• Light separating screen should be put in the job
site to prevent arc hurting other people;
• Inflammable or explosive materials are prohibited
to access the job site;
• Every connector of welder should be connected
correctly and grounded reliably
• Manual Arc Welding
When put 'welding mode selection switch' on
'arc welding' and Dc/pulse select switch on DC
position, it can be used as manual arc welding.
Choose Parameter setting knob enter into welding
current parameter setting to adjust welding cur-
rent and also can enter into pushing force current
parameter setting to adjust pushing force current.
