Sherman Workshop MIG 200M User Manual page 9

8.2.2 Setting the welding parameters and braze
1. Turn on the power supply connector on the rear of the device.
2. The switch method of welding (5) to position MIG / MAG welding.
3. The rotary knob (7) to the appropriate welding voltage.
4. knob (6) Set the wire feed speed.
5. knob (8) adjust the inductance (see point 6).
8.2.3 arc Initiation
1. Bring the holder parts to be welded, so that the distance between the nozzle and the welded parts was approx. 10 mm.
2. Press the button on the torch and start welding. Releasing the button will complete the welding process.
9. Before calling service,
In the event of malfunction of the unit, before sending welding for service, check the list of basic failures and try to remove them yourself.
Repair work may only be carried out after removing the plug from the wall socket.
Attention! The device is not sealed, and the user can remove the cover of the welding device in order to remove minor breakdowns.
symptoms

No power supply
The device has been overheated.
The fan was blocked folded cover
Inadequate or poor quality materials or
consumables,
Shielding gas flows from the wrong intensity.
Inductance wrong setting.
Wrong polarity of welding cables
Humid electrode.
Welder is supplied from the generator or by a long
extension cord diameter is too small cable
Remove the cover, check and correct the connection of
all electrical plugs inside the device
Set the correct pressure
Wear an appropriate guide roll
Replace contact tip
Replace contact tip
Clean the roll groove or replace the roll
Attach the wire spool correctly
To improve mass contact terminal
replace switch
Check the condition of the electrical connections of the
handle, check that the pins in the socket are not broken
or jam
Reduce the welding voltage
Increase the speed of wire feed
Increase welding voltage
Reduce the wire feed speed
Check the fuses on the network connection
Wait a few minutes until the LED goes out and
continue welding.
Straighten fan cover
Replace consumables. Change the welding wire or the
gas cylinder for materials suitable or higher quality
Check the gas hose, improve the connection hose with
fittings and quick status check Cylinder regulator, adjust
the inductance.
Connect the correct welding wires
replace electrode
Connect directly to the mains
