Welding Tips
A good way to test welding technique is to examine a weld’s appearance after it has cooled and the slag has been removed. Then, better welding can be learned by adjusting your weld technique
to remedy any problems found.

SAFETY
SETUP
Chipping
TO PREVENT SERIOUS INJURY:Hammer Continue to wear
goggles and protective wear when cleaning a weld.
Sparks or chips may fly when cleaning.
1. A weld from flux core wire will be covered by slag, use |

not to damage the weld or base material. | ||

2.Then, use the Wire Brush to further clean the weld or use an angle grinder (sold separately) to shape the weld.
BASIC WELDING
Strike Test
A test weld on a PIECE OF SCRAP can be tested by
using the following procedure.
WEAR ANSI GOGGLES DURING THIS PROCEDURE.
WARNING! This test WILL damage the weld it is performed on. This test is ONLY an indicator of weld technique and is not intended to test working welds.
1.After two scraps have been welded together 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
3.A GOOD WELD will deform but not break, as shown on top.
A POOR WELD will be brittle and snap at the weld, as shown on bottom.
