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

The Industry Standard for 500 Amp Stick Welding

When you are burning large diameter rods all day, you need a stinger that can take the heat. The TwecoTong A-38HD is the legendary 500 Amp holder designed for professional welders who demand reliability. Known for its superior grip and conductivity, this holder features heavy-duty copper alloy jaws that bite down hard on electrodes up to 3/8 inch thick, ensuring the rod stays exactly where you point it, even in out-of-position welds. The A-38HD is the workhorse of the Tweco line, built to handle the high current required for thick plate welding without overheating your hand.

Comfort and economy are built right into the design. The ergonomic handle is designed to fit comfortably in a gloved hand, reducing fatigue during long shifts. One of the best features for the daily user is the reversible insulator system. When the top or bottom insulators eventually wear down from heat and spatter, you don't have to toss them immediately—simply flip them over to get a fresh surface, saving you money on consumables. The internal spring is shielded from spatter, ensuring the jaw tension remains strong over years of use.

Installation is straightforward with the ball-point cable connection, which aggressively locks down on 4/0 cable for a connection that won't wiggle loose. If you are welding structural steel, pipelines, or heavy machinery, the Tweco A-38HD gives you the confidence that your equipment won't fail when the pressure is on. It’s a classic tool that has earned its place in toolboxes across the world for a reason: it just works.
