WOW - that's pretty cool video - easy, too.

"Handheld laser welder speed is 4-10 times faster than the traditional TIG/MIG welding
Easy to operate, unskilled operator can also weld products beautifully
Can weld metal products of different materials and thicknesses
Low welding heat, no deformation of the workplace
Smooth and beautiful, which reduces the subsequent grinding process and saves time and cost by laser welder"
