3.5.4 Argon gas regulator (YX-251A)
The maximum flow rate is 25L/min.
3.5.5 Cooling water unit and cooling water
(1) Cooling water unit (with built-in flow-rate switch)
(2) Cooling water
Use our genuine cooling-water (Pana-coolant K),
which keeps its quality for a long time.
Product number: CWU00098
(Service temperature: -20 to +90 deg-C)
3.5.6 Potentiometer-type remote control unit (YC-30BPR1,YC-30BMR1)
(1) The remote control unit enables you to set the pres
-
ence, absence or repeat of the crater control and the
presence or absence of the pulse control, and to adjust
the initial current, welding current, crater current and
pulse current (Only YC-30BPR1) at a distance. (Cable
length: 5 m)
YC-30BPR1
YC-30BMR1
* After connection of the remote control unit, such
setting and adjustment can be done via the remote con
-
trol unit only.
(2) To have a current value displayed when adjusting each
current, switch the LCD display to the screen of each
current item. Then, the current value of each item
appears on the set-value display.
* Details: See chapter 6 (Name and function of each
part) and chapter 9 (Operation).
* It is also possible to make the adjustment of each
current without switching the LCD display to the screen
of each current item. (In that case, however, no current
value appears on the set-value display.)
(3) As the analog input is employed for the input of current
values from the remote control unit, current values
appearing on the set-value display may vary by about
plus or minus 1A. (It becomes stable if you change the
position of a potentiometer slightly.)
3.5.7 External equipment connection unit (YX-CB009)
• This connection unit enables this welding power source
to change over the pages of stored welding conditions by
connecting with external equipment (sequencer).
• The sequencer is not included in this welding power unit
and the attachment unit.
• When using this connection unit: See”Connection: Con
-
necting to external equipment connection unit”
Note
Cooling water unit
(Product number: YX-09KGC1)
• No flow-rate switch is incorporated in this welding power unit.
• When using a water-cooling torch, use the cooling-water system with a flow-rate switch incorporated to prevent the
torch from burnout.
• Connect the cable of the flow-rate switch to the “water circulation path” terminal of the jig terminal block within this
welding power unit.
Note
TIG welding remote control unit
The conventional YC-301URTRK1 cannot be used. (Due to the difference in connectors and signal lines)
Note
Observe the followings to prevent troubles caused by the incorporation of high frequency waves.
• Keep the signal line connected to the external-equipment attachment unit away from the welding arc area, welding
torch, base-material-side cable, base-material grounding wire, power input line, grounding wire, etc.
• The length of wiring shall be 10m or shorter.
• Make sure to connect the grounding wire of this welding power unit to the ground.
