Key Features of Seam Welding Machine with Digital Timer

• The machine body is made out of Reinforced Fabricated Steel Structure with good ventilation
• The upper & lower arms are robust type fabricated from heavy section.
• The main Transformer is housed in the Basic Body
• Heavy duty Transformer is made as Per IS - 4804 Part I as the Main Power Source.
• Copper pipes can be used as secondary segments in which water will be passed for water cooling.
• The insulation of the Transformer is of class F to withstand Temperature up to 155 ° C
• The coil assembly is varnished in F 50 varnish & vacuum impregnated.
• Special Thermo switch to cut-out the Control circuit when the Temperature rises above the safety level protecting the Transformer from Overloading
• Upper & lower weld Wheel assembly consists of Copper alloys suitable section of hardness 68 Rockwell B scale
• Weld Wheel shafts, high percentage of Copper content phosphor Bronze bushing & Water cooled holder are of ample section copper alloy casting.
• The pneumatic systems consists of a pneumatic double acting cylinder, solenoid valves of 4 way 5 port, Filter, Lubricator, regulator, gauge & Foot operating initiating switch for solenoid coil
• Air regulator knob is provided for varying Electrode Force
• All the current carrying components are internally water cooled. The upper & lower bus bars should be provided with built in water Jackets
• Electrode drive system consists of a Motor with thyristorised Speed Control Unit.
• Electronics Control System should be housed in a desk type control cabinet. All the control knobs should be housed, so as to prevent the Misuse by unauthorized persons. The control circuit used in the systems is based on the latest technology
• A fully synchronous digital timer of 0-9 cycles ON-OFF to feed exact pulse to the heat control card
• The Current of the Transformer should be adjustable from 5% to 100 % by thyristor switch
