K283-1 APPLICATION
For accurate control of welding procedures on constant voltage (CV)
systems, use Lincoln’s K283-1 wire feed speed meter.
The wire feed speed meter is a hand-held portable unit that can be
placed on .030” to 7/32” (0.89 to 5.6 mm) diameter automatic or
semiautomatic wire to measure wire feed speed in inches per minute.
The unit can be used on any wire feeder where there is access to the
wire.
DESCRIPTION
When the meter is used, a spring loaded guide keeps the pickup disk
on the wire to ensure accurate measurements. The speed is shown
on a digital readout and is accurate within ±1% over a normal range
of 100 to 600 inches per minute. The pickup disk and guide are
insulated from the case so the unit can be used when the wire starts.
The meter displays the wire feed speed continuously and
automatically updates reading very second. The last reading will be
displayed for approximately 2 minutes before unit shuts off
automatically.
The K283-1 is battery operated and can be operated in an ambient
temperature of 32º to 120ºF (0º to 49ºC). Storage temperature range
is -30º to 120ºF (-34º to 49ºC). A case is provided for storage when
the meter is not in use.
INSTALLATION
Batteries are shipped loose and should be installed per instructions
below.
If the wire feed speed meter is not to be used for several months,
remove batteries from the unit to prevent corrosion.
OPERATION
pen the guide with attached spring handle and place pickup disk on
wire so that guide traps the electrode against the disk. The disk must
be kept square with the wire for accurate readings. Brace meter
against wire feeder case or something stationary so unit does not
move while reading wire speed.
Push the button on the side of the unit to have the digital display read
wire speed in inches per minute.
To measure wire feed speed on the LN-22 and LN-23P place this
pickup disk directly on wire emerging from the welding gun (or from
feeder, if gun is removed).
For maximum life, the wire feed speed meter should be removed from
the wire after wire speed has been determined. Leaving the meter on
the electrode continuously can lead to reduced guide life and expose
the meter to mechanical abuse.
A flashing “B” indicates batteries are low and they should be replaced
with two AA alkaline batteries. If there is no display and if
temperature is below 32ºF (0ºC), warm up unit until display returns.
Be certain that batteries make a good electrical connection with
battery terminals and spring contacts.
