is running.

Step 3: Post-Welding Maintenance | Proper Care Can Extend Machine Life for Years

Many beginners simply turn off the power immediately after welding.
In fact, this can quietly damage the machine.

Proper shutdown and maintenance not only extend equipment life but also reduce future failures.

1. Correct Shutdown & Scientific Cooling

⚠️ One of the most common beginner mistakes:
Never cut off power immediately after welding!

Follow this shutdown sequence to prevent overheating damage:

• First turn off the laser emission switch

• Keep the cooling system running for 5–10 minutes to fully dissipate internal heat

• After the machine cools down to room temperature, turn off the cooling system and disconnect the main power supply

2. Cleaning, Inspection & Storage

Follow this checklist to keep your machine clean and durable:

Clean Consumable Parts

Carefully remove welding residue and dust from:

• Welding gun nozzle

• Protective lens

Avoid scratching precision components.

Organize the Workspace

Clean scraps and welding residue from the workbench to maintain a tidy operating environment.

Quality Inspection & Record Keeping

Inspect weld quality and record issues such as:

• Incomplete penetration

• Uneven weld seams

This helps optimize parameters for future work.

Dust Protection

Cover the machine with a dust cover to protect internal components.

PDKJ Tips

Regular maintenance following this process can significantly reduce equipment failure rates and make operation much easier and more reliable.

Conclusion: Beginners Only Need to Remember These 3 Key Points
