OVERVIEW

Heavy-Duty Weldcraft W-280 Torch Package

Maximize the potential of your TIG welding operations with the Miller 300990 W-280 Water-Cooled Torch Package. This all-inclusive kit is built around the renowned Weldcraft W-280 (WP-280) torch, which is engineered to deliver 280 amps of continuous DC welding power at 100% duty cycle. The W-280 is a favorite among industrial welders for its ability to handle heavy-duty applications while retaining a lightweight and ergonomic form factor. The water-cooling efficiency is enhanced by the torch's internal design, which maximizes surface area contact with the coolant, keeping the handle and head cool even during the most demanding multi-pass welds.

This package is not just a torch; it is a complete system upgrade. It includes a 25-foot torch cable assembly, giving you the reach required to work on large assemblies or move around a fixture table without repositioning the power source. The kit also features a premium Smith regulator/flowmeter, widely regarded as the industry standard for accuracy and durability. A 15-foot 1/0 weld lead with a secure work clamp ensures that your ground connection is as reliable as your arc. The addition of a protective cable cover helps organize your leads and prevents damage from hot surfaces or sharp edges in the shop environment.

For added value, the package includes the AK4C accessory kit. This consumable starter pack contains a versatile selection of back caps, collets, gas lenses, and tungsten electrodes, allowing you to tackle a variety of joint configurations right out of the box. The Dinse-style connectors ensure a quick, twist-lock connection to compatible power sources like the Dynasty 200/280/350/700 and Maxstar series. If you are looking for a rugged, reliable, and complete water-cooled setup, the Miller 300990 delivers professional-grade performance that stands up to the rigors of daily industrial use.

FAQ

This kit is designed for Miller machines with 50mm Dinse receptacles, including the Maxstar and Dynasty 200, 280, 350, and 700 series, as well as Syncrowave 250 DX and 350 LX models.

No, the 300990 kit does not include a foot control. It includes the torch, leads, regulator, and consumables. Foot controls are sold separately.

The Weldcraft W-280 torch is rated at 280 Amps DC at 100% duty cycle, making it suitable for continuous industrial welding.

The W-280 included in this package is a water-cooled TIG torch. You will need a water cooler (sold separately or integrated into your machine) to operate it safely.

The AK4C kit includes a variety of shielding cups (nozzles), collets, collet bodies, and 2% ceriated tungsten electrodes in sizes 1/16, 3/32, and 1/8 inch.

The TIG torch cable is 25 feet (7.6 meters) long, and the work lead (ground cable) is 15 feet (4.6 meters) long.

Yes, it includes a Miller | Smith HM2051A-580 regulator/flowmeter and the necessary gas hose to connect to the machine.

The W-280 offers higher amperage capacity (280A vs 200A) while maintaining a relatively compact size, allowing for heavier welding applications without sacrificing too much maneuverability.
