Gas Connection - GYS PROMIG 400-4S Manual Del Usuario

GAS CONNECTION

Connect the manometer (flowmeter) to the gas bottle if needed, then connect the gos hose to the gas connector. To avoid gas leak,
use collars supplied in the accessories box. Make sure the gas bottle hold in place respecting chain fastening cf. FIG-IV-1.
Maximum gas pressure : 0.5 MPa (5 bars).
LIQUID COOLING (PROMIG 400 DV WS AND 400 G DV WS)
Connect the red and blue wire of the connecting harness from the generator.
Fill the tank up to its maximum. The cooling liquid recommended by GYS (ref. 052246), must be used. The use of any other cooling liquid, and
especially the standard automobile liquid, can lead by electrolysis effect, to the accumulation of dumps in the cooling system, damaging it and even
more by blocking the circuit.
Any damage caused to the machine by the use of another cooling liquid will not be taken under warranty.
The PROMIG 400 DV WS and 400 G DV WS can be operated with an air-cooled torch or a water-cooled torch.
For use with an air-cooled torch, do not activate the on/off switch on the cooling unit.
For use with a water-cooled torch, activate the on/off switch on the cooling unit.
PROMIG 400 DV WS and 400 G DV WS : NEVER USE YOUR UNIT WITHOUT COOLING LIQUID
when the pump is working. Ensure liquid is at least minimum level (gauge at back of machine)
Failure to adhere to this may result in irreparable damage to the cooling system, and machine.
• 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.

- SPOT : spot function, with adjustment of the spot diameter
Wire speed adjustment (4) Adjustment wire speed potentiometer.
The speed varies from 1 to 20m/minute.
SPOT adjusting potentiometer (5) : To adjust the welding time of a
point, the size of the point and the time between each point.
Manual mode (1)

Synergic mode (3)
Position the potentiometer (4) in the centre of the zone «OPTIMAL
SYNERGIC »
In this mode, the device determines the optimal wire speed accor-
ding to 3 parameters:
- Voltage
- Wire diameter
- Wire type
It is still possible to adjust the wire speed +/- with the potentiome-
ter (4).
