Fan cooled transformer having core of high grade silicon steel.

Thyristor controlled electronic timer with electronic heat control, to give heavy duty high speed operation, providing smooth, stepless and accurate adjustment of welding current.

High quality roller bearings carrying the roller shafts, guaranteed longer-life of the roller heads.

Minimum wear of the electrode wheels due to efficient cooling system.

Study drive shafts ensure nonslip drive.

Leak proof joints at much lower costs, than conventional welding.

The main frame of the machine is of the heavy rigidly reinforced and robust welded steel constriction.
