DISPOSAL
Recycle a tool damaged beyond repair at the appropriate facility.
Contact your local municipality for a list of disposal facilities or by-laws for electronic devices,
batteries, oil or other toxic liquids.
TROUBLESHOOTING
Visit a Princess Auto Ltd. location for a solution if the tool does not function properly or parts
are missing. If unable to do so, have a qualified technician service the tool.

MIG WELDING

PROBLEM(S)
Excessive Spatter
Porosity - small
cavities or holes
resulting from gas
pockets in weld metal.
Wire stubbing during
welding
Lack of Fusion − failure
of weld metal to fuse
completely with base
metal or a proceeding
weld bead
Excessive Penetration
− weld metal melting
through base metal

GASLESS MIG WELDER PN105I
POSSIBLE CAUSE(S)
1. Voltage too high.
2. Wrong polarity set.
3. Stick out too long.
4. Contaminated base
metal.
5. Contaminated MIG wire.
6. Inadequate gas flow or
too much gas flow.
1. Wrong gas.
2. Inadequate gas flow or
too much gas flow.
3. Moisture on the base
metal.
4. Contaminated base
metal.
5. Contaminated MIG wire.
6. Gas nozzle clogged with
spatter, worn or out of
shape
7. Missing or damaged gas
diffuser.
1. Holding the torch too far
away.
2. Welding voltage set too
low.
1. Contaminated base
metal.
2. Not enough heat input.
3. Improper welding
technique.
Too much heat.
SUGGESTED SOLUTION(S)
1. Select a lower voltage setting.
2. Select the correct polarity for the wire being used -
see machine setup guide.
3. Bring the torch closer to the work.
4. Remove materials like paint, grease, oil and dirt,
including mill scale from base metal.
5. Use clean dry rust free wire. Do not lubricate the
wire with oil, grease etc.
6. Check the gas is connected, check hoses, gas valve
and torch are not restricted. Set the gas flow rate to
0.35 CFM (8-10 L/min). Check hoses and fittings for
holes, leaks etc. Protect the welding zone from wind
and drafts.
1. Check that the correct gas is being used.
2. Check the gas is connected, check hoses, gas valve
and torch are not restricted. Set the gas flow rate to
.35 CFM (8-10 L/min). Check hoses and fittings for
holes, leaks etc. Protect the welding zone from wind
and drafts.
3. Remove all moisture from base metal before
welding.
4. Remove materials like paint, grease, oil and dirt,
including mill scale from base metal.
5. Use clean dry rust free wire. Do not lubricate the
wire with oil, grease etc.
6. Clean or replace the gas nozzle.
7. Replace the gas diffuser.
1. Bring the torch closer to the work and maintain
stick out of 3/16 to 3/8 in.
2. Increase the voltage.
1. Remove materials like paint, grease, oil and dirt,
including mill scale from base metal.
2. Select a higher voltage range and /or adjust the wire
speed to suit.
3. Keep the arc at the leading edge of the weld pool.
Gun angle to work should be between 5 and 15°.
Direct the arc at the weld joint Adjust work angle or
widen groove to access bottom during welding.
Momentarily hold arc on side walls if using weaving
technique.
Select a lower voltage range .
