GENERAL DETAILS

Designed as a primary transistor-switched welding machine, the
welding rectifier TRANSTIG 1600 / 1700 (DC) represents a further
deve-lopment of the transistor controlled welding machine. It is
especially suitable for TIG-manual-, and MANUAL ELECTRODE
WELDING in the DC area. The machine's compact dimensions,
low weight and modest power requirements are important advan-
tages, 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 protected 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 SEQUENCE
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.

SETTING-UP INSTRUCTIONS

DEGREE OF PROTECTION: IP23
The machine is tested to IP23, meaning that it is protected against:
l
penetration by solid bodies greater than diam. 12 mm
l
spray up to an angle of 60° to the vertical
OPEN-AIR OPERATION
As indicated by its protection category IP23, the machine may be
set up and operated in the open air. However, the built-in electrical
parts must be protected from direct wetting (see protection cate-
gory IP23)
COOLING AIR AND DUST
Position the machine so that the cooling air can be drawn in freely
through the louvers, and then be expelled unhindered. The cool-
ing air passes through ventilating slits in the casing into the interior
of the machine, where it cools inactive components in the ven-
tilation channel before flowing out through the ventilation outlet.
The ventilation channel has an important protective function. The
following cooling cycle is automatically controlled by an electronic
thermostatic cut-out system. (Fig. 1)
Make sure that any metal dust caused by e. g. grinding work is not
sucked into the machine by the cooling fan.
STABILITY
The power source can be stood on a surface with an inclination of
up to 15°! At inclinations above 15° there is a risk of the power
source toppling over.

COMMISSIONING - GENERAL DETAILS

Warning! Electrical work like fitting or changing the power
plug, may only be carried out by a qualified electrician!
The Transtig 1600 / 1700 may be operated as standard on a mains
voltage of 230V (+/-15% tolerance range, see fig. 2).
195V
-15%
Fig. 2 Tolerance range of the mains voltage
Note! The high frequency used for contact-free ignition
with TIG welding, can interfere with the operation of
insufficiently shielded computer equipment, EDP cen-
tres and industrial robots, even causing complete sys-
tem breakdown. Also, TIG welding may interfere with
electronic telephone notworks and with radio and TV
reception.
Warning! On machines designed for use with a special
voltage, the technical data on the machine rating plate
will apply.
Warning! The mains plug used must correspond exactly
to the mains voltage and current rating of the welding
machine in question, as given in the technical data!
Warning! The fuse protection for the mains lead should
be suitable for the current consumption of the welding
machine!
Warning! Never use the welding machine for thawing
frozen pipes!
