Spot Welding

Spot Welding

Input Supply Output Type Output CC or CV Works on Power

Salient Features :

  • Transformer : Low leakage (High linkage) design, proper cooling and insulation including winding varnishing by vacuum pressurized impregnating system to enhance reliability and service life.
  • Current Control : Current setting fram min. to max. can done by 6 pasition, off load tap changing switch.
  • Time Control : Solid State Electronic timer to control weld time from 5 to 50 cycles and ‘1 to 10 seconds to achieve accurate and repeatable spots.
  • WELD PRESSURE : Adjustable max. Pressure levels are derived from a heavy-duty compression spring mounted an a pressure rod with adjustable nut. Here is a special arrangement in the machine-minimises operator fatigue and ensures simple setting.
  • COOLING : Electrades, and arms are provided with water cooling arrangement with hose connections. (Water supply & coolant pump to be arranged by the user.)
  • ELECTRODES : One pair of Morse Taper 2 straight electrodes made fram hardened copper-alloy is supplied with the equipment. Other types of spare electrodes can be supplied on specific orders.
  • CABINET : Modern looks, novel design concepts. Epoxy powder coated body for rust free long life.

Scope & Applications

  1. “VULCAN” Pedal operated Rocker arm type spot welding machines are offered in 6,8,10 and 15 KVA models, each with three standard throat depth to cover practically all applications. All machines are made of steel fabricated rigid structures to eliminate the minutest spot deflections. Low leakage design, proper cooling and insulation.
  2. Current setting from min. to max. value can be done by 6 position, off toad Rotary type tap switch. Solid State Electronic timer to control weld time from 5 to 50 cycles and 1 to 10 seconds to achieve accurate and repeatable spots. Electrodes, holders and arms are provided with water cooling arrangements with hose connections.
  3. Spot welds may be made one at a time or several welds may be completed at one time, depending on the number of electrodes used. To dissipate the heat and cool the weld as quickly as possible, the electrodes are generally water-cooled.
  4. Spot welders are utilised extensively for welding steel and when equipped with an electronic timer, can be used for other commercial metal such as aluminium, copper, and stainless steel. They are also very effective for welding galvanised metal.
