200 W Nd:YAG laser pumped by a pulsed xenon lamp, 1064 nm
Up to 100 J per pulse; 0.2–15 ms pulse width; 1–20 Hz
0.1–2 mm spot for fine joints on jewelry, frames and dental work
Maxwave LS-W200 pulse power supply, made in-house
Compact 850 × 500 × 360 mm cabinet with integrated chiller

Overview

This welder uses a lamp-pumped Nd:YAG laser to fuse small metal parts with short, high-energy pulses. You aim through a 10× microscope and fire single pulses or a fast series at up to 20 Hz. The beam focuses to a spot between 0.1 and 2 mm, so each weld is small and neat and the heat stays close to the joint.

It suits benches that handle several kinds of fine work: gold and silver jewelry, eyeglass frames, dental frameworks and small mould details. Most joints need no solder, and the finished welds need little cleanup.

Configuration

Laser: Ø7 mm Nd:YAG crystal in a ceramic reflector cavity, pumped by a pulsed xenon lamp. 1064 nm, 200 W.
Pulse: up to 100 J, 0.2–15 ms, 1–20 Hz.
Power supply: Maxwave LS-W200 pulse power supply.
Cooling: chiller integrated in the cabinet, with over-temperature alarm and flow protection.
Control: single-chip (PIC) controller with simple parameter settings.
Viewing: 10× microscope.
Size: 850 × 500 × 360 mm; maximum input power 7 kW.

Typical applications

Repairing and assembling gold and silver jewelry
Eyeglass frames
Dental frameworks
Small repairs on moulds
Joining parts in bronze, aluminium, steel and titanium

Options and customization

The machine is built around 200 W average power. For a larger cabinet with the same LS-W200 power supply, see our 100 / 200 W desktop jewelry welder. We can configure the mains voltage and plug for your country. Every machine carries our 2-year whole-machine warranty, and operator training at our Wuhan factory is free.

FAQ

About this machine

What does portable mean for this welder?

It is a compact desktop unit, 850 × 500 × 360 mm, with the chiller built in, so it fits on a standard bench and can be moved between rooms. It runs on mains power, and its maximum input is 7 kW, so check your circuit before installation.

Which metals can it weld?

Gold, silver, bronze, aluminium, steel and titanium. That covers most jewelry, eyeglass-frame and dental alloys.

How hard is it to learn?

The control system is simple, and most operators pick up the basics in a short session. We also offer free training at our Wuhan factory.

Who makes the laser power supply?

We do. Maxwave started in 2009 by building laser power supplies, and this welder uses our own LS-W200 pulse supply, so the power supply and the machine are serviced by the same team.
