The 2-Step - 4-Step changes the function of the gun's
trigger.

2 Step trigger operation turns welding on and off in
direct response to the trigger. Welding process is
performed when the gun's trigger is pulled.

4-Step mode allows to continue welding, when the
gun's trigger is released. To stop welding, the gun's
trigger is pulled again. 4-step mode facilitates to
making long welds.
Note: 4-Step does not work during Spot Welding.

HOT START – value in percentage of nominal value
welding current during arc start current. The control is
used to set the level of the increased current and arc
start current is made easy.

TailOut provides additional heat into the weld without
increasing the arc length or the droplet size. Higher
tailout values improve wetting and may give faster travel
speeds.

Background Current adjusts the overall heat input into
the weld. Changing the background current changes the
shape of the back bead. 100% CO
background current than when welding with blended
shielding gases.
Note: Range depends on the power source.

Peak Current controls the arc length, which also affects
the shape of the root. When using 100% CO
current will be higher than when welding with blended
shielded gases. A longer arc length is required with CO
to reduce spatter.
Note: Range depends on the power source..
