GRID CONNECTION
Welding units need an appropriate power supply and
enough capacity to get a highest-performance work. All the
range is certified generator-ready that meet the normative
requirements and correctly work. The minimum power to be
supplied is:

Environmental conditions limitation
The equipment must be installed under its IP21 classification,
which means that the equipment is protected from a maximum
of a vertical water drops fall and the dangerous parts access
with a finger, against strange solid bodies of 12,5mm ø and
bigger.
The equipment is ready for working on a temperature range
from -15º to 70ºC in consideration of the performance drop
limitation (duty cycle) from room temperatures over 40ºC.

4_OPERATING INSTRUCTIONS
PLACEMENT AND TESTING
The unit is on by pressing the switch 7 in all the models. Before
turning the equipment on, verify its safety and fulfil its labour
risks prevention plan. Then, carry out the following explained
functions according to the machine's type of service.
COATED ELECTRODE WELDING (MMA)
Connect the mass cable to the unit connector 4, and the earth
clamp to the workpiece. Make sure there is a proper electric
contact in a clean and solid surface.
Connect the electrode holder mass cable of the unit to the
connector 4. Plug the electrode to the electrode holder clamp,
securing the directional grooves to fit it.
Select the coated electrode mode on the selector 11 and adjust
its intensity with the setting 6. In the MIG350BT/MIG500BT
models, adjust the Arc Force 8, put it on a minimum-medium
for basic electrode and on a medium-maximum for cellulosic
electrode.
Note: The electrode is mostly connected to the positive
terminal (reverse
circumstances though, it should be connected to
the negative terminal (direct polarity), as it usually
happens with the basic electrode. Refer to the electrode
documentation to be assured.
TIG WELDING
It is necessary for you to obtain a TIG torch (ask your
STAYER supplier) whose gas is controlled by a valve placed
in its handle. Connect the TIG torch to the connector 4 and
the mass to the connector 3 of the equipment (direct polarity).
Press the button 11 to MMA mode. Now, the unit will be
regulated only by the amperes control 6. In with HOT START /
ARC FORCE control models put the control 8 at its minimum.
MIG/MAG WELDING
Connect the earth cable 2 to the unit's connector 4. Connect
the torch to the Euro torch output 21 of the unit. Secure the
connection by screwing the connector's safety ring of the
torch.
When hollow-wire is used (flux core, no gas supply needed),
it is necessary to reverse the polarity from inverse to direct
(positive to the workpiece). Use the exchange connection
borne ready for the effect in all the models.
TOOLS REPLACEMENT
It is explained here the consumables replacement from
the three execution devices: electrode holder for coated
electrodes, continuous wire torches in MIG/MAG processes
and tungsten electrodes torches in TIG processes.
MMA PROCESS (COATED ELECTRODE)
Replace the coated electrode by using the 4 pressor grooves
caved on the electrode holder clamp in order to secure the
position and a better electric contact of the electrode. Make
sure the clamp presses the bare metal of the electrode and
there is no 'fake' contact by reaching the metallic soul coating
of the electrode.
TIG PROCESS
The TIG torch tungsten electrode is the wear and tear
element.
