Heavy Duty Sub-Arc Tractor

Heavy Duty for Welding Fillet and Butt Joints Welding

The Bug-O System’s Submerged Arc welding tractor is outfitted with all of the necessary equipment for performing submerged-arc welding for fillet and butt joints. The integrated wire-feeder and torch provide racking for cross-seam and vertical position fine-tuning. Heavy-duty tractors can travel from 5-100 ipm (127-2540 mm/min). It can carry a maximum payload of 350 lb (159 kg).

The tractor controls are integrated into the wire-feed control unit, providing a seamless interface to the welding process. The machine has strong wire feed welding equipment that can work at speeds from 25 to 600 inches per minute. It can handle wire diameters from 1/16″ to 7/32″ (1.59 – 5.56 mm). The included flux recovery unit recycles the submerged-arc welding tractor flux.

What Is Sub-Arc Welding and Why Use It?

Submerged Arc Welding (SAW) is a high-efficiency process where the weld arc is hidden beneath a layer of flux. This method delivers deep penetration, minimal spatter, and exceptional weld quality—ideal for heavy-duty applications like structural fabrication and tank welding.

Advantages of Using a Welding Tractor for Automated Welds

A welding tractor automates torch travel for consistent, hands-free welds.
Key benefits include:

Improved weld speed and quality
Reduced operator fatigue
Consistent travel on flat or curved surfaces
Adjustable torch positioning
Seamless integration with wire-feed systems

Explore the Capabilities of a Sub-Arc Welding Machine

A sub-arc welding machine combines a power supply, wire feeder, torch, and controls into one efficient unit. Bug-O’s heavy-duty system handles large wire sizes, supports multi-position racking, and recycles flux—all built to perform in high-demand environments.

How a Subarc Welder Improves Efficiency and Precision

Whether referring to the equipment or the operator, a subarc welder is essential for precise, high-volume welding. Bug-O’s system delivers repeatable results with integrated controls, steady wire feed, and optimized travel, making every weld cleaner and more reliable.
