Jat Series Air Cooled Welding Transformers


Salient Features

JET-ARC transformers are backed by the latest international technology to give you optimum cost effectiveness some special feature :
  • Welding current regulation by modern moving core magnetic shunt design

  • Stepless, smooth and infinitely variable current regulation

  • Adjustment of welding current possible even while welding is in progress; this enables fine current control

  • Compact in size and light in weight

  • ‘Open-delta’ connected design enables transformation of 3-phase input into single phase output

  • Adequate open circuit voltage for all general purpose AC and AC/DC electrodes

  • Convenient and easily manoeuvrable from job to job
