US 1 INTRODUCTION This manual describes use of the MA4 control panel, which is installed in the AristoFeed 30--4 and AristoFeed 48--4 wire feed units. For general information on operation, see the wire feed unit and power source operating instructions. 1.1 Control panel 1.2 1 Display 2 Knob for setting the voltage 3 Knob for setting the wire feed speed and welding current 4 Increase (+) or Decrease (--) selected by the function pushbuttons.
US 2 MENUS The control panel uses several different menus. They are the main, measurement and settings menus. 2.1 Main and measurement menus The main menu is always displayed immediately after the machine is started. The menu shows the values which have been set. If the main menu is displayed when welding begins, it switches over automatically to show the measured values (measurement menu). The measured values will be displayed even after welding has been completed.
US Settings Setting range In steps of: Default setting Inductance 0 -- 100 1 70 Gas pre--flow 0,1 -- 25,0 s 0,1 s 0,1 s Slow RunIn start ON or OFF -- ON Burnback time 1 -- 350 ms 10 ms 100 ms Gas post--flow 0.1 -- 20 s 1s 1s Voltage 8 -- 60 V 0.25 V (displayed with one decimal) 12 V Wire feed speed 31 -- 984 In/min 4 In/min 196 In/min *) These functions cannot be changed while welding is in progress.
US 4-- stroke Gas pre--flow Hot start Welding Crater filling Gas post--flow Functions when using 4--stroke control of the welding gun Gas pre--flow starts when the welding gun trigger switch is pressed (1): releasing the trigger switch starts the welding process. Pressing the trigger switch again (3) starts crater filling (if selected) and reduces the welding data to a lower value. Releasing the trigger switch (4) stops welding entirely and starts gas post--flow (if selected).
US Burnback time Burnback time is a delay between the time when the wire starts to decelerate and when the power unit switches off the welding current. Too short a burnback time results in long filler wire stickout, with a risk of the wire being caught in the solidifying weld pool. Too long a burnback time results in a shorter stickout, with increased risk of the arc striking back to the contact tip.
US Explanation of the symbols Active symbol (dark background). Active means that the function which the symbol represents can be activated. New values can only be set when the symbol is active. Inactive symbol (light background). Inactive means that settings for the function which the symbol represents cannot be changed. From the settings menu, pressing an inactive symbol will return the machine to the main menu. A dot in the upper right--hand corner indicates that crater filling is ON.
US 3.4 Settings example This is an example of the settings used for GMA welding. Settings Value Process GMA 2/4--stroke 4--stroke Crater filling ON Crater filling time 1s Inductance 80% Slow RunIn start OFF Burnback time 150 ms Gas pre--flow 0.7 s Gas post--flow 3s Voltage 30 V Wire feed speed 393 In/min Process = GMA welding S Display the main menu for GMA welding by pressing the first function pushbutton. 2/4--stroke = 4-- stroke S Press bi02d1aa to select 4-- stroke.
US Crater filling = 1.0 seconds S Press to turn crater filling ON. S Press until the display shows 1.0 s. Inductance = 80 % S Press until S Press until 80 is shown in the display. is shown in the display. Slow RunIn start = OFF S Press until S Press until 1 is shown in the display. bi02d1aa is shown in the display.
US Burnback time = 150 milliseconds S Press until S Press until 150 is shown in the display. is shown in the display. Gas pre-- flow = 0.7 seconds S Press until is shown in the display. S Press until 0.7 s is shown in the display. Gas post-- flow = 3 seconds S Press until S Press until 3 s is shown in the display. bi02d1aa is shown in the display.

Wire feed speed = 393 In/min S Turn the knob to set the wire feed speed until the display shows 393 In/min. 4 SMA WELDING 4.1 Settings Settings Setting range In steps of Default setting Process GMA, SMA or Arc air--guougin -- MIG/MAG “Hot start”* ON or OFF -- OFF Hot start time 1 -- 30 1 10 Arc force 0 -- 10 0.
US Arc force The arc force “Arc force” is important in determining how the current changes in response to a change in the arc length. A lower value gives a calmer arc with less spatter. Current A higher current produces a wider weld pool, with better penetration into the workpiece. Irrespective of which menu is displayed, the setting value for the current can be changed. The value is only displayed in the main menu. 4.
US Value symbols The value symbols are displayed in the settings menu for each function. 4.3 No arc force Higher arc force Short hot start time Long hot start time Settings example Settings Value Process SMA “Hot start” ON Hot start time 12 Arc force 5 Current 250 Amp Process = SMA welding S Display the main menu for SMA welding by pressing the first function pushbutton. Hot start time = 12 seconds S Press to turn hot starting ON. S Press until 12.0 is shown in the display.
US Arc force = 5 S Press until is shown in the display. S Press until 5.0 is shown in the display. Current = 250 Ampere S Turn the knob for setting the current until the display shows 250 Amp. 5 ARC--AIR GOUGING Arc--air gouging involves the use of a special electrode consisting of a carbon bar with a copper case. An arc is formed between the carbon bar and the workpiece, air is supplied to blow away the melted material, and a seam is formed. 5.
US 5.3 Settings example Setting Value Process Arc--air gouging Current 45 V Process = Arc-- air gouging S Select the process by pressing the first function pushbutton until the display. is shown in Current = 45 V S Turn the knob for setting the current until the display shows 45 V. 6 FAULT CODES Fault codes are used to indicate that a fault has occurred in the equipment. They are shown in the display in the form of a symbol as follows: Fault codes are updated every three seconds.
US Symbols may be steady or flashing, depending on the type of fault. Flashing symbols are highlighted with “o” in the list of fault codes. 6.
