General

The Robacta and Robacta Twin
robot hose packs are available in
numerous versions, and are used
in automated series production.
They are particularly suitable for
welding steel and CrNi.
Connections with external or
internal water connections, as well
as a large number of torch neck
versions are available.

For hose pack lengths up to 6
metres (19 ft. 8.22 in.), the Robac­ta and Robacta Twin robot hose
packs represent a low-cost alterna­tive to the motorised Robacta Drive
or Robacta Drive Twin robot hose
packs.

Safety

WARNING! Work perfor-

med incorrectly can cause

serious injury and dama­ge. The activities described
must only be carried out by
trained and qualified personnel.
Pay particular attention to the
enclosed „Safety rules“ docu-

WARNING! An electric

shock can be fatal. Only
carry out the activities described
if

- the power source mains

switch is in the „O“ position,

- the power source is un-

plugged from the mains.

Safety

WARNING! An electric

shock can be fatal. There
is also a risk of injury from filler
wire emerging. Switch the power
source mains switch to the „O“
position before cleaning the
welding torch and checking its
components.

CAUTION! When a

welding torch becomes

extremely hot from use, it
represents a fire risk. The
welding torch must only be
cleaned and its components
checked when it is cool.

ZHEN

Safety

CAUTION! Danger of

scalding by hot coolant.
Never check the water connec­tions until they have cooled
down.

CAUTION! Risk of injury

from unsatisfactory
connections. All cables, leads
and hose packs must be proper­ly secured, undamaged, insula­ted and adequately dimensio­ned.

NOTE! Never operate a

water-cooled welding
torch without coolant. The manuf­acturer shall not be liable for any
damage resulting from such
improper use. In addition, all
warranty claims will be forfeited.

Controls and connec­tions

* „Feeder inching“ button

for feeding in the filler wire with
no accompanying flow of gas
or current. As long as the
feeder inching button is held
down, the filler wire is fed in.
The feeder inching speed
depends on the length of time
that the feeder inching button
is held down (Fig. 2).

** Collision box cable

for connecting the cable to the
BNC socket on the collision
box. If the welding torch
collides with an obstacle, the
collision box stops the feeding
movement of the robot and
also stops the welding pro­cess.

Fitting the clamp/ad­justing clip

Important! The Robacta Twin

comes with a clamp fitted as
standard.

The Robacta clamp and Robacta
adjusting clip are for fitting the
Robacta hose pack to the robot or
to the welding machine.

The adjusting clip supports TCP
correction on the robot. The Robac­ta adjusting clip can be adjusted in
such a way that the position of the
arc is maintained during a correcti­ve movement by the robot. The
robot therefore needs no additional
corrective movement in the x or y
direction.

Care, maintenance
and disposal

Regular preventive maintenance of
the welding torch is essential for
problem-free operation. The welding
torch is subjected to high tempera­tures and heavy soiling. The
welding torch therefore requires
more frequent maintenance than
other components in the welding
system.

Important! When removing wel­ding spatter, avoid scoring or
scratching the torch. Future
welding spatter may become firmly
lodged in score or scratch marks.

- Do NOT bend the torch neck
