EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND
SKIN. PROLONGED EXPOSURE TO A WELDING ARC CAN CAUSE BLINDNESS
AND BURNS. NEVER STRIKE AN ARC OR BEGIN WELDING UNLESS YOU ARE
ADEQUATELY PROTECTED. WEAR FLAMEPROOF WELDING GLOVES, HEAVY
LONG SLEEVED SHIRT, CUFFLESS PANTS; HIGH TOPPED SHOES AND A
WELDING HELMET.
Once you have prepped the work piece (cleaning, cutting to size, etc.) you can position it in a manner
that will produce a solid weld. Ensure the workpiece(s) are securely held in place either with magnets or
clamps. Do some practice before welding your workpiece.
For effective welding, the surfaces to be joined must be free of dirt, rust, scale, oil or paint. Welding
on metals not properly cleaned will cause a brittle and porous weld. If the base metal pieces to be
joined are thick or heavy, it may be necessary to bevel the edges with a metal grinder at the point of
contact. The angle of the bevel should be approximately 60 degrees.

WARNING:
To help prevent eye injuries when grinding, always wear goggles. The grinder
must also be inspected to verify that it is in good condition.
During welding, the work pieces will become hot and will tend to expand. The expansion may
cause the pieces to shift from the regular position. If possible, the work pieces should be clamped
into the position.
ARC RAYS CAN INJURE EYES AND BURN SKIN!
To reduce the risk of injury from arc
rays, never strike a welding arc until you and all bystanders in the welding area, have welding
helmets or a shield in place and are wearing the recommended protective clothing. DO NOT
CONTINUE unless you have read, understand and intend to follow the entire SAFETY
SUMMARY provided at the front of this manual.
