Parameter Description
PRE-FLOW
This pa r amete r ope r ates in all weld modes except Lift TIG mode and
is used to heat up the weld zone in TIG modes o r imp r ove the sta r t
cha r acte r istics fo r stick elect r odes. e.g. low hyd r ogen elect r odes.
It sets the peak sta r t cu rr ent on top of the BASE (WELD) cu rr ent.
e.g.
HOT START
cu rr ent = 130 amps when
BASE (WELD)
= 100 amps
&
HOT START
= 30 amps.
INITIAL CUR.
This pa r amete r ope r ates in

REPEAT
(4T) TIG modes only and
is used to set the sta r t cu rr ent fo r TIG. The Sta r t Cu rr ent r emains on until
the to r ch t r igge r switch is r eleased afte r it has been dep r essed.
UP SLOPE
This pa r amete r ope r ates in TIG modes only and is used to set the time
fo r the weld cu rr ent to r amp up, afte r the to r ch t r igge r switch has been
p r essed then r eleased, f r om INITIAL CUR to PEAK o r BASE cu rr ent.
This pa r amete r ope r ates in TIG modes only and is used to p r ovide gas
to the weld zone p r io r to st r iking the a r c, once the to r ch t r igge r switch
has been p r essed. This cont r ol is used to d r amatically r educe weld
po r osity at the sta r t of a weld.
