CAUTION
ACTIV8™
RECOMMENDED
COURSE OF ACTION
1. Connect the work lead to the work in a
location free of dirt, rust and paint.
2. Turn ON the power source.
1. Verify the contactor coil connections.
2. Replace the contactor.
1. Verify the gas supply is ON and flow-
ing.
2. Route the gas hose so it avoids sharp
corners and make sure nothing is on
top of it. Repair or replace damaged
hoses.
3. Apply filtered shop at 80psi to the
solenoid to remove dirt.
4. Check that all connections are in good
condition.
5. Replace the solenoid.
6. Remove the shielding gas filter. Apply
filtered shop air at 80 psi to the outlet
(male thread side) of the shielding gas
filter. Replace the shielding gas filter if
needed.
1. Keep the gun cable as straight as pos-
sible. Avoid sharp corners or bends in
the cable.
2. Remove the gun from the wire feeder
and pull the jammed wire out of the
gun and cable.
3. Blow dirt out of the liner with low pres-
sure (40psi or less). Replace the liner
if worn.
4. Use only clean electrode. Use quality
electrode, like L-50 or L-56 from
Lincoln Electric.
5. Replace the contact tip.
6. Verify the proper parts are installed.
7. Adjust the tension arm per the
Instruction Manual. Most electrodes
feed well at a tension arm setting of "3".
8. Verify the spool of wire moves with
minimal effort.
9. Replace the drive rolls if worn or filled
with dirt.
