If OCV is not present at the welder output terminals, contact your local Lincoln Electric Authorized Field Service Facility.
2. Check the welding cables, clamps and electrode holder for loose or broken connections.
1.Check continuity (zero ohms) of lead W1A (black) from output ter- minal to reactor (L1). See the Wiring Diagram.
2.Check continuity (zero ohms) of lead W2 (black) from output terminal to stator winding. See the Wiring Diagram.
3.Check continuity (zero ohms) of lead W1A (black) from reactor (L1) to stator winding. See the Wiring Diagram.
4.Check reactor (L1) for continuity of winding. See the Wiring Dia- gram.
5.Check the stator for continuity of winding. See the Wiring Dia- gram.
6.Make certain the reactor and/or stator are NOT grounded. Mini- mum acceptable resistance to ground is 500
