FAQ

What does the 726 Bench Fixture do?

It is the weld head of the MTI Percussion Welder system. It clamps and aligns your weld materials: the moveable wireholder carries one weldment and thrusts it into the stationary one during the weld.

How do I align the parts?

Z-axis adjustment positions the weldments vertically and Y-axis adjustment positions them horizontally. Both have a typical travel of +/-0.250 in (+/-6.35 mm) with a fine-thread micrometer adjustment.

Which welder does it work with?

The 858 Percussion Welder. It also retrofits 528 and 628 systems with an upgrade kit.

How is the weld triggered?

With a foot pedal or a hand switch, operator-selectable.

What can I clamp in it?

The stationary workpiece holder has an adjustable clamping system for wires, terminals, leads and small assemblies. Custom tooling for specific weld geometries is an optional accessory.

Can it be used in an automated line?

Yes. It is operated manually by default and can be integrated into automated production lines with optional tooling.
