DC TIG WELDING
(see FIGURE B.3)
The TIG (Tungsten lnert Gas) welding process is
based on the presence of an electric arc between a
non-consumable electrode (pure or alloyed tungsten
with an approximate melting temperature of 3370°C)
and the workpiece. An inert gas (typically argon)
atmosphere protects the weld pool.
To avoid inclusions of tungsten in the joint, the elec-
trode should not contact the workpiece. For this rea-
son the arc is started through a Hi. Freq. generator.
For situations requiring no Hi. Freq., Touch Start Tig
reduces the short-circuit current to keep tungsten
inclusions to the minimum.
To improve weld bead quality at the end of the weld it
is important to carefully control the downslope of cur-
rent and ensure proper gas coverage over the weld.

A.C.-Pulsed TIG
When AC welding, a pulsed current can be used, with
similar effects to those described in pulsed direct
current welding.
FIGURE B.8
D.C.-Pulsed TIG A.C.- PULSED TIG
(see Figure B-6)
The use of pulsed direct current allows better control
of the weld pool during certain operating conditions.
When compared with traditional TIG welding per-
formed at the same average current, pulsed welding
results in a smaller heat affected zone which results in
fewer deformations and reduced chance of cracking
and gas entrapment.
Increasing the frequency constricts the arc, increases
stability and improves weld quality.

MAINTENANCE
SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
� Have an electrician install and ser-
vice this equipment.
� Turn the input power off at the
fuse box, disconnect or unplug
supply lines and allow machine to
sit for five minutes minimum to
allow the power capacitors to dis-
charge before working inside this
equipment.
� Do not touch electrically hot parts.
----------------------------------------------------------------------
INPUT FILTER CAPACITOR
DISCHARGE PROCEDURE
WARNING
The machine has internal capacitors which are
charged to a high voltage during power-on condi-
tions. This voltage is dangerous and must be dis-
charged before the machine can be serviced.
Discharging is done automatically by the machine
each time the power is switched off. However, you
must allow the machine to sit for at least 5 min-
utes to allow time for the process to take place.
------------------------------------------------------------------------
ROUTINE MAINTENANCE
Prevent metal powder from accumulating near the
aeration fins and over them.
Carry out the following periodic controls on the power
source:
� Clean the power source inside by means of low-
pressure compressed air.
� Check the electric connections and all the connec-
tion cables.
� Always use gloves in compliance with the safety
standards.
