4.
Select welding settings control mode local control, gun control or remote cont-
rol with selection switch.
5.
Set the welding power and arc lenght with the corresponding potentiometers.
Values are shown in displays.
6.
If necessary, set welding dynamics from the potentiometer.
7.
Start welding and adjust welding power and arc length if needed.
3.4.4. MMA-welding
1.
Select welding process MMA with selection switch.
2.
Select welding settings control mode local control, gun control or remote cont-
rol with selection switch.
3.
Set the welding current with the potentiometer. Values are shown in displays.
4.
If necessary, set welding dynamics from the potentiometer.
5.
Start welding and adjust welding current if needed.
3.5. Storage
The machine must be stored in a clean and dry room. Protect the machine from rain and
keep it away from direct sunshine in places where temperature exceeds +25 °C. Check
that there is free space in front of and behind the machine for air circulation.
3.6. Welding
Welding fumes may cause injury, take care of suffi cient ventilation during weld-
ing!
Never watch the arc without a proper face shield designed for arc welding! Pro-
tect yourself and the surroundings for welding arc and hot spatters!
3.6.1. Choosing welding polarity
You can change the welding polarity for fi ller wire by interchanging the welding and
return curren cable connections.
3.6.2. Earthing
If possible, always fasten the earth clamp of return current cable directly on work piece.
1.
Clean contact surface from paint and rust.
2.
Fasten clamp properly, so that contact surface is as large as possible.
3.
Check that clamp is fastened fi rmly.
3.6.3. Welding operation
See also 3.4. Selecting welding setting. Note! It is recommended to make a test weld
before starting to weld the actual work piece.
Welding operation can be started after the necessary selections and adjustments have
been made. The operation starts when welding wire touches work piece and gun switch
is pressed. Welding arc ignites, shielding gas starts to fl ow and wire feed mechanism
inches welding wire. If necessary adjust wire feed and voltage, or in synergic welding
welding power. Readjust until you have found suitable adjustments.
