We are one of the distinguished organizations, known for offering premium quality industrial equipment that are extensively used in fabrication & repair works of nuclear plant, chemical process plants, refineries, steel plants, thermal power plants etc. Suitable for producing identical welds numerous times with required accuracy, our range is available at competitive rates. It includes :


TIG Welding Machines
TIG Welding Machines

We are providing TIG Welding Machines, diode based thyristorised and invertor based equipments in different models as per current capacity and application. Our models are mandatory equipment in any industrial and manufacturing infrastructure, installed to ensure quality and help optimize design. They are a part of capital equipment, which once installed, are not replaced for reasonable time period. We are offering submerged arc welding equipment that are suitable for tungsten inert gas welding commonly know as "Argon Arc Welding". This process in mainly used where high deposition is not an essential factor, but where emphasis is to be made on leak proof, clear finish strong joint structure of stainless steel, copper and their alloys. The process comprises of basis arc formed by actuating high frequency circuit. Operational process include :

  • Once the arc is formed, the high frequency is discontinued by provision of auto cut-off facility during stainless steel and copper welding applications and is made to superimpose continuously during welding of Aluminium and the alloys.
  • Filler metal uses minimum deposition requirements
  • Direct current, dropping characteristics power source is used in case of stainless steel and copper welding applications
  • A special device called D.C. suppressor unit is essential for avoiding direct current in filtration
  • The basic arc thus formed gives sufficient heat input to melt the parent metal depending upon the current range selected
  • In this process the argon gas is used for shielding the arc.

DC Welding Rectifiers
DC Welding Rectifiers

We are providing precision-engineered DC Welding Rectifiers diode based,thyristorised & invertor based. These machines are suitable due to their low power consumption, consistant welding current and better weld characteristics.



Industrial Rotator
Industrial Rotator

Empowered with sound industrial understanding and knowledge about the machines we are dealing in, we are able to fabricate and offer industrial rotator that are most suitable for achieving accurate results. Our premium quality rotators have high operational efficiency and wide industrial application.



Column & Boom
Column & Boom

Column & Boom Manipulators are designed to work independently or in conjunction with rotating and/or positioning equipment to locate an Automatic Welding Head in the correct position over the work-piece to achieve the necessary down hand weld. They can also be used in conjunction with Cutting Machine Installations, Semi-Automatic Welding Installations and for supporting Grinding Heads. Column & Booms allow the use of fully automated production techniques which increases quality, and reduces production time and operator fatigue.
