Possible Causes and Solutions

1.Stickout too long: Reduce stickout.

2.Dirty workpiece or welding wire: Make certain that workpiece and wire are both clean and free from oil, coatings, and other residues.

STRIKE TEST

A test weld on a piece of scrap can be tested

by using the following procedure.

WEAR ANSI GOGGLES DURINGTHIS PROCEDURE.

1.After two scraps have been welded to- gether and the weld has cooled, clamp one scrap* in a sturdy vise.

2.Stay clear from underneath while you strike the opposite scrap with a heavy hammer, preferably a dead-blow hammer.

3.A good weld will deform but not break.

A poor weld will be brittle and snap at the weld.

*This test will damage the weld it is performed on. This test is only an indicator of weld tech- nique and is not intended to test working welds.

Possible Causes and Solutions

1.Wire feeding too fast: Reduce wire feed speed.

2.Stickout too long: Reduce stickout.

3.Dirty workpiece or welding wire: Make certain that workpiece and wire are both clean and free from oil, coatings, and other residues.

10.When the weld is complete, lift the electrode wire clearly away from any grounded object, set the Face Shield down, turn toward the Flux Wire Welder, and turn the Power Switch to the OFF position.

11.Unplug the Power Cord from the electrical outlet. Be sure to set the torch down on a nonflammable, nonconductive surface.

12.The Wire Brush/Hammer (39) can now be used to clean up the weld.

CAUTION: The weld may still be quite hot and sparks/chips may fly when cleaning. Be certain to continue to wear ANSI approved safety goggles and protective wear when cleaning a weld.

The Hammer can be used to knock off any excess spatter and to help knock down any ridges. Be careful not to damage the weld or material when striking it.

The Wire Brush can then be used to help remove oxidation and some fine spatter.
