Continuous Wire Welding (Mig/Mag) - voestalpine bohler welding URANOS NX 2200 PMC Manual De Instrucciones

OPERATING INSTRUCTIONS
The electrode must be sharpened as shown in the figure.
EN
Filler metal
The filler rods must have mechanical characteristics comparable to those of the parent metal.
Do not use strips obtained from the parent metal, since they may contain working impurities that can negatively affect the
quality of the welds.
Shielding gas
Typically, pure argon (99.99%) is used.

The current is transferred to the arc through the fusible electrode
In this procedure the melted metal is transferred onto the workpiece
through the arc stream.
The current is transferred to the arc through the fusible electrode
is transferred onto the workpiece through the arc stream. The
automatic feeding of the continuous filler material electrode (wire)
is necessary to refill the wire that has melted during welding.
