Some welding applications don't fit well in a weld head, or require more flexibility. Hand held welding attachments allow welding of complex geometries. Also hand held attachments are less expensive than weld heads. Welding attachments are easy to use, require low maintenance, and provide a lot of flexibility for small production runs or laboratory applications. Review the information below for technical data and images of the various hand pieces available.
