Manual metal arc
(MMA) welding
CAUTION!
Danger of injury and damage from electric shock.
When the power switch is switched to position ON, the rod electrode in the electrode
holder is live.
▶ Ensure that the rod electrode is not touching any people or electrically conductive or
grounded parts (housing, etc.)
1 Set the Job 6 for the MMA process and the front panel screens will show the electrode welding
2 Once the “Process” is selected the electrode welding is ready
The welding voltage is applied to the welding socket with a three second time lag.
If the MMA welding process is selected, a cooling unit, if present, is automatically
deactivated. It is not possible to turn it on.
IMPORTANT! Under certain circumstances, it may not be possible to change welding
parameters that have been set on the control panel of a system component - such as
remote control or wirefeeder - on the control panel of the power source.
3 Press the “Parameter selection (FNC)” button from the front panel to select the amperage parameter.
4 Use the selection knob from the left side of the panel to set the desired amperage.
The amperage value is displayed on the left-hand digital display.
All parameter set values that are set using the selection dial are saved until their
next alteration. This applies even if the power source is switched off and on again.
5 Initiate welding process
To display the actual welding current during welding:
- Press the “Parameter selection (FNC)” button from the front panel to select the welding current
(A) parameter
- The actual welding current is shown on the digital display during welding.
Corrections during
welding
To obtain the best possible welding results, the arc-force dynamic parameter will sometimes
need to be adjusted.
The welding parameter value is shown in the digital display located above it.
To influence the short-circuiting dynamic at the instant of droplet transfer:
- = soft, low-spatter arc
0 = neutral arc
+ = hard, stable arc
