6.6 FIXATION WELDING
>>> THE FIXATION WELDING MENU CAN BE ACTIVATED FROM THE "SETTINGS" USER LEVEL.
After activation (see
also
point
5.5
/
Settings), the fixation
mode appears as a
separate user level,
which
can
be
accessed
by
pressing the rotary controller several times for 1 sec.
This mode is used for the fixation of two work piece
parts. See also Chapter 7.3.1.
For using the fixation mode the tack welding set is
required (optional accessory).
PLEASE NOTE: TACK WELDING IS PARTICULARLY WELL SUITED FOR METALS WITH LOW ELECTRICAL
CONDUCTIVITY, FOR EXAMPLE: TITANIUM AND STEEL.
6.6 RETENTION WELDING
>>> THE RETENTION WELDING MENU CAN BE ACTIVATED FROM THE "SETTINGS" USER LEVEL.
After activation (see
also
point
5.5
/
Settings), the retention
welding mode appears
as a separate user
level, which can be accessed by pressing the rotary
controller for one second.
This mode is used for the welding of CoCr or NiCr-alloy
retention pins using the relevant pin welding adapter (ø
1.2, 1.3, 1.5 or 2 mm). See also Chapter 7.3 and 7.4.2.
7. WELDING INSTRUCTIONS
NOTE!
PRIOR
TO
WELDING,
ALWAYS
CHECK
THE
FUNCTION OF THE EYE PROTECTION FILTER AS
DESCRIBED IN CHAPTER 5.5 "FILTER TEST". IF THE
EYE PROTECTION FILTER (SHUTTER) FAILS TO
SWITCH OVER FROM LIGHT TO DARK, THEN IT MUST
BE IMMEDIATELY EXCHANGED BY SPECIALIST
PERSONNEL.
7.1 WELDING INSTRUCTIONS
•
First connect a metallic blank section of the workpiece
with the contact clamp.
•
Lightly touch the area to be welded with the tip of the
electrode until welding begins. In doing so, it is
important to remain in the position where initial contact
is made until welding begins, i.e. neither to follow the
electrode with the workpiece if it retracts slightly in the
handpiece, nor to pull back.
The welding process starts automatically as soon as the electrode touches the workpiece:
•
Shielding gas flows around the welding area.
•
A signal tone (if activated in the settings) notifies of the
arc.
•
The welding protection filter is darkened
•
The arc is triggered with a slight delay and the
electrode partly withdraws into the handpiece.
•
The welding protection filter is lightened and the
electrode returns to the initial position.
•
The shielding gas supply stops or the welding process
is started again by touching the workpiece.
WORK ONLY WITH EXTREMELY LIGHT CONTACT AND WITHOUT ANY PRESSURE TO THE TIP OF THE
ELECTRODE!
The PUK D3 is equipped with a function to prevent the electrode becoming welded to the workpiece by incorrectly pressing
too hard. If a welding point has already been set and is pressed too hard to the workpiece when it comes into contact again,
the welding point is not triggered; instead, the eye protection system will be darkened periodically to indicate that the
electrode is pressing too hard against the workpiece. The electrode's contact to the workpiece must be stopped for a short
time and the welding process must be started again.
THE WELDING PROCESS CAN BE HALTED AT ANY TIME BY MEANS OF LIFTING THE ELECTRODE AWAY
FROM THE WORKPIECE.
