SPOT AND PROJECTION BENCH WELDING MACHINES

SPOT AND PROJECTION BENCH RESISTANCE WELDING MACHINES 16kVA..150kVA

Resistance spot and projection bench welders 2101D..2144D-2102N, nominal power at 50% of continuous current from 16kVA to 150kVA.

Microprocessor control with direct reading of welding current (excluding electric spot welder 2101N).

Heavy-duty, long-life chrome-plated steel cylinder and rod; adjustable anti-rotation device.

Pneumatic components requiring no lubrication against mist emission into the environment.

Key-operated double stroke cylinder (resistance welding machines 2121D..2144D).

Regular compressed air filter unit included in the machine, compressed air supply disconnector.

Two-stage electric foot pedal for clamping workpieces and welding them only when correctly positioned.

Provision for connection of an additional two-stage electric foot pedal for welding with direct recall of welding programme no. 2 (excluding electric tackers 2101D..2102N..2103D and machines equipped with options 2161 and 2181).

Welding transformer, plates, electrode holder and electrodes made of water-cooled copper alloy; resin-encapsulated windings.

Synchronous control with cooling water-isolated SCRs and protection thermostat.

Two-hand control with timer for maximum safety and removable key switch provided for all models (except welding machine 2102N).

The two-hand control is standard on projection welders only, optional on spot welders.

The benchtop resistance welding machines 2101D..2103D..2144D are prepared for connection of the dual control.

FAQ and insights

Electrical resistance welding is a process of joining metals using heat generated by the electrical resistance of the material itself. The parts to be joined are placed in contact with each other and passed through by an electric current. The passage of current generates heat that melts the metal in the contact zone, thus creating a permanent joint.

Electrical resistance welding offers several advantages over other welding methods, including:

  • High joint strength and reliability

  • High production speed

  • Low heat input

  • Clean and slag-free process

  • Possibility of welding different metals

     

Electric resistance welding is used in a wide range of industrial applications, including:

  • Auto Body

  • Household appliances

  • Metal construction

  • Railway industry

  • Electronics manufacturing
