PERFORMANCE
• 2-roll wire drive system for easy wire feeding.
• The LN-25 provides constant wire feed speed for use with
constant voltage (CV) power sources, and arc sensing wire
feed speed for use with constant current (CC) power sources
(1)
.
• Dynamic braking system stops wire feed motor quickly to
minimize crater sticking problems.
(1) Most semiautomatic wire welding processes perform better using CV power sources.
Be sure the proper power source is used for your application. Contactor life may be
shortened in applications using CC power sources with high OCV.
