JEONGWOOD TSA-500, Инструкция по эксплуатации

Страница: 12 / 13

This is further technical information about TSA-500 AC type Spot Welding Machine and
there are two methods to control weld current by SCR and/or voltage selector.
A) Voltage Select Switch at Weld Transformer
To increase weld power, it is required to change voltage select switch from level 1 to
level 4 at weld transformer. Changing this switch, voltage will be changed as below.
Level 1 …… 2.5V
Level 2 …… 2.93V
Level 3 …… 3.5V
Level 4 …… 4.4V
B) Setting Method of Weld Controller
1) Though it is shown as “set figure into 0” on operation manual, it is required to
adjust this figure depends on weld material .
2) The meaning of “40” at “HEAT1” is 40% power of total 100%. If is set at “0”,
there will be no weld power. Higher figure means higher weld current flowing
to transformer. Changing 40% into 45%, weld output is increasing too. In case
“40%” is an ideal weld condition, 45% or 50% will result excess of weld output
and it may cause weld splash, excess melt and weld electrode may be easily
worn out. CYCLE(∽) means time to flow output current.(1 cycle = 16ms)
Higher cycle means more time to flow weld current.
3) Once started, it is available to get three output HEAT1, HEAT2 and HEAT3.
When it is set on “0”, there will be no output. In case thick material, it is
recommended to use HEAT1 and HEAT2 instead of HEAT1 only. When HEAT1
and HEAT2 are used, HEAT2 must be higher than HEAT1, and COOL time is also
required.
4) When CYCLE(∽) has increased, weld time will be prolonged and it may cause
material oxidization or excess melt. So, it is recommended to adjust as less
CYCLE(∽) and higher current(%). It is also recommended to start with low
figure and increase to high figure. When weld pressure has increased, weld
current must be also increased.
