evidences show that EMF may have effects on health. However, the research on the effect of EMF
is still ongoing. Before any conclusion, we should minimize exposure to EMF as few as possible.
In order to minimize EMF, we should use the following procedures:
Route the electrode and work cables together – Secure them with tape when possible.
All cables should be put away and far from the operator.
Never coil the power cable around your body.
Make sure welding machine and power cable to be far away from the operator as far as
possible according to the actual circumstance.
Connect the work cable to the workpiece as close as possible to the area being welded.
The people with heart-pacemaker should be away from the welding area.
Noise can damage hearing.
Noise from some processes or equipment can damage hearing. You must protect your ears from
loud noise to prevent permanent loss of hearing.
To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs.
Protect others in the workplace.
Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.
Hot parts.
Items being welded generate and hold high heat and can cause severe burns. Do not touch hot
parts with bare hands. Allow a cooling period before working on the welding gun. Use insulated
welding gloves and clothing to handle hot parts and prevent burns.
