We offer precision gamut of spot welder (PEDAL) that is fabricated using finest quality raw material. Our electronic control system comprises of STERCO SOLID STATE CMOS INTEGRATED WELD TIMER having timing range 5-99-199 cycles, adjustable in step of one cycle by means of Thumb wheel switch along with heavy duty electromagnetic contactor for switching purpose. Tap changing switch in 8 steps from 50 to 100% for adjustment of welding current. A mechanism coupled switch provided in the machine which initiates the weld only after preset pressure is built up.
The Electrode SystemThe rocker arm mechanism coupled with foot pedal is specifically used to attain the electrode force. The force can be varied by adjusting the nut provided on the back-rod below the compression spring of rocker arm mechanism.
Cooling SystemArms, electrode holders, electrode etc are water cooled. Water cooled transformers can be availed at an extra cost.
For Fine ControlThyristor can be used to control heat current from 5 to 95% of the available current. Weld time is also adjustable from 1 to 99 cycles in step of one cycle each. A pair of thyristor can be used for switching purpose instead of electro magnetic contactor at an extra cost.
Features :
Rocker Arm Type Spot WeldersThe international standard machine is viable for mass production as it required less operational efforts. These machines are designed and developed to meet the demand of various metal fabrication shops.
AdvantagesBesides spot welding the machine can also be used for Electrobrazing, Cross wire welding and resistance heating.
Salient Design FeaturesThe machine is highly demanded for its rugged body and easy maintenance. A heavy machined bracket is provided on top of the frame for Rockering the upper arm holder. "T" stotted face plate allows both vertical and horizontal adjustment of lower arm. Special electrode holder clamping system provides an increased current carrying section. These are available for maintenance of electrical, electronic and mechanical components.
Welding TransformerWith special design technique adopted to offer, maximum efficiency of the transformer, confirming to latest IS/4804 part I. It is Air/Water cooled, sandwitch construction of coils having core of high grade electrical steel. Class 'F' vacuum impregnated transformer helps to withstand higher temperature.
