CPRA800S / 1200S+SAW Tractor LW
 
Heavy Duty SAW Power Sources
SAW process produces the highest quality welds at speeds higher than MMA or MIG process. Standard single wire SAW can deposit up to 5 kg/hr and automatic multi-wire technique can reach up to 100 kg/hr.
 
CPRA 800(S) / 1200(S) are reliable power sources offered with AWM (LW) tractor for single wire SAW applications.
