1 General Information
Information about safety regulations, symbols, copyrights, protection rights,
usage location conditions and notes on resistance welding can be found in the
back section of these operating instructions.
Please read this information carefully before using these operating instructions.
These operating instructions should help you familiarize yourself with the system and
take advanta
g
e of its application possibilities when used as directed.
It contains important notes to help operate the unit safel
y
, properl
y
, and economicall
y
.
Observing the notes will help avoid risks, decrease repair costs and down times, and
enhance reliabilit
y
and the service life of the unit.
It is a rule: Safety first!
Warning
Incorrect or inappropriate configuration, installation, settings, handling or use can cause
mechanical, electrical or thermal hazards, which may result in serious damage or injury.
Ensure the correct execution of these points and follow the respective notes in the
operating instructions.
Danger
Do not put the system into operation before you have read the operating instructions!
Danger Persons with cardiac pacemakers and metallic implants are prohibited from
approaching to within a radius of at least 5 m of welding equipment!
Crushing Hazard
There is a risk of crushing during the adjustment movement due to closing electrodes,
stops for limiting adjustment or stroke movement and the stop on the basic pincers unit
for limiting floating movement.
Warning
This Class A welding equipment is not supposed to be used in living quarters, where
the power supply is carried out by a public low voltage supply.
There it can be difficult to ensure electromagnetic compatibility because of conducted or
radiated disturbances.

2.3 Structure of Weld Heads and Weld Pincers
Servomotor driven weld heads normally consist of:
 a guide head,
 a servo module
 connections for secondary cables
 a stand (if it’s a stand type)
 electrode holders
 electrode quick changer
 a pair of electrodes
The stand type with lower stroke cylinder contains the stroke cylinder, which adjusts
the backing electrode.
Servomotor driven weld pincers additionally consist of:
 a basic pincer unit for vertical or horizontal installation. The mounting of the weld
head (active side) and of the passive side on the slide of the basic pincer unit allows
the compensation of product tolerances.
 a lockin
g
unit. It secures a defined pincer position

The power switch turns on only the MNC and the operating panel,
not the complete AWS3 system!
Via the settings on the MNC a servomotor is actuated. The servomotor is located in the
servo module of the motor head MFPxxx. It powers a low-friction spindle, which is used
for the transformation of the electrode motion. During this the speed of high-lift and
return stroke of the electrodes and the distance covered are digitally specified, monitored
and displa
y
ed.
Torque can be utilized to accurately specify the welding pressure. This is specified by
the servomotor control electronics..
The separate layout of the signal line for the resolver, and the line for the power control
and motor head initiator, ensures the signal flow. This enables reproducible welding
