GBH4000-S3 SMART WELDING GATE
GBH4000-S3 SMART WELDING GATE
- Specialized gantry welding equipment for welding steel trusses in steel structure production, flexibly meeting the welding needs from light to heavy beams.
- The GBH4000-S3A gantry welder uses a smart welding head for convenient operation.
- The GBH4000-S3M gantry welder retains the S3 smart welding control system but does not use a smart welding head to optimize investment costs.
Main Features
Let's explore the strengths of the Weldcom GBH4000-S3 intelligent welding gantry – One of the specialized gantry welding devices for welding steel trusses in steel structure production, flexibly meeting the welding needs from light to heavy beams.
Outstanding advantages of the GBH4000-S3 intelligent welding gantry
Sturdy frame with high load capacity
GBH4000-S3 intelligent welding gantry uses a machine frame with a load capacity of up to 2500kg, allowing the product to withstand additional welding sources and wire spools on the machine body, significantly saving wire replacement time.

Advanced modern welding technology
Compared to other machines on the market, GBH4000-S3 applies 3-wire arc welding technology, with two 1.6 wires and one 4.0 wire operating on the principle:
- Thin beams with weld width K≤10: The controller will automatically select two 1.6 wires for welding, ensuring beautiful weld quality, high speed, and low heat generation, reducing beam warping, and minimizing straightening and heating time and costs.
- Heavy beams with weld width K>10: The machine will automatically select three wires, 1.6 and 4.0, with the 4.0 wire going first to create deep penetration, followed by two 1.6 wires for surface coverage, enabling deep penetration welding for thick beams with high productivity, smooth, beautiful welds, and ball screws. Thus, the machine provides high precision in weld profile and position.
Additionally, the MIG welding source used for the gantry is a robot-specific source with many advantages such as a wide input voltage range, stability, and durability. The wire feeder head has an encoder to control wire feed speed, ensuring stable welding current and the highest weld quality.
Smooth weld path with 6 DC single-phase sources
The GBH4000-S3 intelligent welding gantry uses 6 DC single-phase sources, significantly superior to conventional 2-wire 2-arc Tandem gantry welders. Therefore, the machine creates beautiful, smooth, glossy weld paths, free from welding current interference during operation.

Fast speed - Superior efficiency
Bruco's intelligent welding gantry features a 1F welding position, capable of welding straight beam positions, with a maximum beam length of up to 15mm and flange-web thickness from 800 to 1500mm. Notably, the machine's welding speed reaches 1,700 mm/min, reducing beam warping and meeting the delivery schedule requirements of businesses.
Improved controller - Compact - User-friendly
The product's controller is integrated with SMART intelligent technology, offering outstanding advantages to solve business challenges:
Flexible handheld touch screen controller, easy-to-use Vietnamese interface for user convenience.
The controller comes with 200 pre-set welding processes, minimizing worker operations and not requiring high-level experience. Thus, users only need to select the weld size and input information, and the machine will automatically choose the optimal speed and voltage.

The controller can also notify users of any device errors and report them. Moreover, the device can store labor data through machine on/off times, welded beam meters, consumables, error history... Helping accurately assess employee capabilities and work progress.
