OPERATION - MMA
Before starting any welding activity ensure that you have suitable eye protection and
protective clothing as, welding rays, spatter, smoke and high temperatures produced in the
process may cause injury to personnel.
Also take the necessary steps to protect any persons within the welding area that may cause injury too.
MMA welding
Select MMA welding mode by pressing the welding
mode icon (circled red), and from the drop down
menu select MMA (other choices are TIG and MIG)
the MMA icon will then be shown as in the image
right (circled red).
When in MMA mode you can select and adjust
welding current and arc force parameters
respectively as described below.
MMA Welding Current Adjustment
MMA welding current adjustment can now be
carried out via the panel control current dial A (as
shown right) rotating the dial either clockwise or
anticlockwise which will increase or decrease the
welding amperage shown on the current display above the dial.
Please Note: Welding current adjustment can be carried out during welding.
Arc Force Current Adjustment
By default the left side of the display will show MMA current (as shown in the image above) and MMA
arc force is shown to the right side of the display, you will also note that a slide bar below these
parameters will also slide left/right when increased or decreased.
By rotating the right control dial clockwise or anticlockwise will increase or decrease the required arc
force current until the desired arc force % is shown on the display.
The example above shows arc force percentage set & will offer up to 50% of the welding current shown.
Hot Start Current Adjustment
With the Evolve 200 the hot start value is related to arc force current. The more arc force you set the
more hot start current you will experience when initialising the welding arc.
VRD indicator
In MMA mode, the VRD indicator will be shown (see image above) which indicate that VRD is active in
MMA mode and the machines output voltage is limited to 14.3V when in idle mode.
Display Area Top Bar - MMA
This multi icon bar shows the operator a
quick view of 'background' settings or
The icons shown will change depending
on MMA chosen settings.
Pressing the icons will allow entry to said
setting.
