In welding there are many sources of electrical hazard over and above those encountered in everyday life. These include the welding power plant, auxiliary welding equipment such as cables, wire feed units, welding torches and electrode holders plus other associated tools and equipment such as grinders and electrode ovens etc.
Serious injury can also result from contact with the welding circuit, and shocks from this source are probably the most frequently experienced by welders.
Increased hazard situations
If the welder is hot and perspiring, or if he or she is working in wet, damp, hot, humid or cramped conditions, the skin and clothing may become wet.
