Battery powered, fully automatic steel strapping machine designed for reliable, portable strapping and welding of hotmelt joints. It tightens the strap, rubs the hotmelt area, then performs the weld to complete a secure seal. Key benefits Fast, consistent sealing: automatic tightening, rubbing of hotmelt parts, and welding reduces manual work and speeds up packaging cycles. Portable and long lasting: rechargeable 3000mAh lithium battery supports extended outdoor use and frequent recharging. Flexible for different jobs: adjustable clamping force and compatible strap sizes handle a wide range of materials and applications. Durable construction: aluminum alloy, iron and plastic housing provides strength, heat resistance and corrosion resistance for long service life. Main specifications and features Strap compatibility: bandwidth 1116 mm; belt thickness 0.51.5 mm. Clamping force: adjustable from 60 to 2800 N for light to heavyduty applications. Battery: 3000 mAh lithium battery, rechargeable up to 2000 cycles. Runtime and charging: 90 minute charge delivers about 4 hours of outdoor operation; one charge can install 80 to 200 shoulder straps depending on usage. Operation feedback: LED display uses three colors to indicate working states. Blue indicates normal operation, red indicates low battery, purple indicates sealed package. Build: made from aluminum alloy, iron and plastic with advanced manufacturing for durability and stable performance. Typical applications Warehouse and distribution centers: secure pallet loads and bundle cartons for transport. Onsite construction and metalwork: strap and seal bundles of rebar, pipes or profiles where mains power is not available. Logistics and outdoor shipments: portable operation for field sealing of cargo, crates and wrapped goods. Why choose this model Delivers repeatable welds and adjustable tension to match different strap materials and load requirements. Portable battery operation removes dependence on power outlets for field work and outdoor tasks. Clear LED status makes it easy to monitor battery and sealing status during continuous use. Operational notes Verify strap width and thickness fall within the 1116 mm and 0.51.5 mm ranges before use. Adjust clamping force to suit the material and load to avoid strap or product damage. Recharge the battery after extended use to maintain consistent performance. This machine combines automatic hotmelt welding, adjustable tension control and a rechargeable power source to provide a practical solution for mobile and factory strapping needs.
