"DR60-Argon Series” is an industrial Argon gas regulator suitable for Argon welding. Based on our accumulated technology, we adopt the flow gauge system widely used in European countries for this DR60-Argon Series. As the flow gauge system keeps the flow rate very regularly and evenly, it is very easy to use rather than flow meter system. They are designed and manufactured taking into consideration of the highest safety for welding works and easy operation.
