Addressing issues such as insufficient spring tension, poor rebound performance and unstable hovering found in traditional spring-loaded welding booms on the market, Xutai Machinery has independently developed a new-generation balancing system. This system utilises high-grade manganese steel and thickened steel wire to manufacture high-strength springs, significantly enhancing spring flexibility and rebound capacity.

The upgraded spring system automatically balances itself according to the weight of the wire feeder, ensuring stable suspension of the SPT-305 spring welding boom. This prevents the equipment from sinking, springing up or swaying, making welding operations easier and smoother.

● High-strength spring balancing system

Manufactured from high-quality manganese spring steel, it offers high load-bearing capacity, stable spring return, and is resistant to fatigue and deformation even after prolonged use.

● Single-arm Structural Design

Compact in structure and with a small footprint, it is suitable for various welding station layouts.

● 3 meters Working Radius

With a boom length of up to 3 meters, it offers a wide coverage area to meet the requirements of most welding stations.

● 180° Rotation

No electric drive is required; the unit can be freely rotated 180° left or right and adjusted for height simply by pushing it, ensuring flexible and convenient operation.

● Centralised suspended wire feeding system

The wire feeder, welding torch and cables are all suspended and managed in a unified manner, keeping the workstation tidy and enhancing operational safety.

● Compatible with barrel welding wire

Supports the use of barrel welding wire, reducing the need for frequent spool changes and improving continuous welding efficiency.

● Reduced physical strain

Effectively alleviates the impact of the weight of the welding torch and cables on the operator, improving the welding working environment.

The SPT-305 spring welding boom offers two installation options to suit workshop conditions and production requirements: free-standing column mounting and workshop steel beam mounting.

● Free standing column installation does not require attachment to the factory structure, offering flexible layout options and making it suitable for new or standalone welding stations;

● Steel beam installation, on the other hand, is fixed directly to the workshop’s steel structure or steel beams, effectively saving floor space and improving the utilisation of the factory premises.

Both installation methods ensure the stable operation of the welding boom, meeting the requirements of various welding production lines and workstations.

● Xutai Machinery’s welding booms are finished using a pure electrostatic powder coating process.

● We are available in a range of colors including yellow, orange and green.

● Should you require any other colors, simply provide the relevant colour code and we will produce them to your specifications.

How is the load-bearing capacity of the SPT-305 spring welding boom tested?

1. Static load test

Install the SPT-305 spring welding boom in position, attach the standard weight assembly, and apply loads in stages from the rated load to 1.25 times the rated load to 1.5 times the rated load, allowing the structure to stand for 10–30 minutes.

Observation: No plastic deformation, no cracks in the welds, no structural deformation, and no abnormal noises.

If none of the above conditions are present after 30 minutes, the product is deemed to have passed.

2. Dynamic Test

The SPT-305 spring welding boom is repeatedly raised and lowered, rotated 180°, and started and stopped under the rated load to check for any vibration, looseness or fatigue cracks. If none of the above issues occur during one hour of dynamic testing, the product is deemed to have passed inspection.

Once the above static and dynamic tests meet the acceptance criteria, the quality control department applies labels and affixes a certificate of conformity, and the product is released for market distribution.

The Xutai Machinery SPT-305 spring welding boom is widely used in:

● MIG/MAG gas-shielded welding stations

● CO₂ gas-shielded welding production lines

● Automotive component welding

● Sheet metal welding and fabrication

● Construction machinery manufacturing

● Hardware production lines

It is particularly suitable for welding scenarios involving small workpieces, large batch sizes and long continuous production runs.

Xutai Machinery has established a strong presence in the field of welding auxiliary equipment, continuously optimising the performance of its SPT-305 spring welding boom and wire feeder arm. Drawing on our independently developed high-strength balancing system, stable and reliable structural design, and extensive industry experience, we provide customers with more efficient, labour-saving and safe welding station solutions.
