SETTINGS PANEL (FIG 5)
10 - Welding mode selection
• NORMAL (2T): standard two-stage welding
• NORMAL (4T): standard four-stage welding
• DELAY: intermittent welding modes for optimised operating procedure.
• SPOT : Spot welding with adjustable spot diameter
11 - Wire speed selector
Wire speed regulator.
The speed varies from 1 to 15 m/minute.
12 - SPOT potentiometer
«MANUAL» MODE (FIG 5) (FIG 6)
To set your device, proceed as follow:
• Choose the welding voltage using the voltage selector
Example for the UNIMIG 250-4: 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 185-2S 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.
UNIMIG
13 - Manual Mode
In manual mode, the wire speed is determinated by the user by adjus-
ting the potentiometer (11).
14 - Synergic Mode
Position the potentiometer (11) in the middle of the « OPTIMAL SYNER-
GIC » zone
In this mode, the device determines the optimum wire speed according
to 3 parameters:
• Voltage
• Wire diameter
• The power mode
The wire speed is adjustable + / -.
