Bench Welders & Tweezer-Weld

Bench Models

WH1 Series

WH2 Series



tweezerweld_Tw5The TWA-5 has vertical, straight-line motion welding heads. Consistent welds are maintained by the low inertia slides suspended on a cantilever spring, which provides pressure for low interface resistance, and fast follow-up. Also available is theTWA-5AO equipped with pressure gauge, regulator, and electric foot switch to actuate a solenoid valve arrangement.

Type Press Kva Range Up to 5 KVa Electrode Force 7 to 15 lbs. Vernier adjustment Dimensions 9″ H x 2.3″ W x 6½” D Electrode Size 1/8″ Diameter Throat Depth Adjustable 1¾” to 3.0″ Stroke


TW3 Bench Welders Tweezer Weld

These vertical type press heads have universal adjustments incorporated in both electrode holders allowing vertical, lateral, radial, and angular movement of the electrodes. Fixturing,TW3 Bench Welders Tweezer Weld special tooling and automatic machine specifications allow the TWA-3 to be universally used in various welding applications. Also available in the TWA-3AO are options including air cylinder, speed control, air pressure gauge, solenoid valve, 110 volt line control and foot switch.

Type Press Kva Range Up to 20 KVa Electrode Force 8 to 55 lbs. Vernier adjustment Dimensions 13½” H x 3½” W x 13″ D Electrode Size ¼” Diameter Throat Depth Adjustable 6 to 7½” Stroke (Max.) 1¾”(TWA-3) 1″ (TWA-3AO)


TW5D Bench Welders Tweezer Weld

TW5D Bench Welders Tweezer Weld The TW-5D design incorporates dual, straight line motion weld heads. This dual head welder provides consistent welds by utilizing low inertia slides which are individually suspended on cantilever springs. These provide pressure for low interface resistance and fast follow-up. The TW-5D comes equipped with a solenoid, pressure gauge, regulator, and electric foot switch for precise pneumatic actuation.

Independent Precision Slides insure consistent parallel welding accuracy. This design is specifically suited for Battery Tabbing applications.

Kva Range Up to 5 Kva Electrode Force 7 to 15 lbs. Dimensions 8½”W x 9½”H x 8½”D Throat Depth 2 ¼” to 3 ½” Electrode Gap 0.005 to 0.500″ Timer Initiation Micro Switch


TWA6 Bench Welders Tweezer WeldThe TWA-6 is the larger and heavier duty companion of theTWA-3 series that was hailed as the world’s first constant pressure air operated welding head. In operation, when the foot switch is depressed, air pressure from the cylinder actuates the patented cam/cantilever spring assembly and the electrode moves down contacting the pieces to be welded. Only the pressure of the cantilever spring is applied regardless of any variations in the air pressure lines. The weld sequence is initiated by a micro-switch, which is activated by the cantilever spring deflection.

The TWA-6 also features roller bearing slides for true low friction, low inertia performance. This welder is ideally suited to semi-automatic and automatic applications.

TWA-6 Technical Features:
Type Press KVa Range Up to 125 KVa Electrode Force 25 to 250 lbs. Vernier Adjustment Dimensions 27″Hx7.5″Wx13″D Electrode Size No.1 Morse Taper Throat Depth 3.5″ Stroke Up to 2.0″


TWPG-1 Bench Welders Tweezer WeldThe TWPG-1 is designed to convert small weld heads into a dual electrode parallel gap welder. Each electrode is controlled by independent springs to provide equal and consistent pressure at the weld point.

Features include an electrode gap from 0.001″ to 0.062″ using an adjustable knob, which are constructed to TWEEZER-WELD specifications to ensure trouble free operation.

The TWPG-1/TWA-5 assembly mounted to optional adjustable vertical stand.

The parallel gap welding attachment is mounted on a standard Tweezer-Weld TWA-5 weld head creating a dual electrode parallel gap welder.

Standard Tweezer-Weld heads can be easily re-tooled to perform any stand alone application or designed into a semi-automatic or fully automatic welding system. Off the shelf replacement parts make re-tooling easy and reduce down time.
