Technical Specifi cations
The MiniMicro™ weldhead was designed for precision welding of small
diameter tubes and fi ttings. The MiniMicro™ weldhead is capable of welding
1/8” to 1/2 inch OD tubes and associated fi ttings.
Electrical
The MiniMicro™ uses a 24VDC motor with TACH feedback. It is controlled
by an orbital power-supply motor-control circuit to turn the rotor at the precise
speed to create a near perfect weld.
