•Place the machine on a hard, flat surface where it will not fall or fall over. The maximum
permissible slope for transport and installation is 10 °.
•For better performance, place the machine at least 30 cm away from objects around it. Pay
attention to the overheating, dust and moisture around the machine. Do not operate the
machine in direct sunlight. If the ambient temperature exceeds 40 ° C, operate the machine at
lower capacities.
•Avoid running the machine with windy and rainy outdoor conditions. If it is necessary to operate
the machine in such cases, protect the working environment and the machine with a cover.
•Ensure that the operator can easily access the control and connections of the machine.
• Do not use an input fuse with a value greater than that specified on the product label.
2.2. DUTY CYCLE AND OVER-USAGE
• The operating cycle rate as defined in EN 60974-1 includes a time period of 10 minutes. For
example, if the machine is to be operated at 250 A in 60% of 250 A, the machine can weld
without stopping in the first 6 minutes of the 10 minute time period (zone 1). However, for the
next 4 minutes, the machine must be kept idle for cooling (zone 2).

12 AC Arc Weldin Machine User Manual
In the Electronic 250, overheating is carried out by welding 3-4 3.25 mm rutile electrodes
continuously. In this case, the overheat indicator on the front panel of the machine will be lit. After 5-
6 minutes the machine will cool down and the indicator will go off. Then it will return to working
condition.
Other models do not have a similar thermal protection system. When the machine is used within the
operating cycle specified above and indicated on the sign plate, cooling with the fan will prevent the
machine from overheat.

• For your safety, never use the machine without a plug on the end of the
mains cable.
• For the Electronic 250 and Turbo 250 models, check that the mains voltage is
220 V before connecting the machine to the mains. If the input cable is
connected to 2 phases, the machine will be subjected to 380 V voltage. This
type of user error causes the warranty of the machine to be avoided.
• Make sure that the mains supply to the machine is grounded.
• At the end of the factory, there is a CEE 7/4 plug with 1 Phase + 1 Neutral + Earth Line at the end of
the machine's power cord.
• If the plug of the machine is damaged and becomes unusable, it may need to be replaced.
Disconnect the machine from the mains before replacing the plug. Replace the plug with a new plug
of the same type (CEE 7/4). When doing this change, do not leave the yellow earth ground blank and
connect the ground line to the new plug ground point.
• Turbo 400 and Turbo 500 models are produced with three phase plug. Since these models operate
with 2 phase 380 V mains voltage, only 2 phase connections are connected to the plug. Do not
modify the plug.
• You will see the ground screw on the rear panel of the Turbo 400 and Turbo 500 models. Ground
the ground by using a diameter and length of cable that conforms to the grounding regulations.
