3 in 1 A70i Portable Handheld Air Cooled 700W Laser Welding Machine For Metal

An air-cooled laser welding machine is a welding system that utilizes air as the cooling medium to dissipate heat generated during the laser welding process. Unlike water-cooled systems that rely on liquid coolant, air-cooled machines use fans or other air circulation methods to maintain optimal operating temperatures for the laser components. This design simplifies maintenance and reduces the need for elaborate cooling systems, making it a more compact and versatile solution for various welding applications.

LightWELD - Turnkey Handheld Laser Welding & Cleaning Systems
● Adjustable laser welding power up to 1500 W
Preset & user-defined modes optimize material-thickness combinations
Wobble welding controls for 5 mm of additional weld width
Rear panel provides intuitive connections for power, process gas and external accessory controls
Cleaning power up to 2500 W peak for greater welding quality and finishing capability
Less Heat & Distortion for More Productivity & Flexibility
TIG welding is a time-consuming, two-handed welding method that requires an experienced, highly-skilled operator. TIG welding may
generate extreme heat that deforms thin materials, produces poor visual finishes, is difficult when welding copper, and limited when welding metals of dissimilar thicknesses.
MIG welding requires consumable wire, material pre-cleaning and beveled joints for thick metals for full penetration. Travel and work angles are limited and vertical positions are extremely challenging.
LightWELD enables dramatically faster welding, is easier to learn and operate, and provides higher-quality, consistent results across a wider range of materials and thicknesses than MIG or TIG with minimal
distortion, deformation, undercut or burn-through.
Factory Presets Ensure Optimized Welds & Cleaning
●Simple preset selection ensures consistent high-quality laser welds and cleaning
●Presets include wobble welding function to accommodate wider seams and for parts with poor fit-up
●Operators can instantly switch between presets to process multiple material-thickness combinations
●Advanced operators can customize presets, save for future use and can be used by novice operators to produce the same results
LightWELD is Fast & Easy to Set Up
Ergonomic, compact and proven to be the most comfortable and easy to use laser gun with built-in wobble welding functionality.
2-step trigger and part contact sensor enhance operator safety
Purpose-built nozzle tips for various weld joint types and pre and post weld cleaning applications
A single cable from the unit delivers laser power, gas and control connections to the gun
Fast and Easy Setup
Clearly labeled rear connections make getting started fast and easy
Simply plug in power cord and gas connection, attach clamp to work surface, and the system is ready to go.
Laser power, gas, and gun control are delivered through a single cable.
An ethernet computer connection provides access to advanced parameter settings to fine tune and save process parameters.
Optional Wire Feeding Package
Wire welding capability extends laser welding applications to poorly fit-up parts
Used for low carbon steel, stainless steel, aluminum and non-ferrous metals and alloys
Wire feed speed range 40 – 600 cm/min (15 - 230 ipm)
Wire diameter capacity 0.8 to 1.6 mm ( 0.035''- 0.063'')
Wire feed tips: 0.8mm, 0.9mm, 1.2mm, 1.6mm
Handheld Laser Welding & Cleaning Systems
Easy to Learn
Built-in factory presets for welding and cleaning reduce learning curves, new welders can be trained within hour and experienced welders realize an immediate increase to productivity
Highly Productive
High-speed welding that is 4X faster than TIG, with simple material preparation and minimal post-finishing, plus wobble welding and wire feed options for consistent high-quality results
Highly Capable
Easily weld and clean thick, thin and reflective metals with low heat input from < .040" (1.0mm) up to 1/4" (6.35mm) with minimal part distortion, improved visual appearance and increased overall part quality
