FALLING UNIT CAN CAUSE INJURY
Wrong positioned power source or other equipment may cause serious injury to persons or damage
to objects.
While repositioning the power source always carry by using the lifting eye. Never pull cable, hose or torch.
Always carry the gas cylinders separately
Before carrying the welding and cutting equipment, disassemble all the connections between and
separately carry the small ones by handgrips and the big ones by lifting eyes or by using appropriate
vehicles like forklifts
Install your machine on flat platforms having maximum 10
that it does not fall over. Install it on well
ventilated, non-confined places away from the dust, also avoiding the risk of falling caused by cables and
hoses. For gas cylinders not to fall over, attach it to the mobile machine or to the wall with a chain
Ensure that operators easily reach the controls and connections on the machine.

SAFETY RULES
OVERUSE CAN CAUSE OVERHEATING
Allow cooling period; follow rated duty cycle
Reduce current or reduce duty cycle before starting to weld again
Do not block airflow t

ARC WELDING CAN CAUSE INTERFERENCE
Electromagnetic energy arising during welding and cutting operations can interfere with sensitive electronic
equipment such as microprocessors, computers, and computer-driven equipment such as robots
Be sure all equipment in the welding area is electromagnetically compatible
To reduce possible interference, keep weld cables as short as possible, close together, and down low, such
as on the floor
To avoid possible EMC damages, locate welding operation as far as possible (100 meters) from any
sensitive electronic equipment
Be sure this welding machine is installed and grounded according to this manual
If interference still occurs, the user must take extra measures such as moving the welding machine, using
shielded cables, using line filters, or shielding the work area

Do not expose the welding machine to rain, protect from water drops and vapour.
PROTECTION
ENERGY EFFICIENCY
Choose appropriate welding method and welding machine for your work.
Choose appropriate welding current and welding voltage for the material and its thickness.
If you will have a long break after welding, turn off the machine after cooler fan cooled the machine.
