8. Parameters & its Operational meaning
Shielded Manual Metal Arc Welding (SMAW) or Electric Welding can be done by this Power Source.
TIG welding process can be done by lift arc or scratch arc process.
Welding parameters can be adjusted with the help of various pots available on the front panel.
a) WELDING CURRENT : Welding current of the welding process can adjusted with Welding
current pot Pot as per below chart :

a)
ARC FORCE : Arc force is the extra voltage required during welding when welders hand is
becoming up & down . It is in the percentage graduation according to arc voltage. It can be
adjusted with the help of ARC FORCE POT provided on the front panel of the machine.
b) START CURRENT : Start current is extra initial current to smooth start of welding. It is in the
percentage as per welding current
