GYS UNIMIG 200-4 Mode D'emploi page 13

«MANUAL» MODE (FIG 5) (FIG 6)
To set your device, proceed as follow:
• Choose the welding voltage using the voltage selector
Example: position 1 for 0.8mm metal sheets and position 4 for 3 mm metal sheets.
• Adjust the wire speed with the potentiometer (3).
Advice
The wire speed adjustment is often determinated 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 will crackle and the wire will push back the torch.
«SYNERGIC» MODE (FIG 5) (FIG 6)
This function automatically controls the wire speed. There is no need to set the wire speed manually.
Position the wire speed potentiometer (3) in the middle of the« Optimal synergic » zone.
• Select:
- Wire type (1)
- Wire diameter (2)
- Power mode (4 position switch)
To select the right position in accordance with the thickness of the workpiece, please refer to the "synergic mode" table on the previous page.
From the combination, the UNIMIG determines the optimal wire speed and the device is ready to weld. It is also possible to adjust the wire speed if
necessary by adjusting the potentiometer + or – manually (3).
The last welding configuration is saved in the memory automatically
GAS (for steel welding) :
In synergic mode, UNIMIG determine the welding settings in accordance with the gas used. By default, in steel welding the machine
is set to « Argon + CO2 ».
To change the gas and set the machine to C02 mode or go back to Argon + CO2 mode :
1- Press « Type » for 5 seconds until the panel switches off, then release.
2- After 5 seconds, choose the required setting using the « mode » button.
• Normal (2T) => Argon + CO2 (default setting)
• Delay => CO2 100%
3- Confirm selection by pressing the « Type » button, or waiting 5 seconds.
4- Once confirmed, the machine reverts to the normal operating mode but the gas mode chosen will stay selected, even when the
machine is switched off.
RISK OF BLESSING RELATED TO MOBILE COMPONENTS
The wire feeders contain moving parts that may catch hand, hair, clothes or tools which can lead to injuries! Take extra care.
• Do not place your hand on mobile/pivoting/wire feeding parts of the machine!
• Make sure that all panels remain closed when in use !
Do not wear gloves when setting up the wire and changing the wire reel.
ADVICE & THERMAL PROTECTION
• 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 it to cool.
• Thermal protection: If the machine becomes too hot, the warning light will illuminate and the machine will stop. The cooling time will be a few
minutes; length of time will also depend on the external temperature.
