Portable Bore Welding Machine
Portable & Lightweight Design: Compact size (50kg) with easy transportability, ideal for on-site construction and repairs without space restrictions.
Versatile Welding Capabilities: Supports boring, fixed-length boring, spiral welding, and swing welding for diverse applications (Φ40–250mm range).
Precision Digital Control: Digital system ensures accurate operations with 0.1–200r/min spindle speed and timed automation for unattended tasks.
Broad Compatibility: Works with any gas-shielded welder interface, adaptable to industrial and mining repair needs (e.g., pin holes, bearing holes).
Robust & Safe Performance: 2.3KW power with strict safety protocols (grounding, arc protection, ventilation) and durability for harsh environments (-10°C to +40°C).
The portable butt welding machine developed by our company is specially designed for on-site construction. It is small in size, light in weight, good in boring and welding. It is not required for use environment and space, and is easy to carry. It is widely used in the repair of round holes such as pin holes and bearing holes of large-scale equipment and engineering machinery. It is an indispensable tool for industrial and mining enterprises and on-site maintenance.
