    3. TIG or MMA

    4. Function of torch Two-stroke Welding is started by pressing down the torch trigger. Welding will continue until the trigger is released, after which slope down will begin. The machine can be reactivated during slope-down and gas post-flow. Four-stroke Welding is started by pressing down the torch trigger. Welding will continue after the trigger is released. The next press on the trigger activates slope down and interrupts the welding proces. In TIG welding it is possible to choose between two different ignition methods.

    5. HF or LIFTIG? HF-ignition In this case of contact free ignition the Tungsten electrode does not touch the workpiece, but ignites by means of a high frequency spark (HF), when the torch trigger is activated. LIFTIG-ignition The Tungsten electrode must touch the workpiece in order to establish the arc. The torch trigger is activated, the Tungsten electrode is lifted away from the workpiece, and the arc is established.

    6. AC/DC welding current Choice of voltage Generally speaking, an AC/DC welding machine, (double current machine) welds all materials. AC welding is chosen for welding in all materials containing aluminium. The principle is that the positive current removes the oxide membrane on the surface and the negative current gives penetration into the material. DC welding is used for all other materials such as stainless, copper and common steel.

    7. With or without pulse It is possible to choose pulse welding in DC and AC mode DC welding without pulse is chosen, for which reason pulse parameters cannot be chosen. DC pulse welding is chosen. AC welding without pulse is chosen, for which reason pulse parameters cannot be chosen. AC pulse welding is chosen.

    8. Operation Alternatives for setting the welding current: Internal adjustment The control knob is used for setting the welding current. Adjustment of Dialog The current is set with the knob on the Dialog TIG torch. The maximum welding current is set with the knob on the control panel. External adjustment Current and parameter are set via a foot pedal.

    9. AC time balance +/- time balance In TIG welding with alternating current this function sets the cleaning effect. This function is a balance between the positive and the negative half period based on time, variable between 40% and 80%. The percentage is the share of the negative half period of a full period. The balance will ensure a suitable cleaning zone around the weld pool.

    10. Adjustment of pulse time Pulse time States the period of time in which pulse current is used for welding. Pulse current is identical with the set welding current. Time can be set between 0.1 and 2 secs.

    11. Base current Base current Base current is set as a percentage value between 1 and 99% of the set welding current, however, not under A.

    12. Pause time Pause time Pause time states the period of time in which base current is used for welding. Time can be set between 0.1 and 2 secs.

    13. Gas post-flow Gas post-flow The time from extinction of the arc until interruption of the gas supply. Used to protect the weld pool and the Tungsten electrode and to cool the torch. Time can be set between 1 and 30 secs.

    14. Slope-down time Slope-down time When welding is interruped with the torch, the machine enters slope-down. In this phase the current is lowered from the set welding current to the stop Amp. The duration of this phase is called slope-down time. Time can be set between 0 and 10 secs.

    15. Adjustment of current Adjustment of welding current Welding current is adjusted via the control knob, unless minor remote control is chosen. When the machine is not in use, the set current is shown in the display, whereas during welding the actual welding current is shown. In connection with pulse welding the display will show pulse current and base current respectively. When shifts between welding current and base current become faster than it is possible to perceive with the eye, the display will show the average value.

    16. Connection for gas Quick release fitting for protection gas Connection of the quick release fitting on Migatronics air-cooled TIG welding hoses. The quick release fitting is a press-in coupling which is released by a small press with two fingers.

    17. Connection for remote control Multi plug for foot pedal Via the 7-poled Pilot plug on the front it is possible to connect foot pedal for start and stop of welding and adjustment of welding current.

    18. Current connection + and - pole for welding current Connection to both TIG and MMA welding with a 25 mm2 dinse plug. Polarity for TIG welding is minus polarity on the torch. In AC welding also the minus connection for the torch is used. In MMA welding it is possible to use AC or DC either with plus or minus pole on the electrode (follow suppliers instructions).

    19. Mains voltage error Mains voltage error The LED lights red in case of over voltage or under voltage. The LED is lit for five seconds after rectifying the error to ensure that also short errors are registered by the user. The machine is designed to stand mains voltage variations of +/- 10%.

    20. Overheating Overheating The LED lights yellow if welding is interrupted by too high temperature in the machine. The machine will reconnect automatically after a short cooling period.

    21. Voltage indicator Welding voltage The LED lights for safety reasons if the electrode or the TIG torch is under voltage.

    22. Display Green digital display The display shows the set welding current before welding and the actual welding current during the welding process. Actual welding current may vary a little compared to the pre-set welding current, which is mainly caused by type of electrode and length of the arc.
