91101106 - Tweco A-38HD 500A Stick Electrode Holder

Heavy-Duty Conductivity for Industrial Fabrication

The TwecoTong A-38HD Electrode Holder is a premier choice for heavy industrial manual arc welding. Engineered with high-conductivity copper alloy tongs, this holder is rated for 500 Amps, making it suitable for the most demanding SMAW applications. The 'HD' designation signifies its heavy-duty construction, designed to withstand the thermal and mechanical stresses of continuous high-amperage welding. It accommodates electrodes up to 3/8 inch (9.5mm) in diameter, providing versatility for structural steel, shipbuilding, and heavy equipment repair.

A key engineering feature of the A-38HD is its efficient cable connection system. It utilizes a ball-point cable connection that secures up to 4/0 welding cable, ensuring minimal resistance and maximum current transfer to the arc. The holder also features fully insulated springs, protected by a molded insulator to prevent arcing and extend the internal mechanism's lifespan. The design prioritizes longevity and ease of maintenance, featuring reversible top and bottom insulators made from high-impact, heat-resistant material. This reversibility effectively doubles the life of these wear parts, offering a lower total cost of ownership for industrial operations.

Weighing approximately 30 ounces and measuring 13 inches in length, the A-38HD balances substantial build quality with operator control. The handle is shaped to provide a secure grip while insulating the welder's hand from the heat generated during prolonged welding sessions. Whether used in field construction or shop fabrication, the TwecoTong A-38HD delivers the consistent performance and durability required by professional welding standards.
