DC Stick Welder – Versatile Field Welding Solution

This unit integrates a professional-grade DC stick welder (SMAW) with an amp range of 180 to 250 amps, making it capable of tackling a wide range of welding applications:

• Equipment repair

• Structural welding

• Pipe welding

• Heavy-duty fabrication

• Field repairs on construction machinery and vehicles

The 120–180 volts of DC power ensures smooth, stable arcs with excellent penetration and minimal spatter, ideal for welding in various conditions.

With a 60% duty cycle at 200A, this welder is built for sustained, heavy-duty operation, allowing professionals to complete larger welding tasks without frequent cooldown periods.

In traditional systems, conventional dig delivers a preset amount of short clearing current to clear a short circuit, which is fixed and does not adapt to changing conditions. In contrast, advanced dynamic dig technology uses a time based algorithm that automatically adjusts the current required for short clearing. This allows the welder to match application, material, fit up, and welder technique, resulting in a smoother, more consistent arc across a variety of welding scenarios.

High-Capacity Generator – Reliable Jobsite Power

The integrated generator provides up to 5,500 max watts and 5,000 running watts, sufficient to power:

With this level of output, the unit can simultaneously run pneumatic tools, welding operations, and electric equipment, making it a true all-in-one jobsite powerhouse.

The single integrated system saves valuable space on service trucks and trailers and eliminates the need to transport multiple separate machines.

Rugged Design and User-Friendly Features

Built to endure the rigors of field work, the Case IH Air Compressor and Welder features:

• Heavy-duty frame to withstand impacts and rough handling

• Compact footprint for efficient installation on service vehicles, trailers, or workshops

• Accessible controls conveniently located for easy operation directly at the operator's fingertips for compressor, welder, and generator functions

• Integrated control panel for monitoring system status, voltage, and pressure

• Stable base to minimize vibration during operation

The design also allows for quick and easy servicing, minimizing downtime for routine maintenance and engine checks.

Accessories and Interfaces

To maximize the performance and convenience of engine driven welders, a range of advanced accessories and interfaces are available. The ArcReach system stands out as a must-have for professionals, enabling users to change weld settings and control the machine remotely from their work area. This full remote control capability means less time walking back and forth, and more time focused on welding.

For those working with aluminum or in demanding industrial environments, the ArcReach Smart Feeder system delivers exceptional results, especially when paired with a compatible power source like the Dimension, XMT, or an engine-driven ArcReach unit. This system ensures precise control and a consistent arc, even in challenging applications.

Maintaining clean, dry air is essential for air tools and pneumatic systems. A regenerating inline air dryer system eliminates moisture from the air stream, preventing tool freeze-ups in cold climates and ensuring reliable operation. Protective covers, specifically designed for models like the Big Blue 600 Air Pak/800 Series with Deutz, safeguard your investment from the elements and jobsite hazards.

Modern engine driven welders also feature user-friendly interfaces such as industrial USB ports. These allow operators to download machine log files, retrieve in-depth information, and update to the latest software, making machine management and maintenance more efficient. The ability to track oil change intervals, engine hours, and machine statistics, as well as display engine diagnostics, helps prevent overheating and ensures your system remains in peak condition.

With these accessories and interfaces, you can keep your engine driven welder, air compressor, and power tools running smoothly, while maintaining full control and easy servicing on any jobsite.
