NOTE: TRAVEL AUTO and TRAVEL ON should not be closed at the same time. Either one OR the other should
be closed at any time, and must remain closed to keep particular Travel Mode active. If neither switch is closed at
any time, travel will be turned OFF, regardless of the welding state. Inching and Flux switches will activate their
particular function when the switch is closed, and will cease when opened. The START and STOP switches are
MOMENTARY and only need to be closed for a short period of time to start or stop the weld sequence.
CONTROLLING NON-LINCOLN
AUXILIARY EQUIPMENT:
Custom motion control and/or other auxiliary equip-
ment can be powered using the terminal strip and
relays. To use non-Lincoln motion control and/or flux
hoppers, follow instructions below.
1. Remove all input power to the POWER FEED™
10A CONTROLLER including any auxiliary power
supplies.
2. Remove the wire duct cover to gain access to the
leads on the right side of the terminal strip.
3. Remove one of the plug buttons located on the bot-
tom of the POWER FEED™ 10A CONTROLLER
control box and install some type of strain relief for
the auxiliary control leads.
4. Remove the leads going from the terminal strip to
the corresponding connectors, i.e. terminal strip
blocks #11, #13, and #16 for the 4-pin TC-3 Travel
Carriage or terminal strip blocks #19, #20, and #23
for the 3-pin Automatic Flux Hopper.
5. These loose leads can be taped and secured in the
wire duct.
6. Any custom or non-Lincoln equipment can be pow-
ered by the normally open contacts from relays
CR1, CR2, or CR3. The normally open contacts for
CR1 are located on terminal strip blocks #5 and #6.
The normally open contacts for CR2 are located on
terminal strip blocks #12 and #13. The normally
open contacts for CR3 are located on terminal strip
blocks #19 and #20. CR1 and CR2 are BOTH
turned ON when the weld sequence starts and are
BOTH turned OFF when the weld sequence stops
as long as the TRAVEL MODE Switch is in the
AUTO position.
7. The input supply voltage to power these devices is
provided by the end user. As shipped, the PF-10A
has the auxiliary supply blocks (terminal strip blocks
#48 and #49) connected to the CR2 relay and CR3
relay inputs, respectively. When the end user con-
nects a supply to the AUX blocks #48 and #49, this
voltage will be jumpered to the CR2 and CR3 relay
inputs on terminal strip blocks #11, #17, and #18.
Note – the CR1 relay is not connected to the AUX
terminal strip blocks; the customer must connect
power to this relay if it is to be used. See relay rat-
ings listed earlier.
