Make sure that the welding machine is installed according to the explanations included
on Page 22.
By considering the desired welding current values, install the work cable to the proper
located in front of the power unit by using the
fitting screw at the end of work cable.
Inductance is a mechanism that stabilizes the welding current and used for minimizing
the splashings in the welding seam. It is recommended to use low value inductance
outlet ( ) for welding current up to 250 amperes and to use high value inductance
outlet (
) for welding current higher than 250 amperes.
Connect the work cable holder to the clean surface of the workpiece to be worked on.
Make sure that the contact between them is as good as possible.
Start the machine by turning the

Welding voltage value is approximately set with
and precisely set with
(Refer to
the table on Page 21). These switches are located in front of the power unit.
Place the

to
position. Coolant pump will start to operate.
Value of welding current directly depends on the wire feeding speed value. Select the
proper wire feed speed with the
located in front
of MasterFeed MF-3 wire drive unit. Wire drive speed can be set between 1 - 24
m/min.
You can start welding procedure by following related rules.
