• Precision straddle ball bushing and dual cam roller ram guide system of long term electrode alignment and minimum dynamic friction.
• Precision calibrated pre-compressed spring weld force system with micrometer readout scale for maximum reset ability.
• Weld force firing switch to assure application of electrode force before current flow initiation.
• Low inertia upper electrode ram structure for superior follow-up on extremely short weld times.
• Adjustable-rotatable horns for versatile electrode configuration capability.
• High strength socket head cap screw electrode clamping hardware to resist head stripping in repeated use.
• Transformer cable mounting studs to isolate electrodes from cable magnetic impulse.
• With accelerator foot treadle and pull chain.
• Lever-operated for minimum operator fatigue.

• These bench mounted welders consist of a cast main frame mounted on a tubular support column. The column passes through a hole in the bench top and is supported by the welder base. This provides vertical adjustment of the lower horn and upper electrode holder. Height of machine above bench top is also adjustable.
•  The upper electrode is attached to a copper alloy holder; a flexible copper band connects the upper holder to the rear terminal which provides the means for attachment of the welding transformer cable.
• The lower horn holds the lower electrode in a vertical positions or at desired angular positions. The horn may be swung to either side and is adjustable in or out. The lower horn has a terminal pad for attachment of the transformer cable.
•  A precision type firing switch is actuated by compression of the weld force spring which assures that proper weld force is applied prior to control firing.
•  Low friction bearings and low inertia of moving parts assures high quality welding on critical jobs. EB-1 Operation: (Foot Operated Only)

EB-1 welder an operating rod, which moves up and down through the tubular column, is attached to a lever in the welder frame which in turn transmits vertical movement to a non-rotating outer quill. When the operating rod is pushed upward, the outer quill is moved downward until the upper electrode contacts the work. This upper electrode is attached to a low inertia inner quill operating in oilite bushings. A downward pressure is exerted on this inner quill by a graduated pressure spring which determines the actual welding force.. By means of mechanical linkages maximum welding force with very little muscular effort is obtained. Such linkage action permits rapid approach of the upper electrode to the work, controlled deceleration and contact on the work without impact. The foot operating mechanism consists of a swinging type treadle, adjustable to individual leg length and angle requirements. A bicycle type pedal permits natural leg motion for high-speed production.

EBA-1-1/2: Operation: (Air Operated) In the EBA-1-1/2 welder the upper electrode is clamped to an operating ram having hardened and ground guide surfaces. These surfaces are contacted by sealed adjustable antifriction roller bearings, assuring a smooth low friction vertical motion of the ram, necessary for precise welder operation. These welders are ideal for projection welding when fitted with tooling platens. The air operating mechanism is mounted on top of the welder frame and consist of an air cylinder with a screw adjustment for setting the stroke of the welder head. It is also equipped with an air filter, oil fog lubricator, solenoid operated 4-way air valve and exhaust muffler. A foot switch is provided to initiate the welder operation. A foot operating mechanism is available on request as a special extra cost option.

Bench Type - Invertor or AC Spot/Projection Welder
This inverter welding head is so revolutionary we had to give it a special name. Atop the low inertia ram you'll find a patented accelerator that gives the "Blue Goose" the best follow-up action in the welding industry. This makes it an ideal machine for cross-wire welding, and other spot and projection welding applications. It lays down low impact, high-speed welds with exceptional repeatability andvirtually no deflection.

FLASH-BUTT WELDERS / click here for more information.

Flash-Butt welding is a process designed to produce a forge-type butt weld between two metal pieces of similar shape. It is used to join ends of rods, bars, strips, rings, tubes, forgings and fittings.

The pieces to be joined are clamped in fixtures which are connected to the secondary of a welding transformer. One of the clamp fixtures is mounted on a slide which is programmed to move toward the stationary clamp at a controlled rate.

During this movement the transformer is energized and as the workpieces touch, welding current flows. This flash process generates heat in the workpieces.

At the proper temperature the slide driving mechanism rapidly accelerates, forging the work pieces together to form a joint essentially as strong as parent metal without the aid of any filler material.

This "upsetting" action forces impurities out of the weld zone. Thus the inner weld metal is sound and free of oxides or cast metal.

SEAM WELDERS / click here for more information.

The main frame of these seam welders is of heavy, rigidly reinforced welded steel construction for a minimum of mechanical deflection but a maximum of accessibility and neat appearance. The lower conductor support or knee is a heavy steel fabrication keyed to the frame for accurate vertical adjustment. The upper conductor is insulated from the frame, while the lower conductor is grounded to the frame, therefore work support tables or conveyors can also be grounded.
