6) OPERATION
1) Connect the return cable to the work piece.
2) Turn the circuit switch to "1" there by connecting the transformer to the mains.
3) Make sure that the air inlets are not blocked.
4) Adjust desired welding current setting with the crank on the top the transformer.
Note 1:
When used in 220V (power supply) the maximum current is 225A.
Note 2:
When used in 110V (power suply) the maximum current is 110A.
7) MAINTENANCE AND SERVICE
The transformers require a minimum of maintenance. Under normal conditions, it is sufficient to blow the
transformer clean with dry compressed air with reduced pressure once a year. If used in a dusty and dirty
areas, it must be cleaned more often.
