Note : The machines' duty cycle has been tested at room temperature (40°C) and has been determined by simulation.
• These are Class-A devices. They are designed to be used in an industrial or professional environment. In a different en-
vironment, it can be difficult to ensure electromagnetic compatibility, due to conducted disturbances as well as radiation.
CONTROL PANEL (FIG-4):
Welding mode selection / test (1) :
- 2T: two-stage welding / 4T: four-stage welding.
- SPOT: Spot welding with adjustable spot diame-
ter
- Delay: intermittent welding modes for an opti-
mised operating procedure
2 modes to make easier the setting up of the welding
unit: « Manual » or « Synergic ».
- Test function: The LED switches on when you
push the button (1). Read chapter «Welding unit set-
tings»
SPOT / DELAY potentiometer (3): To adjust the wel-
ding time of a point, the size of the point and the time
between each point.
Arc dynamics potentiometer (4): To adjust automati-
cally or manually the arc dynamics.
Metal selection and manual mode (5): Read chapter
«Welding unit settings»
Mode « Synergic » (6): Read chapter «Welding unit
settings»
Wire diameter (7): Select the wire diameter used.
Thermal protection LED (8): Read chapter «Thermal
protection».
WELDING UNIT SETINGS: (FIG-4)
« SYNERGIC » MODE
This function automatically controls the wire speed. There is no need to set the wire speed manually.
- Position the potentiometer (2) in the middle of the « Optimal synergic » zone
- Select: Wire type (5), wire diameter (7), power mode (with the 2 power switches on the front (12)).
From the settings chosen, the unit determines the optimum wire speed and is ready to weld. It is also possible to ma-
nually adjust the wire speed (+ or –) if necessary using the potentiometer (2). The last welding configuration is saved
in the memory automatically (wire diameter, wire type, mode).
Only in the synergic mode, I twill indicate you the thickness you can weld with the parameters
« Test » function
selected without using any gas or wire. These values are calculated on the basis of a welding
on the flat surface. Attention: you have current in the torch, so avoid any contact with any
metallic part.
NOTE: If the gas, the wire diameter, and the metal used are different from the ones selected in the synergic mode, you
will need to switch to the manual mode to set up the welding unit.

Voltage display (9) :
By pulling the trigger (The LED
torch is on) the voltage will be displayed according to the
parameters selected.
Power adjustment switch (12): 20 positions for the
HEAVYMIG 350-4, 350 GR and 30 for the 450 GR / 450
WS.
Wire speed setting (2): Potentiometer to adjust the
wire speed. The speed can vary from 1 to 24 m/minute.
Note for the HEAVYMIG 350 GR/450 GR/450 WS: It is
possible to select either the potentiometer of the sepa-
rate wire feeder or the generator.
See chapter «wire speed potentiometer» and the sticker
inside the wire feeder
Welding current display (10): indicates the ampe-
rage (LED « A ») or the thickness (11) recommended
according to the power selected (read « test » function
in the chapter « Welding unit settings »).
Note: « NOP » on the display indicates that the welding
current selected is superior to the one recommended
taking into account the parameters (type and diameter
of the wire).
