EN2.8.3 Arc length trimmer in automatic modeThe arc length/weld shape/voltage trimmer adjusts the length of the arc, either shorter orlonger, and affects the welding temperature. A shorter arc is colder and a longer one hotter.The arc length trimmer also affects the arc’s welding properties and influences weld spatterwith different combinations of filler wire diameters and shielding gases. The trimmer range is-9...0...9: negative values shorten and positive values lengthen the arc. The trimmer is preset at0 which is, in most cases, a suitable basic setting.If the weld is too convex, the arc is too short or cold. Then adjust the arc longer or hotter byturning the control clockwise.If, on the other hand, you want to weld with a colder arc to prevent for example the parentmaterial from burning through, adjust the arc shorter by turning the control counterclockwise. You can also adjust the welding power, if needed.When adjusting the arc length, the cross sectional weld joint graphic on the machines displaychanges correspondingly to either a more concave, flat or convex weld result.NOTE! When welding for the first time, we recommend that you set the arc length trimmer to 0.2.8.4 Display in manual mode1.2.3.1. Operating mode2. Wire feed graphic3. Welding values: wire feed speed, welding voltage and welding currentThe selected 'Manual' operating mode is confirmed on the display. During welding, the wirefeed speed graphic displays the wire’s speed. Wire feed speed is the only welding parameteralways visible on the display. When adjusting welding voltage, the display shows the set valuefor the voltage, and only during welding does the display show the actual value. Weldingcurrent is visible on the display only during welding. Values for actual welding voltage andwelding current remain on the display after welding, until welding is restarted or settings arechanged.13MinarcMig Evo 200 / © Kemppi Oy / 1110
