Arc welding can be dangerous.
Protect yourself and others from possible serious injury or death.
Do not let the children come.
People with pacemakers should consult their physician before welding.
Read and understand the following safety messages.
For more information about security, it is recommended:

||ELECTRIC AND MAGNETIC FIELDS (EMF) can be dangerous:
- The electric current flowing through any conductor causes electric and magnetic fields (EMF).
- Welding current creates EMF fields around welding cables and welding machines.
- EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before handling a welder.
- Exposure to EMF fields in welding may have other health effects which are unknown.
- All welders should use the following procedures to minimize exposure to EMF fields from the welding circuit:
- Pass the electrode wires and working together - Secure them with tape when possible.
- Never coil the electrode cable around the body.
- Do not place your body between the electrode wires and work. If the electrode cable is on the right side, the work cable should also be on the right side.
- Connect the work cable to the workpiece as close as possible to the area being welded.
- No work near power supply welder.
||ARC RAYS can burn.
- Use a shield with filter and cover plates to protect your eyes from sparks and rays of the arc when welding or open arc welding is observed. The glass filter and helmet must meet ANSI Z87.I.
- Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.
- Protect others that are near a suitable non-flammable screening and / or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.
||FUMES AND GASES can be hazardous.
- Welding may produce fumes and gases hazardous to health. Avoid breathing.
- During welding, keep your head out of the fumes. Use enough ventilation and / or exhaust at the arc to keep fumes and gases away from the breathing zone. When welding with electrodes which require special ventilation such as stainless or hard facing (see instructions on container or data sheet Material Safety MSDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and below Threshold Limit Values (TLV) using local exhaust or mechanical ventilation. In confined or in some circumstances, outdoors spaces, the use of a respirator may be required. It is also required to take additional precautions when welding on galvanized steel.
- Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritants.
- Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in confined areas, to make sure that fresh air is breathed.
- Read and understand the manufacturer's instructions for this equipment and the consumables to be used, including data sheet Material Safety Data Sheet (MSDS) and follow the safety rules of the employer, welding equipment distributor or manufacturer.
