PRODUCT DESCRIPTION

General Physical Description

The AutoDrive™ 4R220 wire feeders are powerful yet compact wire drives for robotic and hard automation applications.

The MAXTRAC 4 roll wire drive gives steady feeding of all wire sizes and types. The drive features split wire guides, tool-less drive roll changing, dual spring pressure arms and changeable gun bushings all mounted in a precision die cast aluminum frame. A right angle gear box efficiently transfers motor power for both high torque and high speed.

The AutoDrive™ 4R220 features a powerful motor with an efficient two stage gearbox. This feeder is best for feeding larger diameter wires, pulling wire through long conduits, and in applications requiring extra ruggedness. A door covers the wire drive, pro- tecting it from dust.

General Functional Description

A high resolution tachometer precision for wire feed- ing forwards and in reverse.
