probably set points for welder variables: Crater Amps => amperes cratera

the following are in my reference:

Crater WFS
Crater Trim
Crater Time

Amplificador de cratera?
Voltagem da cratera?
Kwatts da cratera?
Acho que não.

Aqui, no fim da página tem uma imagem com a expressão "trinca na cratera", parece que é terminologia usada na Petrobrás. Espero q ajude. :)

Crater => cratera New Crater Fill Procedure
The Power Wave
®
and Power MIG
®
power supplies
both offer a crater fill function. The crater fill function
works similar to the start function, but in reverse.
Therefore, the starting WFS and trim would ramp
down from the welding WFS and trim over a preset
time after the operator releases the gun trigger.
Now with the TOTAL s2f
™
welding process, the crater
fill function consists of two steps. The WFS and trim
will ramp down to a selected point for half the time set
for crater fill and then will stay at those values for the
remaining portion of the weld, called the cap. This
gives an enhanced and more consistent crater fill
than with previous methods and creates a button of
weld metal.
