Welding parameters
The visibility of the arc reduces the need for the user to strictly
observe the adjustment tables as he can directly monitor the
weld pool.
- The voltage directly affects the appearance of the bead, but
the dimensions of the weld bead can be varied according to
requirements by manually moving the torch to obtain variable
deposits with constant voltage.
- The wire feeding speed is proportional to the welding current.
Fig.2 and 3 show the relationships between the various welding
parameters.
Fig.2 Diagram for selection the of best working characteristic.
Fig.3 Relationship between wire feeding speed and current
amperage (melting characteristic) according to wire diameter.
