Before starting the installation,check with the power company to be sure your power supply is adequate
●
for the voltage,amperes,phase,and frequency specified on the welding machine nameplate,Also be sure the
planned installation will meet all local and national code requirements.Some welding machines may be
operated from a single phase line or from one phase of a two or three phase line.
Before connecting the input cable to the power supply,check that the power(on-off) switch operates in
●
the position corresponding to the input voltage that the machine will be connected to.
CAUTION :If the power switch setting does not match the input power voltage,you may burn up the
welding machine!
Connect the "PE" or green/yellow grounding wire in the input cord to a system ground per the
●
applicable national and local codes.

2.3.4 CONNECT THE EARTH CLAMP
●Connect the earth clamp firmly to the welding bench or the work-piece.
●To increase the quality of the welding, earth clamp on the work piece should be clamped tightly and as close to
the welding area as possible. For more detail please refer to the Welding Parameter Selection table.
Do not place the earth clamp on the welding machine or the gas cylinder;
otherwise the welding current will be carried via the protective conductors and
it will destroy these.
