4. Select welding settings control mode local control, gun control or remote control 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 control 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 sufficient ventilation during welding!
Never watch the arc without a proper face shield designed for arc welding! Protect
yourself and the surroundings for welding arc and hot spatters!
3.6.1. Choosing welding polarity
You can change the welding polarity for filler 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 firmly.
3.6.3. Welding operation
See also 3.4. Selecting and adjusting welding settings. 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 flow 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.
