1 SAFETY
1.1 Signal Explanation
The signals in this section is aimed at graphically depicting the areas associated with welding
operations where personal safety can be compromised.
1.2 Hazards Relating to Arc Welding
The following activities may only be executed by qualified operators or artisans:
Installation, debugging, maintenance and repairs.
Since DC power remains in the machine's electrolytic capacitors after shut off, examination of and
maintenance on the equipment must be done in accordance with paragraph 5
The following signs and explanations detail the most obvious bodily hazards related to welding
operations. Be sure to take note and remind other interested parties of its importance.
ELECTRIC SHOCK
Electric shock can be lethal.
Never touch electrical parts.
Ensure personal insulation by wearing sound gloves and clothes void of wear and holes.
The operator should be insulated from ground and workpiece using dry insulation of adequate size.
Special care should be devoted when operating in confined spaces, elevated positions and wet
conditions.
Always ensure that power to the machine is shut off before installation.
Always ensure that equipment is installed correctly and the workpiece is properly grounded in
accordance with the operating manual.
When the machine is switched on the electrode and workpiece are live and care should be taken not to
touch live areas with uninsulated hands. This also applies when semi-automatic and automatic wire-
welding machines are operated
