The Model 650 is designed to be attached to our 6021, 6071, 620 and 6001, plus any of the models in between. The Model 650 allows the operator to cut to length and strip the wire in one simple operation. The length of the wire to be cut is adjustable. Different gauge stripping blades can be interchanged quickly and easily. Model 654 is a modified version of Model 650, except that Model 654 only cuts the wire. Model 654 is generally used by operators who are using C. S. & W. and need only to cut the wire; it does not strip the wire.
