Firstly, weld current is supplied on the first selected SCHEDULE No. and then
on the consecutive 5 SCHEDULE No.’s including the first selected No. in turn .
In this occasion, weld current is supplied through the transformer selected at
Transformer No. (TR#) in each SCHEDULE Screen.
That is to say, in the case that the supply of weld current is started in the
condition of SCHEDULE No.2 selected, firstly weld current is supplied on
SCHEDULE No.2, then SCHEDULE No.3, SCHEDULE No.4, SCHEDULE
No.5, lastly on SCHEDULE No.6.
For example, Supposing that SCHEDULE No. is 2 (SCH2) and Transformer No.
is 1 (TR#1), similarly SCH3-TR#4, SCH4-TR#5, SCH5-TR#2, SCH6-TR#3,
the time chart where the supply of weld current is started is shown as follows.
As Transformer 1 (TR#1) is set for the first SCHEDULE No.2 (SCH2), weld
current is firstly supplied through the transformer connected to Transformer 1
of Transformer Selector MA-650A, and then through Transformer 4,
Transformer 5, Transformer 2 and Transformer 3 in turn.
