General Details
Basic system
principle
Designed as a primary transistor-switched welding machine, the welding rectifier
TRANSTIG 1600 / 1700 (DC) represents a further deve-lopment of the transistor cont-
rolled welding machine. It is especially suitable for TIG-manual-, and MANUAL ELEC-
TRODE WELDING in the DC area. The machine’s compact dimensions, low weight and
modest power requirements are important advantages, both in the production and repair
fields.UP/DOWN control (continuous welding-current regulation via torch trigger) is also
integrated as standard.
Construction Features such as its powder-coated sheet-steel housing, the way its controls are pro-
tected by a plastic frame, and its bayonet-latching current sockets all testify to the high
quality of its design. The shoulder strap makes the unit easy to move around, both within
the factory and e.g. out on building sites.
Functional se-
quence
The voltage from the mains power supply is rectified. A rapid transistor switching device
inverts this voltage using a frequency of 100 kHz. The welding transformer produces the
required working voltage, which is rectified and fed to the output sockets. An electronic
controller adjusts the power-source characteristic
to suit the pre-selected welding process.
