110V 3HP Portable Line Boring and Welding Machine, 2 in 1 Professional Line Bore and Welder Kits, European Connector, Boring Range 2.16"-11.8", Welding Range 1.96"-11.8"

Attentions: This portable line boring and welding kits doesn't include MIG welder. The choice of welding machine can be used normally as long as the interface is a European style joint and the joint matches.Specifications：Control mode: manual/automaticApplication: Boring, repair welding inner holeMain motor power: 2.35KW/3HPFeed motor: torque 40Nm (gear transmission) torque 8.5Nm (worm gear)Voltage: AC110V 50/60HZWorking stroke: 260mmMain engine speed: 0-390r/minBoring diameter: 2.16"-11.8"/55-300mmFeeding speed: stepless speed regulationThe maximum amount of knife cutting on one side: 3mmRepair welding diameter: 1.96"-11.8"/50-300mmMachining roughness: Ra3.2Machining hole roundness: ≤0.02mmPackage Contents: ENT-0227331 x 2in1 Portable Line Boring and Welding Machine1 x Necessary Attachments1 x User Manual

• Portable Design: Features a compact and modular setup with bolt and weld mounting for easy disassembly, transport, and on-site use—ideal for field repairs of excavators, loaders, and other heavy machinery requiring concentric or parallel hole alignment.
• Powerful 110V 3HP Motor: Delivers high torque at low speed for smooth, vibration-free boring and welding operations; includes stepless speed control for both spindle and feed to match varying job requirements with consistent precision.
• Precision Boring Bar: Constructed from heat-treated alloy steel for enhanced hardness, wear resistance, and fatigue strength; allows tool holder positioning at any point within the 2.16"–11.8" boring range while maintaining accuracy.
• Integrated Safety Function: Equipped with a red emergency stop switch that immediately cuts power in both boring and welding modes, ensuring rapid shutdown to protect operators during unexpected situations.
• 2-in-1 Line Bore and Welder Capability: Combines line boring and welding in one unit to efficiently restore shaft pin holes, hinge joints, and rotary bores on construction equipment; supports end-face boring for versatile post-weld machining tasks.
