Switching on function SYNERGIC
Press button SYN until you switch on LED SYN and LED material thickness.
Function SYNERGIC is on.
Program choice ‐ adjustment of wire diameter and gas type
Press button SET until you switch on LED marked in the picture.
Using the potentiometer, you shall choose gas type you are going to apply ‐
CO or Ar (marks MIX argon and CO

Press button SET until you switch on LED diode marked in picture.
Use the potentiometer, thus you shall choose wire diameter SG2 you are
going to use ‐ 0.6 ‐ 0.8 ‐ 1.0 mm.
Approximate thickness of material possible to weld according to current
adjustment will be shown on upper display. Currently adjusted speed of wire
shift will be shown on bottom display, which is changed automatically when
you change positions of voltage switch. Fall or rise in welding capacity is ad‐
justted with a voltage switch.
Switching function SYNERGIC OFF
Press button SYN. Diode SYN and material thickness will switch off.
Function SYNERGIC is off.
NOTE 1: Shown values of material thickness are only approximate. Thickness
of material can vary according to welding position etc.
NOTE 2: To correct parameter for wire shift, you shall use a potentiometer or
buttons of remote control UP/DOWN.
NOTE 3: Parameters of the program synergic function are designed for copper
coated wire SG2. In order to reach the correct function of the synergic pro‐
grams, it is necessary to use quality wire, protective wire, gas and welding
material.
NOTE 4: In order to reach the correct function of the synergic machine it is
necessary to keep prescribed diameters of cables to wire diameters and the
right die otherwise the correct function of the machine is not guaranteed.

Further on, it is necessary to secure quality power supply ‐ 400A, max. +/‐ 5%,
connecting to ground of the welding material (use an earthing clip directly on
the welding material).
RECORGING OWN PARAMETERS OF THE SPEED OF THE WIRE SHIFT INTO
MEMORY
The function of storing parameters is on only if the function synergic is on.
1. Choose the required speed of the wire shift.
2. Press and hold the button SYN and then.
press the button test gas (MEM)
3. Release both the buttons ‐ new parameters are stored.
All the required parameters can be stored and rewritten in this way as ne‐
cessary. The recorded parameter is adjusted always in the same position of
the voltage switch when the parameter was stored.
A return to original parameters synergic adjusted by the producer is done by
the follow‐up pressing and holding the button SYN and then pressing and
releasing the button of wire threading. In such a way it is possible to return
single parameters which have been stored.
A total return of all the pre‐adjusted values to the values set up by the produ‐
cer can be done through the function factory configuration.
FUNCTION LOGIC ‐ ONLY WITH MACHINES PROCESSOR AND SYNERGIC
Function LOGIC includes a file of simplifying and clarifying points which
present adjusted and currently set values.
If two displays show a few different parameters, it is necessary to simplify
presentation of parameters. Function LOGIC operates just in this way ‐ it ma‐
kes everything clear and distinct:
•
Upper display switches on during welding process only when electronics
makes measurements and shows welding current A (in case there is no
mode SYNERGIC on with machines Synergic. In case there is mode
SYNERGIC on with machines Synergic, display is lit up constantly and only
shown values change). After approx. 7 sec. display switches off automati‐
cally again. Thus electronics increases orientation while reading parame‐
ters during adjustment.
•
Upper display shows only welding current. When function synergic is on
(only with machines Synergic), upper display shows thickness of material.
•
Bottom display shows welding voltage while welding and other values ‐
time, speed etc. during adjustment.
•
LED SETTING will switch off during welding process only when a digital
voltampermeter is used.
•
LED SETTING is on during welding only when operating staff is adjusting
and changing speed of wire shift with a potentiometer or a remote cont‐
rol UP/DOWN. As soon as operating staff stops adjustment of a parame‐
ter, LED SETTING will be switched off automatically within 3 sec. and dis‐
play shows value of welding voltage.
Recommended adjustment of welding parameters see charts on pg. 55 ‐ 60.
PRINCIPLE OF MIG/MAG WELDING
Welding wire is lead from the roller into the flow drawing tie with the use of
the feed. Arc joins thawing wire electrode with welding material. Welding wi‐
re functions as a carrier of the arc and as the source of additional material at
the same time. Protective gas flows from the spacer which protects arc and
the whole weld against the effects of surrounding atmosphere.

Welding work cycles
Welding machines work in four working cycles:
•
continuous two‐cycle time
•
continuous four‐cycle time
•
spot welding two‐cycle time
•
pulse welding two‐cycle time
Adjustment of the machines for these work cycles is done through two swit‐
ches with potentiometers (pic. 1 pos. 6 and 7). On the control panel there are
shown their functions in schemes.
TWO‐STROKE CYCLE
During this function both potentiometers are always switched off. Welding
process is started by only the pressing the switch of the torch. The switch
must always be held during the welding process and it can be interrupted
releasing the switch of the torch.
