Arc Power Control

Process In CO2/MIG Welding or Gas Metal Arc Welding (GMAW) process, arc is formed between a continuously fed filler wire and work piece.The shielding is obtained by an externally supplied gas. CO2 is used as a shielding gas in the welding of mild steel and low alloy steels. Argon / Argon mixtures are used for shielding while welding stainless steel and non ferrous metals. Filler wire is in the form of spool. The equipment for GMA W consists of: A constant potential D. C. power source. Wire feeder with built in controls for feeding the filler wire. A welding gun / torch. Set of accessories comprising of welding cables, gas hose, regulator with flow meter, gas preheater and welding helmet, gloves etc. Advantages Of Process Higher welding speeds and deposition rates. Low heat input and very low or no slag formation. No frequent changing of electrodes. Easily adoptable for full automation with the help of suitable welding aids. No stub end loss. ARC POWER MIG / MAG welding machines are characterized by a high degree of reliability, quality, flexibility and competitive price. Application Automobile and Textile industry, Sugar and Chemical gas preheater and equipment and sheet metal fabrication etc.

Process In Tungston Inert Gas Welding (GTAW) process, the arc is formed between a non consumable electrode and the work piece. The arc is shielded by inert gas such as Argon or Helium to avoid oxidation. A filler metal may be used depending upon job requirements. The equipment for TIG consists of: A drooping potential DC Power source. HF Control unit Set of Accessories like Welding cables, Torch, Regulator, Flowmeter, Gas hose etc. Advantages of the process: Intense source of heat Welds are very clean and smooth. Hence cost of finishing reduced. Ideally suited for welding of thin gauges. Suitable for almost all metals. Application: Welding of Stainless steel, Carbon steels, Copper, Aluminium and its alloys. It is commonly used for Dairy equipments, Solar equipments, Heat exchangers, Steel furniture etc. ARC POWER make TIG units are availbale with or without power sources in the range of 200 A to 400 A either Gas cooled or Water cooled.

In Submerged Arc Welding a continuous solid wire, in the form of a spool is used as electrode. It is mechanically fed resulting in high deposition rates. The arc is submerged under a layer of dry granular flux. The higher feed enables the use of higher currents. This is one of the most economical processes for long joints and deep groove butt welds. The equipment for SUB ARC consists of A constant potential DC Power source. Welding head (Boom or carrige mounting type) Set of Accessories Advantages of the process Deep penetration X ray quality welds Uniform bead shape Faster rate of welding Higher deposition rates. Application Fabrication of penstock pipes, pressure vessels, LPG cylinders and other stuctural work.
