SUA Straight Line Oxy-Fuel Motorized Cutting and Beveling Machine

In this review the SUA HK-12 Beetle is assessed as a portable oxy-fuel cutter built for straightforward, heavy-duty plate work. The bottom line: this motorized track machine is for fabricators and maintenance crews who need repeatable straight and bevel cuts in medium to very thick steel, and its biggest selling point is the combination of precision guidance and wide cutting capacity. The review finds the unit delivers accurate, clean cuts across a wide thickness range while remaining compact and transportable for jobsite work.

Key Features

• Precision Flame Cutting: The guided motorized carriage produces consistent straight and bevel cuts so operators can rely on repeatable edge quality for fit-up and fabrication.
• High Cutting Capacity: Capable of cutting steel plates from 6 to 100 mm thick when paired with the correct cutting tips, making it suitable for structural and heavy maintenance tasks.
• Included Cutting Tips: Ships with three Oxy/Acetylene G02 tips (#1, #2 and #3) compatible with common Koike systems, so you can start cutting without ordering extras.
• Adjustable Cutting Speed: Automatic speed control from 50 to 750 mm/min lets users dial feed rate for cleaner cuts on thin plate and slower, deeper cuts on heavy sections.
• Portable Construction: Built from high-strength aluminum alloy, the compact frame keeps weight down for transport between shops or sites without sacrificing durability.
• Fuel Flexibility: The unit can be adapted to oxygen/propane operation with G03 oxy/propane tips (sold separately) for operators who prefer propane.

Who It's For

The HK-12 Beetle is aimed at metalworkers, structural fabricators, and field maintenance teams who need a portable straight-line oxy-fuel cutting solution that handles a wide range of plate thicknesses. Its motorized carriage and speed control suit production runs where repeatable cuts and bevels save setup time and downstream welding work.

Those who should look elsewhere include buyers who need plasma-level finish on thin stainless or nonferrous metals or who require an integrated track in the base purchase; the listed configuration is the no-track version and additional tracks are sold separately.

Pros & Cons

Pros

• Wide thickness capability (6 to 100 mm) covers most heavy fabrication and repair jobs.
• Included G02 oxy/acetylene tips let you begin cutting immediately with compatible torch systems.
• Automatic speed range from 50 to 750 mm/min provides flexibility for varied materials and cut profiles.
• Aluminum alloy construction keeps the unit portable while remaining sturdy for jobsite use.

Cons

• The package shown is the no-track configuration, so buyers needing integrated rail must purchase tracks separately.
• Propane compatibility requires separate G03 tips, which are not included.
