• Always respect the basic rules of welding.
• Do not block/cover the ventilation holes of the machine.
• Leave the device plugged in after welding to allow proper cooling down.
• Thermal protection: The LED(8) switches on when the unit is on safety mode. The cooling time (forced ventilation) is by cycle of 10 minutes for the
400-4 and 20 minutes (forced ventilation + pump) for the HEAVYMIG 400 GR/500 GR/500 WS depending on the external temperature.
• Ventilation: the fan is only active during the welding and the cooling cycles.
CONTROL PANEL (FIG-4)
Welding mode selection / test:
- 2T: two-stage welding / 4T: four-stage welding.
- SPOT: Spot welding with adjustable spot diameter
- Delay: intermittent welding modes for an optimised 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 settings»

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 manually 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).
« Test » function
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.
«MANUAL » MODE
To set your device, proceed as follows:
- Choose the welding voltage using the 2 power switches according to the thickness to weld.
- Adjust the wire speed using the potentiometer (12).

HEAVYMIG 400-4 / 400 GR / 500 GR / 500 WS
Only in the synergic mode, I twill indicate you the thickness you can weld with the parameters 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.
When in manual this function displays the wire speed setting on display (10).
Voltage display: By pulling the trigger (The LED
9
indicates that your torch is on) the voltage will be displayed
according to the parameters selected.
Power adjustment switch: 20 positions for the HEAVYMIG
12
400-4, 400 GR and 30 for the 500 GR / 500 WS.
Wire speed setting: Potentiometer to adjust the wire speed.
The speed can vary from 1 to 24 m/minute.
Note for the HEAVYMIG 400 GR/500 GR/500 WS: It is pos-
sible to select either the potentiometer of the separate wire
2
feeder or the generator.
