Electrode Holder for Stick Welding

The Tweco A-316 is a clamp-style electrode holder rated at 250 A for heavy-duty stick welding (SMAW). It accepts electrodes up to 3/16 in diameter and uses a copper alloy jaw for conductivity. The 6-position jaw allows multiple angle settings. Overall length is 9 1/4 in.

Cable and Jaw Compatibility

Verify that your welding cable gauge matches the 2/0 wire gauge specification for the ball point screw connection. Confirm the holder jaw material suits your electrode type and diameter range. Ensure the 6-position jaw articulation covers the angles required for your joint configurations.

Thermal and Electrical Performance

The copper alloy jaw conducts current efficiently at the 250 A rating during normal stick welding duty. Heat builds in the jaw and cable connection under sustained heavy-duty cycles. The ball point screw connection must remain tight to minimise resistance and localised heating.

Questions about this item

What comes with the Tweco A-316 electrode holder and what must be purchased separately?

The holder includes the clamp-style body with copper-alloy jaws and a ball-point screw connection for 2/0 cable. Welding cable, electrodes and a power source are not included.

How do I choose between the A-316 and other Tweco holders for my application?

Select the A-316 when you need a 250 A heavy-duty clamp with a 6-position jaw for electrodes up to 3/16 in and a 9 1/4 in overall length for stick welding.

What does the 250 A rating mean when the holder is used on a real stick-welding machine?

It indicates the maximum continuous current the copper-alloy jaws and ball-point connection can carry at the rated duty cycle without overheating during SMAW.
