Some welding applications require the flexibility and versatility of a hand held welding attachment. Hand held attachments allow welding of complex geometries that would require expensive fixturing when using conventional weld heads.
Hand held attachments provide a way for laboratories and businesses to lower their overall weld system costs. In general, welding attachments are easy to use, require low maintenance, and provide a great deal of flexibility for small production runs or research environments.
Hand held weld attachments provide users with the ideal welding solution for their specific application and needs. Available hand pieces include
single probe hand pieces, dual probe hand pieces, tweezer style hand pieces, pressure actuated single probe hand pieces, and pressure actuated tweezer-style attachments. Technical data and specifications for each weld attachment are found in this document.
