Trustworthiness is the foundation of any successful supplier-customer relationship. A trustworthy supplier is transparent about their products' origin, quality standards, and supply chain processes. They should provide certifications and documentation to affirm that their electrodes comply with international standards, such as DIN, AWS, or ISO. Furthermore, a reliable supplier will support their clients with after-sales services, including technical support and return policies.
