Impeder protection from weld zone heat and spatter

Blissenbach, Germany, manufactures 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

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 reported reduced downtime by an average

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.

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. Email : info@blissenbach.de Website : www.blissenbach.de
