Praxair SELECT-400, Operating Instructions Manual

Page: 29 / 62

The small wave symbol on the front panel earth clamp connector indicates that the preferred connection is for “short arc”
welding and aluminium. The connection on the connector with a large wave symbol is used preferably for “spray arc”. The
inductance (IND) limits the short circuit current and ensures welding with a minimum amount of spatter.
A digital measuring KIT can be optionally installed on the front panel, displaying the welding voltage and current.
WARNING!. This machine cannot be adjusted at a distance. If you have acquired the MIG-44 WIRE FEEDER, this has a
potentiometer for regulating the voltage. In this unit the potentiometer is not operative.
