91101105 - Tweco A-14-HD 400A Stick Electrode Holder

Industry Standard Heavy-Duty Electrode Holder

The Tweco A-14-HD (Stock No. 9110-1105) is a testament to the enduring quality of the Twecotong line, representing the industry standard for manual arc welding electrode holders. Designed for heavy-duty industrial applications, this holder is rated for 400 Amps, making it suitable for a wide range of structural and fabrication tasks. The "HD" designation signifies its robust construction, engineered to withstand the rigors of daily shop and field use while maintaining optimal performance.

At the core of the A-14-HD is its high copper alloy tong construction. Unlike lesser holders that may rely on steel or lower-grade alloys, Tweco utilizes a specialized copper formulation that maximizes electrical conductivity. This ensures that the current from your welding machine is transferred efficiently to the electrode, minimizing resistance and heat buildup within the holder itself. The result is a cooler-running tool that allows the welder to work longer without discomfort or the need for frequent cooling breaks.

One of the standout features of the Twecotong design is the use of Super-Mel insulation. The A-14-HD features reversible top and bottom insulators. When the contact surfaces eventually show signs of wear from spatter or heat, the operator can simply remove, flip, and reinstall them, effectively doubling the service life of these consumable parts. This design consideration significantly reduces long-term maintenance costs. The holder utilizes a ball-point cable connection, a secure mechanical method that aggressively locks the cable strands against the holder body, ensuring a solid electrical connection that resists loosening over time. Accommodating cables from 3/0 to 4/0 and electrodes up to 1/4 inch, the A-14-HD is a versatile powerhouse for any professional welding setup.
