•
Do not switch the function modes while the machine is operating.
Switching of the function modes during welding can damage the machine.
Damage caused in this manner will not be covered under warranty.
•
Disconnect the electrode-holder cable from the machine before switching on the
machine, to avoid arcing should the electrode be in contact with the work piece.
•
A safety switch is necessary to prevent the equipment from electric leakage.
•
Welding tools and accessories should be of high quality and in good working order.
•
Operators should be trained and or qualified. Electric shock: It can kill.
•
Connect the primary input cable according to Australian standard regulation.
•
Avoid all contact with live electrical parts of the welding circuit, electrodes and wires with
bare hands. The operator must wear dry welding gloves while he/she performs the
welding task.
•
The operator should keep the work piece insulated from
himself/herself. Smoke and gas generated whilst welding
or cutting can be harmful to people’s health.
•
Avoid breathing the smoke and gas generated whilst
welding or cutting. Keep the working area well ventilated.
•
Arc rays are harmful to people’s eyes and skin. Always
wear a welding helmet and suitable protective
clothing including welding gloves whilst the welding
operation is performed.
•
Measures should be taken to protect people in or near
the surrounding working area, from all hazards
associated with welding.
Fire hazard
•
The welding sparks may cause fire, therfore remove
flammable material away from the working area.
•
Have a fire extinguisher nearby, and have a trained
person ready to use it.
Noise: possibly harmful to people’s hearing.
•
Noise is generated while welding/cutting, wear approved
hearing protection when noise levels are high.
Machine fault:
•
Consult this instruction manual.
•
Contact your local dealer or supplier for further advice.
SAFETY
Welding and cutting equipment can be dangerous to both the operator and people in or near the
surrounding working area, if the equipment is not correctly operated. Equipment must only be
used under the strict and comprehensive observance of all relevant safety regulations. Please
read and understand this instruction manual carefully before the installation and use/operation
of this equipment.
*** CAUTION ***
Do not heat, cut or weld tanks, drums or containers
until the proper steps have been taken to insure that
such procedures will not cause flammable or toxic
vapours from substance inside. These can cause
an explosion even though the vessel has been
“cleaned”.Vent hollow castings or containers before
heating, cutting or welding. They may explode.
