SV-LW Series
The SV-LW Series replaces the traditional fixed optical path with a handheld welding gun, so the operator can weld at distance and reach joints a fixed worktable cannot accommodate. Red light positioning, spot adjustment from 0.1 to 5mm and a 1–10000Hz frequency range produce deep, firm welds with little deformation — solving the burn-through, weld nodule and finishing problems typical of argon arc welding.
Key Features of the SV-LW Series
Handheld welding gun replaces fixed optics
more flexible and convenient, enabling long-distance laser welding and overcoming the travel-space limitation of a worktable.
Red light positioning
used for welding head correction so the welding position is more accurate.
Large welding depth with firm welds
strong, reliable joints.
Low deformation and easy to polish
solves the burn-through, weld nodule and weld quality problems caused by argon arc welding.
Wide process window
laser frequency 1–10000Hz and spot adjustment 0.1–5mm, suitable for complex welds and spot welding.
Built-in dual-temperature water cooling
Hanli cooling system integrated within the cabinet.
Choice of core components
MAX, Raycus or BWT laser source; SUP, Raytools or Relfar welding head with wire feeding system.
