of around 30 per cent. The new safe coat
impeders are available for all sizes as well
as for through flow or return flow systems.
Blissenbach is also able to offer an entire
return flow system without any cooling
inside the tube. In addition, recirculation
inside the ID-scarfer mandrel itself makes
sure that the tool body does not overheat.

New Tough Access™ MIG
consumables for greater reach
Tregaskiss, USA, has introduced a new
range of consumables, branded Tough
Access™, to improve entry into difficult-to-
reach areas during MIG welding.
Featuring sleek profile nozzles, these
consumables allow access into weld joints
that are obscured by complex designs or
fixturing. The consumables have nozzle
options for both robotic and semi-automatic
MIG guns.
Tough Access nozzle options include ½″
bottleneck and 5/8″ straight-bore styles and
feature an outside diameter of only 0.850″
to ensure successful welding in areas that
might otherwise be unreachable.
Both nozzle styles are compatible
with existing Tough Gun® goosenecks,
eliminating the need to order and stock new
gooseneck styles.
For optimal performance, Tregaskiss
recommends the use of standard-duty
consumables with its Tough Access
bottleneck style nozzles.

increases the lifetime of the impeder casing.
The objective being to make it resistant to
the molten particles that cannot be flushed
away – a problem that is not experienced
when using through flow impeders.
Improved impeder casing has been
achieved by applying a special coating
to the surface of the casing. Since the
introduction of this new product, users have

the new impeder ‘safe coat’ system. This
system ensures that the crucial part of the
impeder (the epoxy glass impeder casing),
is better protected against the heat and hot
spatter from the weld zone.
Due to the growing demand of return flow
impeder systems (which are mainly used
for small tubes or high carbon materials),
it was important to look into a solution that
