Welding Rectifiers are used as integral parts of TIG and metal arc welding jobs. These systems are suitable for TIG and arc welding jobs. The operator can set welding current of these systems for repeated times to maintain arc stability and also to regulate internal heat generation process. These systems have constant penetration performance for effective welding of metallic parts. Offered Welding Rectifiers are equipped with in built Anti stick to avoid freezing of electrode and hot start mechanism to speed up starting of these machines. As part of safety features, these systems are thermal run away protection function.
