Note:
The list of available programs depends on the
power source.
Procedure of begin welding of SMAW process:
•
Connect Lincoln Electric power sources using
ArcLink
®
protocol to communication to wire feeder.
•
Determine the electrode polarity for the electrode to
be used. Consult the electrode data for this
information.
•
Depending on the polarity of using electrode,
connect the work lead and the electrode holder with
lead to output sockets and lock them. See the
Table 14.

•
Connect the work lead to the welding piece with the
work clamp.
•
Install the proper electrode in the electrode holder.
•
Turn the input power ON.
•
Set the SMAW welding program (1, 2, or 4).
•
Note:
The list of available programs depends on the
power source.
•
Set the welding parameters.
•
The welding machine is now ready to weld.
•
By applying the principle of occupational health and
safety at welding, welding can be begun.
For 1 or 2 program can set:
•
Welding current [9]
•
Switch on / switch off the output voltage on the
output lead [10]
•
Wave Controls:

For 4 program can set:
•
Welding current [9]
•
Switch on / switch off the output voltage on the
output lead [10]
•
Wave Control:

ARC FORCE
ARC FORCE -
the output current is temporarily
increased to clear short circuit connections between the
electrode and the workpiece.
Lower values will provide less short circuit current and a
softer arc. Higher settings will provide a higher short
circuit current, a more forceful arc and possibly more
spatter.

– value in percentage of nominal value
welding current during arc start current. The control is
used to set the level of the increased current and arc
