Recommendations on the use of welding modes :
Only qualified and specially trained personnel are permitted to use of the spot-welder. Please observe repair
manuals of respective car- manufacturers before carrying out any welds. The correct application of
instructions specified in the user manual and commitment to the indications of the manufacturer as well as
the necessary preparations, implementations and tests of welding jobs lies within the responsibility of the
user.
Several welding modes are available on MI200T spot welding machines.
The STANDARD and MULTI modes allow programming the machine by entering sheet thickness and type of steel.
The MANUAL mode allows programming individually each welding parameter according to the car manufacturer’s
specification: welding current, welding time, clamp force.
The AUTO, ENERGY, and CAR MANUFACTURER modes are available on MI200T models only.
The AUTO mode allows welding without entering any parameter inside the machine. This mode may be used on all welding
spots identified as non-critical by the car manufacturers. For the welding spots identified as critical by car manufacturers,
refer to their repair specification, and use either the MANUAL mode or the CAR MANUFACTURER is mode. In the MANUAL
mode, the exact welding parameters from the repair specification may be entered. In the CAR Manufacturer’s mode,
welding parameters approved and sometimes requested by car manufacturers are saved and can be recalled.
In order to safeguard the quality of each welding spot we recommend carrying out 2 sample welds and a pull out test with
the same steels and applying the same distance from one another required by the job. The welding spot is acceptable if the
pull-off leads to the extraction of the nugget and the tearing of the steel, with a minimum nugget diameter in accordance
with the car manufacturer specifications.
