I used a Hobart Handler 125EZ flux core welder for about seven years. It was an affordable wire feed welder for smaller things. Flux core wire really works better with DC welding current, but the Harbor Freight welder is AC output. Some buy an inexpensive Chinese bridge rectifier to convert the output current to DC, and it improves the performance. Still, the welder will not have all of the refinements a more expensive welder has to make a good stable arc.
Try different flux core wire. I like Hobart wire. It just performs better than others I tried.
A common fan like you use in your home to stay cool is an asset when welding with flux core so you can blow away all of the smoke it makes. That smoke makes it really difficult to see where you are welding. Place the fan as near to the weld seam as is practical.
Flux core is to be drug, not pushed, when welding. I now have a real MIG welder and I can pull or push the bead. Pushing puts more light on the open seam so I can see more easily and stay on the seam.
Prepare the joint well for good root penetration. Weld 1/8' stock from both sides. Anything larger than 1/8' should be ground to make a 'V' where the joint will be.
Remove slag before welding over a previous weld.
I like to tack the weld different places. Then weld toward a tack, dragging the gun rather than pushing it because it is flux core. 'If there is slag, you drag.' Light from the arc will reflect off of the nearby tack and make it much easier to see where you are welding.
Always pick up metal while wearing gloves or use a pliers or tong. You always forget metal may be hot, and you get burned. It is no fun.

Maintenance

TO PREVENT SERIOUS INJURY,

FIRE AND BURNS:

Unplug the Welder,

rest the Gun on a heat-proof,

electrically non-conductive surface,

and allow all parts of the Welder to cool thoroughly

before service.

1. Periodically remove the Right and Left

side panels, and using compressed air,

blow out all dust from the interior.

2. Store in a clean and dry location.

3.

For optimal weld quality, clean and

inspect the Contact Tip and Nozzle

before each use. See below.

Nozzle Inspection, Cleaning, and Replacement

1.

Make sure that the entire Gun is completely

cool and that the Power Cord is unplugged

from the electrical outlet before proceeding.

2. Turn the Nozzle counterclockwise

while pulling to remove.

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 affect the weld and should be replaced.

5. Reinstall the Nozzle after inspecting

and cleaning the Contact Tip.

Contact Tip Inspection, Cleaning and Replacement

1.

Make sure that the entire Gun is completely

cool and that the Power Cord is unplugged

from the electrical outlet before proceeding.

2. Remove the Nozzle as explained in the

previous subheading. Turn the Contact Tip

counterclockwise and slide it off the welding wire.

3. Scrub the exterior 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. The included 0.030'

Tip is for 0.030' wire. Install a 0.035' Tip for

use with 0.035' wire (both sold separately).

4. 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.

5. If any problems are noted, Contact Tip

replacement would be advisable. Make

sure to select a new Tip that is the correct

size for the welding wire used (0.030' Tip for

0.030' wire – 0.035' Tip for 0.035' wire).

6. Reinstall the Tip and securely

reinstall the Nozzle as well.
