Copper tip clamping fingers
Copper tipped, aluminum hold down fingers are standard on all Jetline Seam Welders, The copper tipped hold down fingers assist in the chilling the weld joint. Copper tooling absorbs and dissipates heat through the use of additional thermal mass, operating under pressure against the work piece.
Back-up insert
Inserts are quickly and easily interchanged into the Backup Mandrel to accommodate a variety of material types and thicknesses. Copper inserts dissipate heat generated during the welding process.

Additional inserts are available to cover a wide range of material types and thicknesses.

Inserts are available with or without gas back-up capabilities.
Back-up Mandrel
Designed to support the part being welded and hold the back-up inserts.

Droop mandrels are available to ease loading and unloading of parts.

Optional Water cooled mandrels are available.
