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.

INCORRECT

CORRECT

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.
