"Weldtronix" Rectifier produce high quality industrial welds at significantly lower cost than Rectifier available in the market. it may be used for stick, carbon gouging and as power source to GTAW/TIG welding process.
Introduction to process
» MMAW also called shield metal arc welder i.e.SMAW

Rectifier

Is a process that uses a flux covered metal electrode to carry an electrical current Fig.1-a the current forms an arc across the gap between the tip of the electrode and the work. The electric arc creates sufficient heat to melt both the electrode 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 electrode burns or vaporize, as the arc moves away, the mixture of the molten electrode and the base metal solidifies and becomes 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 two different method first is straight polarity (DCSP) Fig .1-a i.e. electrode on-ve. Polarity, second is reverse polarity (DCSP) Fig.1-c i.e. electrode on+ve polarity
 
Rectifier
Typical Volt- Ampere characteristics of a 'Drooping Power Source.

Drooping or constant current type power sources Fig.1-b are convenentionally 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 variations in arc length and consequent slight change in arc voltage, which are unavoidable even in the case of a skilled welder.
