301311 - Miller 301311 TIG/Stick Contractor Kit with A-150 Torch & RCCS-14 Remote

Technical Overview: Miller 301311 Contractor Kit

The Miller 301311 Contractor Kit is a comprehensive accessory assembly engineered for use with Miller power sources featuring a 14-pin receptacle and 50mm Dinse-style output terminals, such as the Maxstar 210 and Dynasty 210 series. This kit integrates the essential components required for both Gas Tungsten Arc Welding (GTAW) and Shielded Metal Arc Welding (SMAW), centered around the industry-standard Weldcraft A-150 air-cooled torch platform.

Weldcraft A-150 (WP-17) Torch Specifications

The included A-150 torch is a 150-amp, air-cooled model designed for general-purpose fabrication. It utilizes the standard 3-Series (10N) consumables, ensuring widespread availability of replacement collets, collet bodies, and nozzles. The torch body features a ribbed handle design that promotes cooling air circulation, keeping the handle temperature manageable during extended use. The 25-foot (7.6 m) one-piece power cable combines the power conductor and gas passage, reducing bulk and improving flexibility compared to two-piece systems. The torch connects via a standard 50mm Dinse adapter, ensuring a solid electrical connection with minimal resistance.

RCCS-14 Remote Contactor and Current Control

A key technical feature of this kit is the RCCS-14 remote control (Miller Part #043688). This device provides remote on/off contactor control and full-range current adjustment via a 14-pin Amphenol plug. The control mechanism is a rotary potentiometer operated by the thumb or fingertip, allowing the welder to initiate the arc and ramp amperage up or down during the weld cycle. This is critical for crater elimination and heat management in position welding where foot pedals cannot be utilized.

Gas Delivery and SMAW Components

Gas regulation is managed by a Smith flow gauge regulator, capable of delivering accurate shielding gas flow rates from 10 to 50 CFH. It connects via a 12-foot gas hose with standard 5/8"-18 RH fittings. For SMAW applications, the kit includes a 200-amp electrode holder and a 300-amp work clamp, both fitted with 15-foot leads and Dinse connectors. The inclusion of the AK2C accessory kit provides the initial set of consumables, including collets, nozzles, and tungsten electrodes, allowing for immediate equipment commissioning.
