WARNING: DO NOT TAP the electrode on the piece; this risks
damaging the coating and making arc strike difficult.
MANUALE ISTRUZIONE
- As soon as the arc has struck, try to keep at a distance from the
piece equivalent to the diameter of the electrode being used and
keep this distance as constant as possible while carrying out the
weld; bear in mind that electrode inclination in the direction of
progress should be about 20-30 degrees (FIG.Q).
