Castolin-Eutectic POWERMAX VRD



Introducing the safe welder of choice for many leading Australian mine sites – the Eutectic POWERMAX VRD Mine-Spec.The Eutectic POWERMAX VRD Mine-Spec (Voltage Reduction Device) has been designed in direct response to ‘world’s best practice’ Australian mining sector’s OH&S safety demands – and then some.

Take the safety critical aspect of Open Circuit Voltage (OCV). Australian standards demanded a maximum of 35V OCV at the electrode when a MMA VRD machine is not welding. The Eutectic POWERMAX VRD Mine-Spec is 12V – three times lower than the standard.When the welding circuit resistance is greater than 200 ohms (for example when touching the human body) the OCV is limited to 12V and the VRD must be active within 0.3 seconds after welding stops.

The software that controls the machine is designed to put the machine in fault mode if the VRD is not working, hence the POWERMAX VRD Mine-Spec machine is deemed to be ‘Fail to Safe’.Unlike other VRD alternatives, there is no need to continually hold down buttons when you are welding which causes operator fatigue.The braided heavy duty input power cable gives extra strength and protection.

An earthed braided cable is recommended for all applications where OH&S ‘DUTY OF CARE’ is essential.
