Thyristor Controlled Arc Welding Rectifiers

FEATURES :

Fully Electronically regulated transformer - rectifier system

and fully controlled thyristors rectifier ensures....

1. Excellent welding characteristics as compared to non

thyristorised welding machines.

2. Constant welding current, output shor t circuit

protection, under / over voltage protection, over load

protection & Single phasing.

2. TIG welding [Along with separate high frequency unit]

Specially design for MS, SS, Cast, Iron, Aluminum,

Electrode, TIG, Structures, Pipe Line s , Of f shor e s ,

Rolling mills, and all types of heavy as well as light

weddings.

3. Economical as compared to conventional welding

machines as it saves upto 30% in electric consumption.

4. PWST Rectifier designed for extra smooth arc, reduction of

spatter level and high efficiency makes no load losses and

input current very low.

6. Sturdy & proven construction to withstand extra-ordinary

welding environments with feedback systems throughout

the entire range for stability of the arc specially for 6010

cellulosic, 7018 & 6013 electrodes.

7. Three Phase Transformer with full-wave Silicon Rectifier

power source assures trouble free service for various

welding process.

Note :
1) In accordance with PWS continued improvement, designs and / or specifications subject to
change without prior notice.
2) We invite you to comment and welcome any suggestions you may have on areas of service
and quality you feel you would like to see improved.
