WP1712MFDI50 - Miller Weldcraft A-150 TIG Torch Kit, 12.5ft Braided, 50mm Dinse

Miller Weldcraft A-150 (WP-17) TIG Torch Package - WP1712MFDI50

The Miller Weldcraft A-150 is the evolution of the classic WP-17 air-cooled TIG torch, engineered to provide maximum versatility and operator comfort in a 150-amp package. This specific configuration, SKU WP1712MFDI50, is tailored for welders utilizing power sources with 50mm gas-through Dinse receptacles. It offers a robust solution for light-to-medium duty applications where maneuverability is key, but durability cannot be compromised.

Technical Specifications and Performance

Rated at 150 Amps DC and 115 Amps AC at a 60% duty cycle, the A-150 is capable of handling a wide range of materials including steel, stainless steel, and aluminum. The torch body features a rigid head with a 70-degree angle, ideal for general access and walking the cup. The cooling system relies on the efficient design of the ribbed handle and heavy copper construction to dissipate heat, protecting both the consumables and the operator's hand.

Premium Cable and Connection

A standout feature of this package is the 12.5-foot (3.8 m) Mono-Flex braided power cable. This 1-piece cable assembly combines the power conductor and gas hose into a single, durable line. The braided rubber exterior offers superior abrasion resistance and flexibility compared to standard vinyl tubing, particularly in colder shop environments. The cable is terminated with a 50mm male Dinse connector (gas-through), eliminating the need for separate gas lines or bulky adapters on compatible machines like the Miller Dynasty 210/280/400, Maxstar series, and newer Syncrowaves.

Compatibility and Consumables

The A-150 utilizes the industry-standard Weldcraft 10N Series (3 Series) consumables. This ensures that replacement parts—such as collets, collet bodies, gas lenses, and alumina nozzles—are easy to source and interchangeable with other WP-17, WP-18, and WP-26 style torches. The package comes factory-assembled with a collet, collet body, nozzle, back cap, and a 2% ceriated tungsten electrode, allowing for immediate setup and arc initiation.
