ORDINARY AND EXTRAORDINARY MAINTENANCE
Frequently check the correct functioning and the status of both control devices and relevant connecting cables.
Do not wash the control unit with water which could enter it; avoid strong solvent, thinner and gases which could
damage the plastic components of the control unit.
The built-in ammeter is calibration-free. In any case, its working efficiency should be checked by comparing the
measurement of the TE470/TE480 with that of another instrument. The built-in ammeter measures the current's
real effective value (RMS) (see chapter "WELDING CURRENT AND CONDUCTION ANGLE MEASURE"). The
instrument used for comparison should be able to perform the same type of measurement.
