Welding Machine Grounding Safety

Grounding of electrical circuits is a safety practice that is documented in various codes and standards.

Welding machine grounding safety.

1926 351 c 1 a ground return cable shall have a safe current carrying capacity equal to or exceeding the specified maximum output capacity of the arc welding or cutting unit which it services. If the welding operation must be done on steel or other conductive material use an insulating mat under the operator. A typical arc welding setup may consist of several electrical circuits. Various codes and standards document grounding electrical circuits as a safety practice.

Standard 1910 254 d 3 requires grounding of welding machines frames to be checked and mandates special attention to the ground connections of portable machines. Wear proper protective equipment such as rubber boots and rubber pads if performing arc welding in wet or high humidity conditions. Standard 1910 254 c 2 i requires grounding of welding machines but exempts engine driven machines. In welding grounding is critical to arc welding safety.

A typical arc welding setup may consist of several electrical circuits. Applying and maintaining proper grounding methods within the welding area is important to promote electrical safety in the workplace. Consensus standard ansi z49 1 2012 safety in welding cutting and allied processes provides guidance in the safe setup and use of welding and cutting equipment and the safe performance of welding and cutting operations. Grounding means much more than punishing your teenager by restricting his privileges.

Paragraph 4 3 provides more direction on clothing selection for welding tasks. Grounding of electrical circuits is a safety practice that is documented in various codes and standards. Ground returns and machine grounding.
