Front Control Panel Fp122 - Selco Genesis G 200 TLH Instruction Manual

In 4-stroke, the first time the button is pressed the gas flows
for the manual pre-gas time; when the button is released, the
arc is struck. If the button is pressed again and definitively
released, the current slope-down and post-gas time begin.
In BILEVEL the welder can weld with 2 different currents pre-
viously set via S5.
The first time the torch button is pressed, the pre-gas time is
run, the arc is struck and welding is performed with the initial
current.
The first time it is released, slope-up to current "I1" occurs. If
the welder presses and quickly releases the button, the
machine will go to "I2"; by pressing and quickly releasing the
button it returns to "I1" and so on.
If the button is pressed for longer, the current slope-down
begins which leads to the final current.
When the button is released the arc goes out while the gas
continues to flow for the post-gas time.

S4: Welding procedure selection key
Permits selection of the welding procedure.
Switch-on of the led at the side of the symbol confirms the
selection.
Procedures:
- MMA (electrode)
- TIG LIFT-ARC start
- TIG HIGH FREQUENCY start
*
S5: SET-UP/parameters key
Permits access to the SET-UP and welding parameter values.
When pressed at switch-on, it permits access to the set-up
parameters while the software version appears on D1.
If pressed after the end of the welder switch-on procedure, it
selects in sequence the welding parameters presented in the
graph G1 with value shown by D1 and variable with E1.
