Welding Tips:
•
Always weld clean, dry and well-prepared material.
•
Hold gun at a 45° angle to the workpiece with nozzle about 1/2" from the surface.
•
Move the gun smoothly and steadily as you weld.
•
Avoid welding in very drafty areas. A weak, pitted and porous weld will result due to drafts blowing away the
protective welding gas.
•
Keep wire and liner clean. Do not use rusty wire.
•
Sharp bends or kinks in the welding cable should be avoided.
