DC-IV MAX

Overview

The BUG-O DC-IV MAX is a turnkey mechanised cutting solution designed for off-table, repeatable beveling and vertical cutting. It combines a purpose-built BUG-O tractor and controller with compatible Hypertherm® Powermax® and MAXPRO® plasma cutting systems, creating a practical platform for fabricators who need precise, portable and repeatable plasma cutting performance.

Unlike fixed table cutting systems, the DC-IV MAX brings the cutting machine to the workpiece. This makes it especially useful for large plates, field work, structural fabrication, repair operations and production environments where material handling is costly, slow or impractical.

The system is engineered around controlled motion, accurate torch positioning and simplified setup. Features such as ONETOUCH® start, integrated start delay, Process Stop Control, heavy-duty racking, manual bevel and lead/lag angle adjustment, built-in degree dials and torch breakaway with automatic process stop help operators achieve cleaner, more repeatable cuts with less manual variability.

Recommended options and accessories

1. Pendant 100-0695: Field or factory-installed pendant option for remote control of the system.
2. Limit Kit 100-0697: Halts motion and cutting when the limit is reached. Useful for unattended end-of-plate shutdown when built-in auto stop is not supported, such as in arc gouging or cutting mesh.
3. Optional Torch Holder 100-0598: 1.39″ diameter torch holder for standard 1 3/8″ torch diameter and standard oxy-fuel torch diameter. Includes slot to accommodate torches with rack.
4. Optional Torch Holder 100-0608: 1.43″ diameter torch holder suitable for Hypertherm® 105 torch applications.
5. Optional Torch Holder 100-0783: 2.02″ diameter torch holder assembly, available for torch configurations with or without rack.
6. Spare Parts Kit 100-0698: Recommended for maintenance readiness and reduced downtime.
7. Pendant Cable GOF-4160-XX: Required when using the pendant. Available in 10 ft, 15 ft, 25 ft and 30 ft lengths.
8. Oxy-Fuel Kit 100-0699: Dual-voltage solenoid kit for oxy-fuel cutting applications over 2″ / 50.8 mm. Torch and longer 3-hose assembly are ordered separately or supplied by the customer.
9. Pelican Case 100-0714: Hard-shell case for safer transport, shipping and storage.
10. ARR-1080 Heavy Duty Aluminium Rigid Rail: 8 ft rail commonly used with the DC-IV MAX.
11. ARM-2010 Rare Earth On/Off Magnet: Magnetic rail support for securing the rail to ferrous workpieces.
12. ARM-2015 Spacer Bar: Spacer bar used with ARM-2010 magnet assemblies.

Technical advantages

The DC-IV MAX is designed to remove guesswork from beveling and vertical plasma cutting. By combining a dedicated tractor, controller, torch alignment guide and plasma-system integration, the machine helps operators set up repeatable cutting conditions without relying only on manual torch handling.

The ONETOUCH® function starts both the tractor and plasma system with a single action, while the integrated start delay allows the arc to transfer before travel begins. This is critical for cleaner starts and more consistent cut quality. The Process Stop Control system also improves operational control by stopping the entire process automatically when the cut is complete.

The heavy-duty racking system improves mechanical stability, while the independent bevel and lead/lag angle controls allow two-dimensional angle adjustment. Built-in degree dials make those adjustments easier to repeat, which is valuable when multiple bevel cuts need to be performed with consistent geometry.

The torch breakaway with automatic process stop adds an important protection layer. If the torch is disturbed or impacted, the system can stop the process, reducing the risk of torch damage, defective cuts or uncontrolled operation.

Applications

The BUG-O DC-IV MAX is suitable for fabrication environments where repeatable off-table cutting is required. It is particularly useful when plates or workpieces are too large, too heavy or too inconvenient to move to a fixed CNC cutting table.

Typical applications include plasma bevel cutting, vertical plasma cutting, plate cutting, weld preparation, edge preparation, structural fabrication, tank and vessel work, field fabrication, repair work, shipbuilding, heavy equipment maintenance and industrial cutting operations.

With the optional oxy-fuel accessory, the DC-IV MAX can also support cutting applications over 2″ / 50.8 mm, extending its usefulness beyond standard plasma cutting requirements.

Why choose DC-IV MAX

The DC-IV MAX is a strong choice for companies that want table-like cutting consistency without depending entirely on a fixed cutting table. It gives fabricators a portable mechanised cutting platform that can be moved directly to the workpiece, reducing material handling and improving workflow flexibility.

Its value is not only in cutting motion, but in process integration. The machine coordinates tractor movement, plasma start, start delay, process stop, torch alignment, bevel control and speed control in one practical package. This makes it easier to achieve repeatable results, especially in environments where skilled manual cutting is slow, tiring or inconsistent.

For workshops and field teams, the commercial advantage is clear: faster setup, less downtime, improved cut quality, lower rework, reduced grinding and better productivity in beveling and cutting operations.
