gas time elapses as set.
HF or Contact ignition selection
The TIG arc can be established with or without an HF pulse. If the HF lamp is not
illuminated the arc can be established by lightly contacting the tungsten electrode to the
work piece. Press the torch trigger and then quickly rock back onto the torch ceramic, so
lifting the contact of the tungsten electrode from the work piece (2T function); the arc
is established simultaneously and effectively. For HF ignition, press the HF button so
that the lamp is on (item 6). Press the TIG torch trigger and hold or release, depending
on whether 2T/4T is selected. The shielding gas flows and the HF (High Frequency arc)
ignites the welding arc.
Setting parameters
Welding parameters (items 2) are selected via the arrows selection keys (items 3).
Setting adjustments are made via the encoder potentiometer (item 8). The numerical and
parameter values will be automatically displayed on screen at parameter selection and
adjustment. After 3 seconds, the screen will return to welding current set value.
4. SERVICE
All electro mechanical devices require routine service maintenance depending on usage.
We recommend that you schedule a service inspection of your welding machine every six
months if used regularly. An authorised Kemppi service agent will inspect and clean your
machine, ensuring that all power connections are tight and secure. Power connections
can become loose and oxidised with frequent and high changes in temperature. This type
of routine maintenance will prevent unnecessary malfunctions.
Disconnect the machine from the mains before handling the electrical cables.
4.1. Daily maintenance
• Check the welding torch electrode. Sharpen or replace damaged electrodes.
• Check the tightness of the grounding cable connections.
• Check the condition of the power and welding cables and replace any that are
damaged.
