CONNENCTION
FLOW SWITCH (OPTIONAL):
This connector is part of the optional Coolant Flow Switch Kit and is used to transfer a
signal from the flow switch (not shown) to the control, indicating whether suitable coolant flow is
present or not. The flow switch is mounted in-line with the coolant supply line. When there is
sufficient coolant flow through the flow switch (setting adjustable by the operator) a relay closes.
The PIPE KAT
®
control will not allow a weld cycle to start, or continue, unless it sees that relay
is closed (or the signal bypassed when this optional kit is not installed).
NOTE: the remote flow switch is only available on units that have the remote
water cooler start option installed
SHIELDING GAS INPUT:
Shielding gas supply is connected here. The PIPE KAT
®
Main Control energizes an
electric solenoid valve to open the gas flow for pre-flow, welding, post-flow and manual purge
operation.
