Torch Service Centre
– Makes your robot welding
more effective and accurate
Robot welding stations are today a common and
well known tool in the industry. The continuous
development of robots, welding equipment and
work piece positioners has dramatically decreased
the cycle time and increased the uptime.
The worst load in a robot welding cell has
the welding torch. It is exposed for heat, welding
spatter and in worst case, collisions.Welding
torches are made for such environment but need
regulary cleaning, measuring and TCP-definition
in order to weld with good quality and accuracy.
It consists of two main units – a mechanical
torch cleaner and a tool center point definer
including a wire cutter.
Spatter – a production problem
It is impossible to avoid spatter during welding
operations. Hot particles from the arc easily adhere
into the gas nozzle.The problem is familiar to all

welders – a gradual build up of spatter in the
nozzle leading to blocked wire feed and absence
of shielding gas or short circuiting make the
torch useless.
Even relatively small amounts of spatter in
the gas nozzle affects the operation, giving poor
starting and low quality weld as a result. But what
is a nuisance to welders becomes a potentially
serious problem to welding robots.
The Torch Service Centre is an integrated
system for mechanically removing spatter from
welding torches.The robot control system
operates and supervises the cleaning operation
to make sure that it will not start until the torch
is clamped in the correct position.
This ensures that no vibration or shocks reach
the robot and the torch is locked in the same position every time for more precise cleaning and less
wear on the parts cleaned.The entire cleaning
operation is automatic in one sequence, including
mechanically cleaning, pneumatic cleaning and
finally oil injection into the gas nozzle.
