1. Important safety instructions
Scope of application of the dent removal system
Perform body repair work, such as dent removal, using resistance welding techniques and straightening
devices. Local heating of the metal sheets using the copper electrode.
The VAS 6321 A/13 inverter welder and the pulling and straightening tools may not be used for other
purposes!
No structural changes, even minor ones, are permitted; these will render the legal guarantee void!
CARBON GmbH accepts no liability for damages to persons, animals, property or the machine itself
resulting from improper application of the safety criteria specied in this usage information, even
through minor manipulations, or through the use of non-original or non-compatible spare parts.
Persons
The use of qualied personnel is recommended when carrying out work with the VAS 6321 A. Any
persons working with the system must in any case have been made aware of the possible risks and must
have read and understood this usage information.
Participation in the familiarization training is highly recommended!
Safety instructions
Read the instructions carefully. Failure to observe the safety regulations and basic precautions may result
in serious physical injury and damage to property. Make sure that employees working next to you are not
injured, for instance by sparks that may occur during the work process.
Protective clothing
Wear work clothes with long sleeves, gloves, safety shoes, headgear, safety glasses, and hearing protec-
tion if necessary. The equipment heats sheets of metal to high temperatures and can spray sparks. To
avoid burns and other possible injuries, the general safety regulations of welding equipment and body
repair must be observed when working with the CBR dent removal system!

Important: Explosion hazard!
Do not make repairs to sheet metal or containers that have contained inammable materials, such as a
fuel tank.
Avoid a potentially explosive environment.
To avoid any risk, do not use the device near inammable liquids, gases or other ammable and danger-
ous objects. The sparks generated when using the device can otherwise lead to explosions.
Important: Risk of burns and poisoning!
The sheet metal parts to be machined can be heated to very high temperatures. Toxic vapors or gases
may be generated, depending on the composition of the surface coating on both the front and the back of
the metal sheet, e.g. zinc, lacquers, sealing material, anti-drumming material, etc.
To avoid poisoning, it is essential to observe appropriate precautions such as good ventilation in the
workplace or the wearing of respirators in the event that there is insucient ventilation.
Always work attentively and concentrate!
Magnetic ields
Please note that the VAS 6321 A/13 PowerInverter included in the VAS 6321 A generates powerful
magnetic elds that exert powerful attractive forces on magnetic metals. Watches, magnetic cards and
data carriers can be damaged by this.
Wearers of pacemakers must always consult their physician before approaching the welding area!
Important: To avoid damage to the vehicle electronics, the vehicle’s electrical system must be
disconnected from the power source in accordance with the vehicle manufacturer’s specications
before using the VAS 6321 A/13!

8. PowerInverter | Power Source (VAS 6321 A/13)
8.1 The PowerInverter
The VAS 6321 A/13 PowerInverter is the multifunctional power source (hereinafter referred to as PS) at the heart of the
VAS 6321 A. It enables a wide range of applications in the repair of damage to the vehicle body.
There are 6 programs available to the user for dierent tasks, which are selected via pushbuttons (5-10). Our technicians
have established basic values for each of these programs, and these are stored in the control electronics of the PS and
automatically set after the program is selected.
The predened settings can be changed step by step and independently of each other with the buttons (11-14), or adapted
to the respective conditions (material quality, metal sheet thickness, etc.) – the adaptation is shown in the displays for time
(11/12), or power (13/14) respectively.

8.2 Operation of the PS
After switching on the PS with the main switch (1), the MANUAL (2) and GROUND (5) LEDs light up. This basic setting
ensures that no accidental short circuit can occur between the MultiTool and the ground clamp.
Programs 1 and 3 to 6 are operated in automatic mode, and in program 4 it is possible to select between continuous current
and pulsing three times.
Program 2 can be executed in automatic mode (welding process is triggered on contact with the bare surface), or in manual
mode (welding process is triggered at the press of a button on the MultiTool).
Note that use of the PS in Manual mode requires the optional MultiTool with button (part number C1-06).
If automatic mode is selected, the PS switches to standby mode after 5 minutes of inactivity. To reactivate the PS, one of
the programs must be selected.
For your consideration: By selecting the program indicated by the illuminated LED again, the previously adjusted values for
time or for power remain valid.
The pictures above show the simple operation of the pushbuttons on the PS for quick retrieval of the respective programs.

Important
Whenever working with the VAS 6321 A, make sure that the zinc coating is removed from the sheet metal without
leaving any residue. This should be done with nylon discs or similar at low speed in order to introduce as little heat as
possible into the sheet metal being machined.
8.3 Attaching the ground clamp with program 1
Important: To avoid damage to the vehicle electronics, the vehicle’s electrical system must be disconnected from the power
source in accordance with the vehicle manufacturer’s specications before using the VAS 6321 A/13!
To establish a ground connection to the vehicle, you must plug the ground clamp with connection cable into the ground
socket on the PS, switch on the PS at the main switch and select program 1.
After switching on the PS, select program “GROUND” and
press “AUTO” on the panel.
Important: To ensure the optimum safety conditions when
carrying out any work on the body panels, make sure that all
zinc coatings are removed without leaving any residue.
8.4 Welding on the ground clamp
Plug the MultiTool with connection cable into the Auto socket on the PS and insert the shrinking tool into the MultiTool. The
ground clamp can be welded onto a bare surface quickly and easily with the welding tip. To do this, place the ground clamp
on the sheet metal so that the lower ring (contact surface) lies at. Press on the bolt of the ground clamp with the shrinking
tool. As soon as the welding tip of the bolt touches the bare panel, the automatic welding process starts – if you are working
in manual mode, you must trigger this process by pushing a button. The welded joint can be released quickly and easily by
turning the knurled screw.
Important: With this type of ground connection, it must be ensured that the entire contact surface of the ground clamp lies
at on the bare surface of the panel in order to avoid loss of performance, high wear/damage to the ground clamp and
damage to the panel!
