Appeal 2006-2619
Application 10/935,566
is the remote operation of a welding device (Niedereder, col. 1, ll. 51-63).
Thus, we find that one of ordinary skill in this art would have considered the
disclosure of the reference in the context of a welding device which
includes, among other components, “a welding current” source, that is, a
welding power supply. In this respect, Niedereder would have disclosed to
this person that the “[t]he invention related to a welding device having a
current source” and other components including “a control and evaluation
unit” and “a communication interface,” wherein the “system is that data can
be forwarded to the welding device from a remote site” (Niedereder, e.g.,
col. 1, l. 66, to col. 2, l. 61).
Indeed, the system can be used in “a method of operating a welding
device wherein this method includes the steps of controlling an energy
source via a control or evaluation unit to apply electrical energy to at least
one electrode,” wherein the “control and evaluation unit can process
software modules and operates on the basis of a pre-set set of instructions
and any specific settings entered” to configure the energy source
(Niedereder, col. 4, l. 66, to col. 5, l. 19). We find that Niedereder further
would have disclosed with respect to Fig. 1, a “welding device 1
[comprising] a current source 2 with a power component 3, a control and/or
evaluation unit 4,” and that “the current needed to generate an arc 15
between the welding wire 13 and a workpiece 16 is fed via supply line 17,
18 from the power component 3 of the current source 2 to the welding torch
10 and the welding wire 13” (Niedereder, col. 6, ll. 29-49; see also col. 9, ll.
49-64). In this respect, input and/or output device 22 can be used to set a
range of welding parameters and operating modes which are forwarded to
