«MANUAL» MODE
To set your device, proceed as follows:
- Choose the welding voltage using the 2 power switches (2& 7 positions)
Example:
For welding Steel - 1 mm
- Set the top switch to "A"
- Set the bottom switch to "1"
For welding Steel - 10 mm
- Set the top switch to "B"
- Set the bottom switch to "7"
- Adjust the wire speed with the potentiometer .
Advice
The wire speed adjustment is often determined by « the noise »: the arc must be stable and emit low
crackling.
If the speed is too low, the arc will not be continuous.
If the speed is too high, the arc crackles and the wire will push back the torch.
« SYNERGIC » MODE
This function automatically controls the wire speed. There is no need to set the wire speed manually.
Position the wire speed potentiometer in the middle of the« Optimal synergic » zone.
-
Select:
Wire type
Wire diameter
Power mode (2 switches, 2 & 7 positions)
To select the right position in accordance with the thickness of the part to weld, please refer to
the “synergic mode” table on the previous page.
From the settings chosen, the Trimig 385-4S determines the optimum wire speed and the device is ready to
weld.
It is also possible to adjust the wire speed if necessary by adjusting potenti or – manually .
The last welding configuration is saved in the memory automatically (wire diameter, wire type, mode).
ADVICE & THERMAL PROTECTION
•
The Trimig 385-4S should not be lifted by its handles, torch support, or the top of the machine. When lifting
the Trimig,
ensure the weight is fully supported at the bottom of the machine
. There must be no gas
bottle connected during this operation.
•
Always respect the basic rules of welding.
•
Do not block/cover the ventilation holes of the machine.
•
Leave the device plugged after welding to allow it to cool.
•
Thermal protection: If the machine becomes too hot, the warning light will illuminate and the machine will
stop. Cooling will take a few minutes, the length of time will also depend on the external temperature.
DUTY CYCLE & WELDING ENVIRONMENT IN USE
•
The welding unit describes an output characteristic of "constant current" type. The duty cycles following the
standard EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below:
X / 60974-1 @ 40°C (T cycle = 10 min) I max 60% (T cycle = 10 min)
100% (T cycle = 10 min)
Trimig 385-4S / Duogys 390-4S 25% @ 370 A 280 A 210 A
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 environment, it can be difficult to ensure electromagnetic compatibility, due to conducted
disturbances as well as radiation.
