flow and fan but does not have
wire drive.
1. Possible bad drive motor.
2. Possible bad Control P.C.
Board.
1. Perform the Wire Drive Test.
2. If 3 - 30 vdc is not at the drive
motor check for OCV at the
board on pins 1 and 10 on J3.
If OCV is present possible
faulty Control P.C Board.
Replace. If OCV is not
present check continuity of
wires CAP- and CAP+.
No wire feed when gun trigger is
pulled. Fan runs, gas flows and
machine has correct open circuit
voltage. ( 33 vdc maximum) -
weld output.
1. If the wire drive motor is
running, make sure that the
correct drive roll and wire
guide is installed in the
machine.
2. Check for clogged cable liner
or contact tip.
3. Check for proper size cable
liner and contact tip.
1. Perform the Wire Drive Test.
2. If wire drive test is OK, then
check for OCV at CAP- and
CAP+ on the control board. If
correct voltage is present,
possible faulty Control P.C.
Board. Replace.
