91101110 - Tweco A-316 Tong Style Electrode Holder - 250A - Master Pack

Technical Overview: Tweco A-316 Electrode Holder (Master Pack 24)

The Tweco A-316 Electrode Holder (SKU: 9110-1110) is a copper-alloy tong-style holder designed for Shielded Metal Arc Welding (SMAW). This product listing represents a Master Pack of 24 units, intended for high-volume fabrication environments, educational institutions, or inventory replenishment. The A-316 is rated for a welding current of 250 Amperes at a 50% duty cycle, making it an ideal choice for general fabrication and medium-duty repair work.

Technically, the holder features high-conductivity copper alloy tongs that minimize electrical resistance and heat buildup. The jaw design incorporates a 6-position pattern, allowing the welder to orient the electrode at various angles (45°, 90°, etc.) to access difficult joints. The unit accommodates electrode diameters up to 3/16 inch (4.8 mm). The cable connection utilizes a ball-point screw mechanism, which secures the welding cable strands effectively against the holder body, ensuring optimal conductivity. It is designed to accept welding cables up to size 1/0.

A key engineering feature of the Tweco A-Series is the reversible top and bottom insulators. Made from a thermoset fiberglass compound, these insulators protect the metal tongs from accidental arcing. When the contact surfaces wear, the operator can simply remove and reverse the insulators to expose a fresh surface, effectively doubling the service life of these consumable parts. The internal spring is fully insulated and protected from spatter, maintaining consistent jaw tension over the tool's lifespan.
