INSPECTION, MAINTENANCE, AND CLEANING

WARNING!

Before performing any maintenance on the Welder, unplug the

Power Cord (1A) from its electrical outlet and allow all components of

the Welder to completely cool.

1.Periodically open the Door (14A) from the unit and, using compressed air, blow out all dust and debris from the interior.

2.Always store the Welder in a clean, dry, safe location out of reach of children and other unauthorized people.

3.For optimal MIG weld quality, clean and inspect the Contact Tip (2E) and Nozzle

(1E) before each use, as follows:

Nozzle Inspection, Cleaning, and Replacement (MIG Only)

1.Turn the Nozzle (1E) counterclockwise while pulling to remove.

2.Scrub the interior of the Nozzle (1E) clean with a wire brush.

3.Examine the end of the Nozzle (1E). 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.

4.Reinstall the Nozzle (1E) after inspecting and cleaning the Contact Tip (2E).

ContactTip Inspection, Cleaning, and Replacement (MIG Only)

1.Make sure the entire Welding Gun (20A) is completely cool before proceeding.

2.Remove the Nozzle (1E) as explained above. Then remove the Contact Tip (2E).

3.Scrub the exterior of the Contact Tip (2E) clean with a wire brush. Check that the Contact Tip is the proper type for the wire size used.

4.Examine the hole at the end of the Contact Tip (2E) for the following problems: Shape: The hole should be an even circle, and should not be oblong or have any bulges in it.

Size: The Contact Tip will decrease in efficiency as the center hole enlarges. A Contact Tip that measures 150% or more the original size* should be replaced.

(*.045” or more for .030”Tips; .067” or more for .045”Tips.)

5.If any problems are noted with a Contact Tip (2E), have it replaced.

6.When inspection and maintenance is completed, reinstall the Contact Tip (2E) and Nozzle (1E).
