Maintenance
tO pREVEnt SERiOuS inJuRy, FiRE and BuRnS:
unplug the Welder, rest the Mig gun on a heat-proof, electrically non-conductive surface, and
allow all parts of the Welder to cool thoroughly before service.
1. BEFORE EacH uSE, inspect the general
condition of the Welder. Check for:
• loose hardware
• misalignment or binding of moving parts
• damaged cord / e lectrical wiring
• frayed or damaged cables
• cracked or broken parts
• any other condition that may
affect its safe operation.
nozzle and contact tip inspection and cleaning
1. Make sure that the entire Mig gun is completely
cool and that the power cord is unplugged
from the electrical outlet before proceeding.
2. Pull the Nozzle to remove it.
3. Scrub the interior of the Nozzle
clean with a wire brush.
4. Examine the end of the Nozzle. The end should be
flat and even. If the end is uneven, chipped, melted,
cracked, or otherwise damaged, the Nozzle will
adversely effect the weld and should be replaced.
5. Unscrew the Contact Tip counterclockwise
and slide it off the welding wire to remove.
6. Scrub the outside of the Tip clean with a wire brush.
Clean out the inside of the tip with a tip
cleaner (sold separately). Check that the Tip
is the proper type for the wire size used.
7. Examine the shape of the hole at the end of
the Contact Tip. It should be an even circle; it
should not be oblong or have any bulges in it.
8. If any problems are noted, replace the
Contact Tip. Select a new Tip of the
correct size for the welding wire used.
9. Reinstall the Tip and securely
reinstall the Nozzle as well.

Do you have a question about the MIG 170 and is the answer not in the manual?
Questions and answers
The wire is not feeding through the welder. The trigger on the handle works and the gas sounds normal when sqeezing the trigger. The wire is lined up correctly and there appears to appropriate tension on the wire. It doesn't appear that the motor is attempting to turn. All chords are plugged in correctly as well. The temperature in my shop is around 5 degrees. It has been sub zero for approximately one week where I live. Everything sounds and works as normal except the wire isn't feeding. One last thing. I can pull the wire through with players and the wheel will turn when I do this. I need some help and direction. Thank you
If the wire is not feeding through the Titanium MIG 170 welder despite the trigger working and the gas sounding normal, follow these steps to troubleshoot:
1. Check the Wire Liner – Turn off the welder and push the wire liner back into the gun to ensure it is properly seated.
2. Inspect the Wire Spool – If the spool is stationary, turn off and unplug the welder. Slightly tighten the feed tensioner clockwise and retry.
3. Test Drive Tension – Press and hold the trigger to feed the wire against a piece of wood from 2 to 3 inches away. If the wire stops instead of bending, unplug the welder and incrementally tighten the feed tensioner clockwise until the wire bends under feed pressure.
4. Ensure Proper Contact Tip – Use a contact tip that matches the welding wire size to prevent feeding issues.
Following these checks should resolve the wire feeding issue.
