"Wire speed / welding parameter setting" rotary dial
Infinite adjustment of the wire speed or welding current, sheet metal thickness, JOB
and runtime parameters such as gas post-flows, wire burn-back, etc.
"Operating mode" key button
Non-latched
Latched
MIG spots (parameter selection t1 is carried out using the "Runtime
parameters" button, setting on the "Rotary transducer".
Interval (parameter selection, t1 = pulse time, t2 = pulse pause, carried out
using "Runtime parameter" button, setting on the "Rotary transducer".
"Runtime parameters" button
The parameters are set on the rotary transducer
Gas post-flow time (0.0 s to 10.0 s)
Wire burn-back (-50% to +50%)
Spot time / pulse time (0.1 s to 5.0 s)
Pulse pause (0.1 s to 2.0 s)
"Top" display
Display of the welding voltage, correction value for the wire speed or parameter
designations for runtime parameters.
"Down" display
Display of wire feed speed, welding current, sheet metal thickness, JOB number and
runtime parameters.
"Voltage" signal light
On when the welding voltage or open circuit voltage is displayed.
"Wire correction" signal light
On when the correction value of the wire speed is being displayed.
"HOLD" signal light
After each completed welding process, the last parameter values used for the welding
process are shown on the display; the signal light is on.
"MANUAL" signal light
Signal light is on when the machine is not in JOB mode. All parameter settings are
carried out "manually" by the user (JOB 0).
"Choke tappings" signal light
Depending on the machine design, there are two or three workpiece connection
sockets on the welding machine (choke tappings). The machine displays the
recommended workpiece connection in JOB mode (see relevant images on the
connection sockets).
Choke tapping 1 (hard), workpiece lead connection socket
Choke tapping 2 (medium), workpiece lead connection socket
Choke tapping 3 (soft), workpiece lead connection socket
