Rear Control Panel; Operation; Cooling Unit Wu15; Remote Controls - Selco Genesis G 200 TLH Instruction Manual

4.2 Rear control panel (Fig. 3)
*
l1: Ignition switch
Controls electric ignition of welder.
It has two positions: "O" off and "l" on.
WARNING
*
With l1 set to the position "l" on, the welder is operatio-
nal and voltage is present between the positive (+) and
negative sockets (-) on the electrode. In TIG the welder
requires the pedal or torch button start for voltage to be
present between the sockets (+) and (-).
*
When the welder is connected to the mains, even with l1
set to the "O" position some of the internal parts will be
live. Carefully follow the warnings given in this manual.
*
1: Power supply cable

2: Gas fitting

4.3 Operation

The machine stores the last welding status and dis-
plays it when switched back on.
* Set the ignition switch l1 to l; switch-on of the power led L1
(green led) confirms that the system is powered.
* The display D1 shows the figure 200/202 and all the leds
come on (for control) for 3 seconds. The leds on the front
panel then go out and D1 shows the welder software version
(e.g. 1.0) for 4 seconds; during this time it is possible:
- to enter the SET-UP mode by pressing the key S5
- or proceed with welding (or parameter variation).
* If chosen, entry to the SET-UP mode is confirmed by a central
0 on the display D1:
- Turn the potentiometer E1: the numbers corresponding to
the parameters appear (in sequence) on the display D1;
stop on the parameter required and press S5. Via parame-
ter (9) all the modifications performed in the SET-UP are
cancelled and you return to the standard values set by
SELCO.
- The number on the display D1 is replaced by the value of
the parameter which is modified via the potentiometer E1.
* If it is necessary to modify the welding parameter values of
the graph G1:
- Let 4 seconds elapse from switch-off of the panel leds; led l
(welding current) will remain on in the graph.
- Press S5; every time it is pressed one of the leds in the graph
G1 will come on (in clockwise sequence) and the value of
the related parameter will appear on the display D1; stop
on the parameter required.
Fig.3
- Turn the potentiometer E1 and modify the parameter value.
- Press the S5 SET-UP/parameters key again to go on to ano-
ther parameter or wait 5 seconds (led "l" in the graph G1
will automatically come back on).
The machine is always ready to weld and the status
is indicated by the set of leds lit up on the panel.
The fan only starts once the system has warmed up.

4.4 Cooling unit WU15

It is optional and permits liquid cooling of the TIG torch. There
is one single electrical connection between WU15 and Genesis
200/202 TLH/AC-DC and once assembled, they form one sin-
gle body.
*
All WU15 replacement, repair or connection opera-
tions must be performed by expert personnel
instructed by SELCO.
*
Filling or topping up of the tank with cooling liquid
must be performed with the power source and
WU15 assembled and positioned on a horizontal
surface.
*
Filling or topping up of the tank must be performed
with Selco cooling liquid, code 18.91.001.
*
In order not to damage the cooling unit, always fit
the by-pass pipe when the torch is not connected to
the cooling liquid inlet/outlet terminals.

4.5 Remote controls

4.5.1 RC16 potentiometer remote control for
MMA and TIG welding
This device allows you to vary, by
remote control, the amount of cur-
rent necessary without interrupting
the welding process or abandoning
the work area. 5, 10 and 20 m con-
nection cables are available.

4.5.2 RC12 pedal remote control for TIG welding

Once the power source has been
switched to the EXTERNAL CON-
TROL mode, the output current is
varied from a minimum to a maxi-
mum value (can be entered from
SETUP) by varying the angle bet-
ween the pedal surface (where the
foot rests) and base. A microswitch
provides the weld start signal at
minimum pressure.
