Safety Rules
“
Danger
”
indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury.
“
Warning
!
”
indicates a possible hazardous situation which, if not avoided, could result in death or
serious injury. The possible hazards are explained in the text.
“
Caution
”
indicates a possible hazardous situation which, if not avoided, may result in slight or
moderate injury.
“
Note!
”
indicates a situation which implies a risk of impaired welding result and damage to the
equipment.
“Important!”
indicates practical tips and other useful special-message. It is no signal word for a
harmful or dangerous situation.
Utilization for intended purpose only
•
The machine may only be used for jobs as defined by the “Intended purpose”.
•
Utilization for any other purpose, or in any other manner, shall be deemed to be “not in accordance
with the intended purpose”. The manufacturer shall not be liable for any damage resulting from such
improper use.
Safety signs
•
All the safety instructions and danger warnings on the machine must be kept in legible condition, not
removed, not be covered, pasted or painted cover.
Safety inspection
•
The owner/operator is obliged to perform safety inspection at regular intervals.
•
The manufacturer also recommends every 3-6 months for regular maintenance of power sources.
Electric shock can kill
•
Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit
is electrically live whenever the output is on. The input power circuit and machine internal circuits are
also live when power is on. In MIG/MAG welding, the wire, drive rollers, wire feed housing and all
metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded
equipment is a hazard.
•
Do not touch live electrical parts of the welding circuit, electrodes and wires with your bare skin or wet
clothing.
•
The operator must wear dry hole-free insulating welding gloves and body protection while performs
the welding.
•
Insulate yourself from work and ground using dry insulating protection which is large enough to
prevent you full area of physical contact with the work or ground.
•
Connect the primary input cable according to rules. Disconnect input power or stop machine before
installing or maintenance.
•
If welding must be performed under electrically hazardous conditions as follow: in damp locations or
wearing wet clothing; on metal structures such as floors, gratings, or scaffolds; when in cramped
positions such as sitting, kneeling, or lying; or in occasion when there is a high risk of unavoidable or
accidental contact with the work piece or ground. Must use additional safety precautions:
semiautomatic DC constant voltage (wire) welder, DC manual (Stick) welder and AC welder with
reduced open-load voltage.
•
Maintain the electrode holder, ground clamp, welding cable and welding machine in good, safe
operating condition. Replace damaged part immediately.
Electric and magnetic fields (EMF) may be dangerous
•
If electromagnetic interference is found to be occurring, the operator is obliged to examine any
possible electromagnetic problems that may occur on equipment as follow:
-
mains, signal and data-transmission leads
-
IT and telecoms equipment
-
measurement and calibration devices
-
Wearers of pacemakers
•
Measures for minimizing or preventing EMC problems:
-
Mains supply
If electromagnetic interference still occurs, despite the fact that the mains connection in accordance
with the regulations, take additional measures
-
Welding cables
Keep these as short as possible
Connect the work cable to the work piece as close as possible to the area being welded.
Lay term well away from other cables.
Do not place your body between your electrode and work cables.
