| Brand Name: | GENWELD |
| Model Number: | LW-J100 |
| MOQ: | 5 sets |
| Delivery Time: | 20 work days |
The LW-J100 is a new-generation cold welding machine developed specifically for the metal sheet industry, designed to weld metal plates ranging from 0.12 mm to 2.0 mm in thickness. Compact and highly efficient, it can be operated quickly even by users with no prior welding experience. Solder joints are silver-white, eliminating the need for post-weld polishing.

| Low Welding Temperature | The welding temperature is low enough to be touched by hand. Welded plates are not deformed or undercut. |
| Wide Welding Thickness | Plate thickness from 0.12 mm to 2.0 mm can be welded. |
| Versatile Welding Materials | Weldable profiles include stainless steel, thin iron, copper, and aluminum. |
| Smooth, Beautiful Weld Seam | The weld seam is smooth with a silvery-white fish-scale appearance — no undercut, no deformation, a minimum seam width of approximately 1 mm, and no heat-affected zone. |
| Low Operating Cost | Uses ordinary argon, with consumption at only one-fifth that of argon arc welding. |
| Labor Cost Savings | Anyone with or without welding experience can get started quickly. Operation is simple and convenient — no professional welder required. |
| Deep Welding Penetration | Post-weld penetration depth is several times greater than that of laser welding and reaches or exceeds the penetration depth of argon welding. |
| Convenient CPU Chip Control | Utilizes German-original CPU control for more convenient welding temperature adjustment. For example, a 1 mm plate can be welded on one side and formed on both sides, or the front side can be welded with no color penetration on the back. |
