Lincoln Electric IM558 Synergic 7 and 7H Water Cooled - Manual (Page 9)

A-2 INSTALLATION
SYNERGIC 7 & 7H
A-2
GENERAL DESCRIPTION
The Synergic 7 is a CSA / NRTL/C certified semiautomatic
constant speed wire feeder designed specifically for use
with the Invertec Power Wave type power sources. A serial
communication link is supplied through the input control
cable of the Synergic 7 enabling information to be shared
between the power source and wire feeder. The Synergic 7
comes factory equipped with a gas solenoid valve with gas
fittings, Euro-style Fast-Mate™ gun connector, and factory
equipped with a water connection kit for water cooled guns.
These models includes a 3-1/2 digit LED display with rotat-
ing knob encoder controls for setting the wire feed speed
and voltage and a dual procedure selector switch. A tac-
tile-feel keypad provides selection of operating mode, func-
tion selection, timer and crater fill selection and parameter
adjustment. Two keys provide Cold Feed and Gas Purge
functions, and connector receptacles are provided for an
optional dual procedure remote control and dual procedure
switch.
The unit has 3 operating modes: 2-step trigger, 4-step trig-
ger and spot. Three functions can be selected: Volts or
Trim Preset/arc (memory) voltmeter, Run-in speed and weld
speed (IPM or m/min.) or (memory) ammeter. In addition,
when 4-step trigger mode is selected, crater fill WFS is also
adjustable. Up to three timers are available depending on
the mode: preflow, postflow and spot, and 5 acceleration
rates are selectable, as well as 6 Burnback settings.
The Synergic 7 Water Cooled is available in 2 models:
b) Feeds .045 - (1.2mm) cored wire for Outershield
GMA or Innershield processes.
Recommended power sources are The Lincoln
Electric Company Synergic type Invertec® Power
Wave power sources with 42VAC auxiliary power, and
a 14-pin connector receptacle.
STANDARD FEATURES
Wire Drive Features:
Wire Drive Unit - Incorporates low voltage permanent
magnet motor and highly efficient two-reduction spur
gearbox which operates in any position. The non-fluid
lubricant wonʼt leak.
“Quick Release” Wire Feed System - Provides a
completely tool-less means for releasing and opening
the idle roll pressure arm, precisely adjusting the idle
roll pressure and changing the incoming and outgoing
guide tubes and drive rolls.
Drive Rolls and Guide Tubes - Provide long life,
positive feeding and precise alignment of electrode.
Minimizes “birdnest” or mill-thru of wire if properly set.
(Ordered separately.)
Fast-Mate™ (European Style) Gun Connector -
Provides for electrode, shielding gas and gun control
leads for connections in a single connector.
Tachometer Feedback - Provides proper wire feed
acceleration and speed accuracy, independent of fluc-
tuations in line voltage and wire loading, for reliable
arc starting and weld consistency.
Run-in Speed Setting - Allows the arc striking speed
“Run-in” to be adjusted independently of the weld feed
speed for starting optimization.
Cold Feed Speed - Provides cold feed speed adjustment
independent of weld, run-in and crater speeds.
Selectable Acceleration - Provides front panel selec-
tion of 5 acceleration rates. This feature in combina-
tion with Run-in Speed provides the ability to easily
optimize starting on any process or procedure.
Solid-State Dynamic Braking - Quickly stops wire feed
motor to minimize wire overrun during weld termina-
tion. Solid-state design requires no maintenance.
