Overview

The HEROLASER eH20L-MM01 is a 2000W air-cooled handheld laser welding system with automatic wire feeding. The air-cooled design eliminates the external chiller required by comparable water-cooled machines, cutting both the footprint and the energy draw.

At 2000W it sits at the upper end of handheld laser welding, with the power to handle thicker material and faster travel speeds than lower-wattage systems. A 14 μm energy transmission fiber delivers a tightly controlled beam, producing welds without marking or discoloration on the surrounding surface.

Key Features

2000W laser power for thicker material and faster welding
Air-cooled system, no external chiller required
Reduced energy consumption compared to water-cooled systems
14 μm energy transmission fiber for high weld quality
Welds without surface marking or discoloration
Multi-angle nozzles for precise welding on varied joint geometry
Automatic wire feeding
Safety circuit protects against accidental leakage
3 meter fiber length for working reach
Compact, portable handheld format

Applications

Ideal for:

Production fabrication and metalwork
Stainless steel welding including railings, cabinets, and enclosures
Thicker material where lower-wattage systems reach their limit
Work where finish appearance matters and discoloration is unacceptable
Industrial maintenance and repair
Shops without space for a chiller installation

Performance & Functionality

Power is the practical difference at 2000W. Higher laser power means faster travel speed on the same material and the ability to weld thicker sections than 700W or 1000W systems can handle. For a shop running production volume rather than occasional work, that translates directly into throughput.

The 14 μm energy transmission fiber concentrates the beam tightly, which is what produces a weld without heat spreading into the surrounding surface. On stainless in particular this means no discoloration to clean up and no marking around the joint, so parts move to finishing rather than to a grinder.

Multi-angle nozzles let the head reach joints that a fixed-angle nozzle cannot approach cleanly, which matters on corners, internal angles, and assemblies with limited access.

Air cooling removes the chiller entirely. No coolant maintenance, no plumbing, no fixed footprint, and lower energy consumption than an equivalent water-cooled setup.

Why Choose the eH20L-MM01?

Handheld laser welding at 2000W is normally water cooled, which means a chiller, coolant maintenance, and a permanent spot on the shop floor. The eH20L-MM01 delivers that power level without any of it.

For a shop that has outgrown lower-wattage systems and needs to weld thicker material or move faster through production volume, this is the step up. The 14 μm fiber and multi-angle nozzles mean the increase in power does not come at the cost of weld appearance or joint access.
