KOZA-KZH-JH605-1500 Welding Robot (5 kg)
KOZA-KZH-JH605-1500 is a new-generation KOZA KZH-JH six-axis industrial welding robot with a 5 kg payload, 1494 mm reach and ±0.05 mm repeatability. Hollow routing keeps torch cables inside the arm for freer welding motion. It can be supplied as a package with a 350 A robot-dedicated intelligent welder and an air-cooled anti-collision torch. Typical uses include arc welding of hardware and sheet metal. KOZA is a Hong Kong-funded enterprise with factories in Guangzhou and Foshan.
Key selling points
- Fast and precise: ±0.05 mm repeatability; wrist J6 up to about 927°/s.
- 1494 mm reach: covers typical welding stations; floor, ceiling or wall mounting.
- Hollow routing: torch cables inside the arm for less interference.
- Complete welding package: 350 A robot welder + air-cooled anti-collision torch + cabinet + touch pendant.
- Easy robot power: single-phase AC220V / about 3.6 kW; welder side uses 3-phase AC380V.
- Processes: carbon steel / stainless arc welding, with optional simple TIG, MMA, gouging and fast-weld modes (depending on welder).
