Pneumatic Spot Welding Machine

Electroweld industries is a leading manufacturer of resistance welding equipment, serving the industry for over 45 years. Our welding machines are designed to provide a production solution at an affordable price while ensuring reliability and low cost maintenance.

Applications: 

• Spot / Projection Welding, Electro-Brazing, Cross Wire Welding, Sheet Metal- 2-ply or Multi-ply, Mark-less Welding, Resistance Heating and Soldering. Capable of Welding Low Carbon Steel,High Carbon Steel,High Strength Steel,Nickel Alloy,High-Temp Alloy,Titanium. Confirmation of weldability of other materials can be provided on request.
• Users Include: General engineering work-shops, makers of furniture, electrical instruments, containers, barrels and drums, telephone, radio communication devices, clocks, kitchenware, textile machinery and spares, automobiles, bicycles, motor-cycles, scooters, auto-ancillaries, toys, air-conditioners, refrigerators, transformers, motor, switch gear, etc.
• Construction : Heavily fabricated with streamlined appearance, suitably stiffened at points of stress. The transformer is mounted directly on to the body and the bearings for the arm are provided in the same.
• Cooling System: Electrodes, Electrode holders secondary water cooled, water required to be free from residue forming impurities and at a temperature of less than 30* C or 85* F. If water temperature is higher, increased water flow is required.
• Electrodes: One pair Morse Taper II straight electrodes supplied as standard with the machine, Other types available on request.
• Adjustment of Electrode Force : By means of Air Pressure. The force is adjustable and gives a constant force from 1-5 Kg Cm!by Pneumatic Cylinder, adjusted by Regulating Valve.
• Adjustment of Electrode Stroke: By vertical adjustment of electrode holder.
• Current Control: By means of fine setting through controller
• Weld Initiation: By means of Foot Switch which initiates the weld only after preset pressure is built up.
• Electronic Control: Electroweld Forwel Constant Current Controller AK-54. The controller supplies stable welding current by secondary feed-back constant current method. Thus maintaining the current as per Set Valuethroughout the welding process.Using a toroidal coil, the current wave form is reconstructed from the output signal. It is then transformed into an RMS effective value. The controller then compares this effective value with the set current value. The weld current is corrected with every half cycle through phase conversion and trigger pulse oscillation. The result is a smooth, consistent secondary welding current delivered at the weld regardless ofthe line voltage fluctuations.
