1.6 Resistance Welding
1.6.1 Molten and Sharp Metal Hazards
Resistance welders must wear clear goggles, lightly shaded welding goggles, or a full plastic face shield to protect their eyes from flying sparks. The welder should also wear leather or cut-proof gloves when handling sheet metal, because of its sharp edges. Comfortable clothing may be worn, but all collars and pockets should be buttoned, and shirt cuffs and pants cuffs rolled down to prevent sparks from entering these areas. A cap is recommended to protect the hair from sparks or hot metal. To prevent accidental burns, matches, lighters, and combustibles should not be carried in the pockets of work clothes.

1.6.2 Electrical and Mechanical Hazards
A resistance welding operator should never work on a damp or wet floor. If the floor is damp, the welding operator should work on a platform of wood or other insulated flooring material.
The welding operator should not open control panels of resistance welding machines because of the hazards of high voltages within the control cabinets.
The operator also must be careful to avoid being pinched when the electrodes of the resistance welding machine closes. These electrodes are brought together with considerable pressure by hydraulic or pneumatic (air) force.
Operating and safety instructions should be given to all operators regarding the hazards and operating sequences of resistance welding machines. They should be taught where to place their hands during machine operation.
