Portable Cold Welding System

The MTM portable cold welding system is a standalone device for the joining of foil to lead or lead to foil during the winding of transformer coils.

This machine allows for the joining of similar and dissimilar materials (Cu to Cu, Al to Cu, and Al to Al).

Combined thickness of foil and lead can range from 2 mm to 14 mm. This device is ideal for start and finish leads.

The cold welding process is easily repeatable and does not require special skills as compared to conventional hot weld methods. Cold welding is clean, quick – requiring no cooling time, lending a potential significant improvement to coil winding times and overall productivity.

Contact MTM to discuss suitability to your application.

See Winding Machines for integrated cold weld solutions, which offer increased speeds and flexibility in working with tap leads.
