WELDWELL NEW ZEALAND proudly present their range of arc welding electrodes in this book. We have manufactured electrodes in New Zealand since 1967. There are constant changes in this field because technology never stands still and we have access to welding electrode research to back our activities in the market place. We provide technical people to service our clients throughout Australasia, in countries of the Pacific Basin and in South East Asia. Therefore if you require help or advice with your welding problems, please ask and we will gladly assist. Included in our factory facilities is our own laboratory for materials, quality control and equipment to enable quick evaluation of new developments. This enables us to provide you, the customer, with the top quality electrodes you need for each application. The Weldwell Electrode Factory operates to the Telarc accredited ISO 9001 Quality Assurance System.
