The approximate indication of the average current
used for welding with ordinary steel electrodes is gi-
ven by the following formula:
I = 50 x (Øe – 1)
where: I = the intensity of the welding current e = the
diameter of the electrode
Example for an electrode with a diameter of 4 mm:
I = 50 x (4 - 1) = 50 x 3 = 150 A

Warning about possible problems and their
remedy
The extension cord and welding cables are considered
the most common cause of the problem.
If you have
any problems, follow these steps:
• Check the value of the supplied mains voltage.
• Make sure that the power cord is fully connected to
the power outlet and the main power switch.
• Make sure the fuses or the circuit breakers are OK.
If you are using the extension cable, check its length,
cross-section and connection.
Make sure the following parts are not defective:
• Main switch of the grid
• Power socket and main power switch
Routine maintenance and inspection
Check according to EN 60974-4. Always before use the
machine to check the condition of the welding and
supply lines cable. Do not use damaged cables.
Perform a visual check:
• welding cables
• power grid
• welding circuit
• covers
• control and indicator elements
• general status
