Castolin EuTronic Arc Spray 4 HF


Share this product


For anti-wear and anti-corrosion cold arc sprayed coatings 


The EAS4 HF was developed to improve running costs, coating deposition and ease of maintenance. The Gun design has been upgraded with screw in tips for

ease replacement and redesigned air concentrator together with front wire guide give significant efficiency gains.The Arc Gun and the drive system are coupled to a 350 amp,

switched voltage power source. This power source features sealed electronics for excellent reliability in the harshest of spray environments. The wire feeder unit is neatly

mounted on the power source, leaving it free to swivel and follow the operator whilst spraying. There is no motor in the gun. Instead, the Gun 4 uses a patented

‘Synchrodrive’ system, where a single, sealed motor with a fl exible drive arrangement, powers a reliable, positive drive push / pull up to a distance of 20 m. Graduated /quantifiable tensioner for the wire.


Technical data

Continuous operation at 350 amps for high productivity

Reliable Push Pull system for spraying up to 20 m in all positions

Allow complete use of all the wire, unlike push only system

New air cooled contact tubes with wear resistant tips

Double grooved feed rollers for double operation life

Robotic interface

EuTronic Arc is the highest productivity thermal spraying process. EuTronic Arc is an Arc Spray Process using a pair of wires which are melted by an electric arc. This molten material is atomised by compressed gas and propelled towards the workpiece to form a coating. EuTronic Arc is a cold spray process having the advantage of not

requiring the use of oxygen, kerosene or a combustible gas which means more economic coatings. Low running costs, high spray rates and effi ciency make it a good tool

for spraying extensive areas or a large number of parts.
