1 SAFETY
Users of ESAB welding equipment have the ultimate responsibility for ensuring that
anyone who works on or near the equipment observes all the relevant safety pre-
cautions. Safety precautions must meet the requirements that apply to this type of
welding equipment. The following recommendations should be observed in addition
to the standard regulations that apply to the workplace.
All work must be carried out by trained personnel well-acquainted with the oper-
ation of the welding equipment.
Incorrect operation of the equipment may lead to hazardous situations which can
result in injury to the operator and damage to the equipment.
1. Anyone who uses the welding equipment must be familiar with:
its operation
location of emergency stops
its function
relevant safety precautions

2. The operator must ensure that:
no unauthorised person is stationed within the working area of the
equipment when it is started up.
no-one is unprotected when the arc is struck
3. The workplace must:
be suitable for the purpose
be free from draughts
4. Personal safety equipment
Always wear recommended personal safety equipment, such as safety
