This configuration supports a range of pneumatic tools and welding tasks while maintaining a single, transportable footprint for field work and small workshops.
Tomahawk Welder Generator 120A, 2,200W
The Tomahawk unit combines a 120-amp stick weld capability with a 2,200-watt inverter generator, enabling welding and portable power simultaneously. It uses a gas-powered engine to drive the system, delivering a stable sine wave essential for consistent welding performance. The compact footprint supports field fabrication and maintenance work without extensive auxiliary power needs.
HPDMC 13HP Gas Air Compressor with 30 Gal Tank
This HPDMC model provides 13 horsepower gasoline power with a 30-gallon ASME tank and 24 CFM output. The two-stage design supports higher pressure for tool-driven operations in auto repair, construction, and field service. With a truck-mount friendly form factor, the unit emphasizes portability and continuous air supply for pneumatic tools while delivering solid air capacity for demanding tasks.
Tomahawk 15 HP Engine Driven Welder and Generator
The Tomahawk 15 HP machine provides a generator up to 2,000 watts and a 210-amp stick welding capability, designed for integrated field welding. Its engine-driven inverter setup offers a stable sine wave, enabling simultaneous welding and tool operation while maintaining adequate power for common shop equipment and lighting on mobile sites.
Buying Guide
- Power output and duty cycle: Match the generator wattage to your total tool load and consider welding duty cycle to prevent overheating during long runs.
- Air output and tank size: Larger CFM and tank capacity reduce cycling and provide steadier air supply for impact wrenches, spray guns, and grinders.
- Fuel type and availability: Gas engines offer portability without electrical dependencies but require regular maintenance and fuel management on job sites.
- Welding capability: Check maximum amperage and welding type (stick, MIG, TIG) supported; consider whether you need 120V/240V AC compatibility.
- Portability and mounting: Truck-bed or service-vehicle mounting increases mobility; ensure weight, dimensions, and mounting hardware fit your fleet.
- Safety and compliance: Look for ASME tanks and EPA certifications, plus automatic shutoffs or safety valves for high-pressure operation.
- Maintenance and availability of parts: Consider brands with readily available service networks and replacement parts to minimize downtime.
