The contents of this chapter are of vital importance and the-
refore necessary for operation of the warranties. The manu-
facturer accepts no liability if the operator fails to observe
the above precautions and instructions.

4.0 MACHINE DESCRIPTION

The Genesis 200 TLH and Genesis 202 TLH power sources offer
excellent performance in the following welding procedures:
- MMA;
- TIG with remote arc striking with high frequency (TIG HF-
START) and gas delivery control via torch button;
- TIG with contact start with reduction of short circuit current
(TIG LIFT-START) and gas delivery control via torch button.
The Genesis 200 AC-DC and Genesis 202 AC-DC units also
permit welding in TIG AC with square, sinusoidal and triangular
wave.
In inverter welders the output current is insensitive to variations
in the power supply voltage and length of the arc and is per-
fectly levelled, providing best weld quality.
The power source features the following devices:
- a positive socket (+), a negative socket (-) and a central soc-
ket for connection of the TIG torch
- a front control panel with socket for remote controls
- RC16 potentiometer remote control for MMA and TIG wel-
ding
- RC12 pedal remote control for TIG welding
- a rear control panel with gas socket.
The Genesis 200/202 TLH e 200/202 AC/DC can be supplied
with WU15 cooling unit for liquid cooling of the TIG torch.
The Genesis 202 TLH and Genesis 202 AC-DC can be connected
to 115Vac or 230Vac single phase power supply voltages.
An electronic circuit automatically changes the protections, the out-
put current ranges and the characteristics of the generator.
When the Genesis 202 TLH and Genesis 202 AC-DC are
powered at 115Vac, the cooling unit is de-activated.

4.1 Front control panel

and Genesis 202 TLH (fig. 1)

*
L1: Power on: green led
Comes on when the ignition switch on the rear panel (Fig. 3)
"I1" is in position "I". Indicates that the system is on and
powered.
20
*
L2: Protection device: yellow led
Indicates cut-in of the thermal protection device or protection
due to incorrect power supply voltage. With L2 on, an alarm
code blinks on D1. The power source remains connected to
the mains but does not deliver power at the output. If an
overtemperature has occurred, L2 remains on until the inter-
nal temperatures have returned to normal; in this case, leave
the power source on and wait for the welder to cool. In the
event of alarms connected to the mains voltage, press any
button to resume operations.
* Alarm codes
The following alarms are provided:
10 thermal alarm
11 power supply voltage too high (only AC-DC)
12 power supply voltage too low (only AC-DC)
20 serial memory error (chip ST24C16 8 pin)
24 the remote control has not yet been calibrated; this hap-
pens when testing has not been performed or there are
problems with the serial memory.
Solution: enter parameter 66 with a remote control con-
nected and set to scale end.
25 serial memory fault: storage not performed correctly. It
may be necessary to replace the non-volatile memory
(chip ST24C16 8 pin).
*
L3: Voltage output (work): red led
Indicates presence of voltage at the output.
* Display D1
Displays the welding current or value of the welding parame-
ter chosen via S5 on the graph G1. It is used to show alarm
and error messages and to enter the set-up parameters.
* E1: Encoder for entering the welding current, welding para-
meters and set-up values
Allows you to change the value shown in D1 of the parame-
ter selected via S5 in graph G1 (also during welding).
Allows you to enter the required set-up line and vary the
value.
Allows you to continuously adjust the welding current both in
TIG and MMA. (This current remains unchanged during wel-
ding when the power supply and welding conditions vary
within the ranges declared in the technical specifications).
In MMA the presence of HOT-START and ARC-FORCE means
that the mean output current can be higher than the one set.
*
S1: Current regulation system key
Selects the welding current regulation system:
- from front panel in "internal" mode
- from remote control in "external" mode
In this case via E1 it is possible to enter the maximum current
value that can be selected via the remote control.
*
J1: 7-pole military standard connector
For connection of the remote controls RC16 and RC12.
*
S2: Key for selecting type of TIG welding current
- CONSTANT current with or without SLOPES.
- PULSED current with or without SLOPES.
- MEDIUM FREQUENCY current with or without SLOPES.
Switch-on of the led at the side of the symbol confirms the
selection.
*
S3: Key for selecting control mode in TIG
- 2-stroke welding (2T)
- 4-stroke welding (4T)
- 2-level welding (BILEVEL)
Switch-on of the led at the side of the symbol confirms the
selection.
With the RC12 pedal control, only the 2T mode is possible.
In 2-stroke, when the button is pressed the gas flows and the
arc is struck; when the button is released, the current goes to
zero in the slope-down time; once the arc is off, the gas flows
for the post-gas time.
