Maintenance
Warning: Before performing any maintenance on the Welder, unplug the Power Cord from the electrical outlet and allow all parts of the welder to cool thoroughly.
1.Periodically remove the Right and Left side panels (12 and 13), 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 (2b) and Nozzle (3) before each use, as follows:
Nozzle Inspection, Cleaning, and Replacement
A.Make sure that the entire Torch (parts 1a through 3) is completely cool and that the Power Cord is unplugged from the electrical outlet before proceeding.
B.Turn the Nozzle (3) counterclockwise while pulling to remove.
C.Scrub the interior of the Nozzle clean with a wire brush.
D.Examine the end of the Nozzle (3). 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.
E.Reinstall the Nozzle (3) after inspecting and cleaning the Contact Tip (2b).
Contact Tip Inspection, Cleaning, and Replacement
A.Make sure that the entire Torch (parts 1a through 3) is completely cool and that the Power Cord is unplugged from the electrical outlet before proceeding.
B.Remove the Nozzle as explained above. Using the third oval hole on the provided Wrench (43), turn the Contact Tip (2b) counterclockwise and slide it off the welding wire.
C.Scrub the exterior of the Tip clean with a wire brush. Check that the Tip is the proper type for the wire size used (0.9 mm for .030” wire).
D.Examine the hole at the end of the Contact Tip (3) for the following problems:
Shape: The hole should be an even circle, it should not be oblong or have any bulges in it.
Size: The Tip will decrease in efficiency as the center hole enlarges. A tip that
measures 150% or more the original size* should usually be replaced.
*13.5 mm or more for 0.9 mm Tips (2b)
If any problems are noted, Contact Tip (2b) replacement would be advisable. Make sure to select a new Tip that is the correct size (0.9 mm) for the welding wire used (.030”).
E. Reinstall the Tip (2b) and securely reinstall the Nozzle (3) as well.
