10 CONNECTION WITH OTHER EQUIPMENTS
10.1 SWITCH ON P BOARD
N.B.1)Where upslope and downslope time are to be 0 second, use the slope “SW1"switch mounted in
PC board TSMPA015
口
.(
The switch is set to "ON” position at shipment.)

Ensure correct application of the voltage reducing device by the "SW2"switch in PC board TSMPA015
口
.
★ “OFF”:Voltage reducing device in not activated.
★
“ON”
：
Voltage reducing device is activated.
(The switch is set to“ON”position at shipment.)

Change of arc start process(When EP arc starting process is selected.)
On arc starting, the po)voltage is supplied to welding torch.
(E.P.arc start process)
But when you want to operate ordinary arc start process(E.N.
arc start process),change “EP
0N/OFF” switch on the front panel.
[Caution of E.P. arc start process]
In case of E.P. arc start process, when the arc is generated at the same position repeatedly, the arc
may not be generated smoothly.
In this case, change "EP ON/OFF" switch on the front panel to "EP OFF" side.
At shipment, EP ON/OFF switch is set to "OFF"side.

Change of arc start hard/
soft……SW3(In PC board TSMPA015
口
)
On AC TIG welding, change of arc start current is selected.
At shipaent.arc start hard/soft switch is set to
“soft” side.
Hard
：
Thick work or Thick electrode
Soft
：
Thin work or Thin electrode

Change of H F
Recovery on/off……SW10
（
In PC board TSMPA015
口）
If no-arc occurs in build-up welding, welding at low welding speed(i.e. after heat welding) or welding of
aluminum cast metal or aluminum bronze,
switch to the "ON” side.
Caution:
Do NOT connect any measuring instruments to the secondary side or perform AVC control(arc voltage
control).High-
frequency voltage is applied after the current detection if the switch is in the "ON”
position.(Failure to follow the instruction can damage the measuring instrument or the machine.)
