Ww manufacture AC Arc Welder with the model no. JAT-200. These machines are quieter, more energy efficient. This machine requires less maintainance. This machine can be classified by the method by which they control or adjust the welding current. The major classification are multiple coil called Taps.
We manufacture AC Arc Welder with the model no. JAT-450. This machine is a moving core type welding transformer. This machine can be used in variety of metals and position and it is versatile also.
MMAW (Manual Metal Arc Welder) also called shielded metal arc welder i.e. SMAW is a process that uses a flux covered metal electrode to carry an electrical current and arc across the gap between the tip of the electrodes and the work. The electric arc creates sufficient heat to melt both the electrodes and the work. Molten metals from the electrode travels across the arc to the molten pool of metal are surrounded, purified and protected by gaseous cloud and a covering of slag produced as the flux coating of the electrodes burns or vaporize. As the arc moves away, the mixtures of the molten electrode and the base metal solidfies and become one piece.
Most common method of joining metals.
High quality welds can be achieved rapidly and with excellent uniformity.
A variety of metal types and metal thickness can be joined with one machine.
DC Rectifier, Welding Transformer are used for this type of process.
DC welding is done on tow different method first is straight polarity (DCSP) Fig. 1-c i.e. Electrodes on -ve. Polarity, second is reverse polarity (DCRP) Fig. 1-d i.e. Electrodes on ve polarity.
Drooping or constant current type power sources are conventionally used for manual metal arc welding (MMAW) or gas tungsten arc welding (GTAW), the obvious reason being that with this type of characteristics, the welding current remains substantially constant irrespective of small variation in arc length and consequent slight change in are voltage, which are unavoidable even in the case of a skilled welder.
DC tungsten inert welder (Gas Tungsten Arc Welder) is a compact, portable TIG control unit which constitute a complete TIG Welding machine when connected to a stand. MMAW rectifier for ferrous metal (MS/SS), copper and non-ferrous (aluminum and its alloys) metal.
Features:
An electronical controlled unit which eliminates the use of costly and bulky HF and DC suppressor unit Incorporated with solenoid valve to economize the costlier argon gas.
Built-in feature of pre-flow control to prevent the electrode oxidization at the start of weld.
Electronically balancing the AC wave forms helps*,, in total removal of oxide films during welding of aluminium and its alloys.
Superior arc striking through a discharge of 101 of high frequency voltage pulse.
Auto HF cut-off in DC mode.
