Mastertig MLs™ 300 aDCD / 0743 – 1© keMppi oyHF/contact ignition in TIG welding (water fill)TIG arc can be started either with high frequency (HF) or without (contact ignition). HF ignitionis chosen by pressing the HF CONTACT button to turn on the HF light.If you use water-cooled torch you can fill it with water by pressing the HF CONTACT button formore than 2 seconds. The display reads ’COOLER’.Welding torch switch 2 sequence functionGas flow starts when the torch switch is pressed. Welding starts, and the current will rise to the HotStart current within the up-slope time, remain at that level for the set time (H2t) and then changeto the welding current. The Hot Start function can be disabled and green panel light switches offwhen the Hot Start current is adjusted to 100 %. The current will then rise directly to the weldingcurrent level within the up-slope time. Release the torch switch, and the current starts to drop,and after the selected down-slope time the arc is broken. After this, the shield gas will flow forthe time selected.Welding torch switch 4 sequence functionGas flow starts when the torch switch is pressed. Release the torch switch. The ignition sparkignites the arc, and the current will rise to the Hot Start current within the up-slope time. You canswitch from Hot Start current to welding current with a short press of the torch switch. You candisable the Hot Start function by adjusting the Hot Start current to zero per cent. The current willthen rise directly to the welding current level within the up-slope time.Press the torch switch down, and the welding continues. Release the torch switch, and the currentstarts to drop and after the selected down-slope time the arc is broken. After this, the shield gaswill flow for the time selected.Remote controlIf you choose to adjust the welding current with a remote control unit you need to connect the unitand select the remote control selection button. The PANEL light switches off, and you can selectthe unit (R10, foot pedal control R11F, or torch control). The foot pedal control works only in 2Tmode. Hold the remote control selection button (LO/HI) down to adjust the limits of the remotecontrol’s adjustment range.Adjustment of parametersTo select TIG welding parameters you only need to use two buttons: arrow-left and arrow-right.Red panel light shows parameter you have chosen. Adjustment is done with the potentiometer.When pressing the RETURN button, adjustment of parameters goes straight to welding current.The display shows automatically numeric values and the units of the parameters. When you adjustthe parameters, you can see the value on the numerical display. After 10 seconds, the display willreturn to the welding current.
