3.1.1 Selection of MMA/TIG welding
Don`t forget to change polarity of voltage when you go over from one method to another: TIG
welding generally in torch-, MMA welding generally in eletrode holder +, see connection on
page 4 or 5.
3.1.2 Selection of TIG ignition method
Contact ignition:
Spark generation is prevented and arc will be ignited as follows:
1. Touch work piece with an electrode.
2. Start power source with the torch switch.
3. Lift electrode off from work piece in which case arc will be ignited. If arc is not ignited
within 1 s, the ignition must be repeated.
Scratch ignition is not recommended.
Control of ignition spark
Spark power may cause interference with eletronics equipment, which are not properly
protected. If there is interference, use contact ignition.
In order to reduce spark voltage in difficult interference situations, take contact with
authorized Kemppi service work shop.
Spark ignition:
Arc is ignited with high frequency with high voltage spark without touching work piece.
Use of torch switch starts spark generation. Spark strikes from electrode to work piece and arc
is ignited. Welding current is immediately set at set value. Spark distance, shielding gas flow
and current through earthing press have a profound effect on ignition.
If arc is not igniteed within 1s, the ignition must be repeated.
NOTE! Be careful that the torch tip is not touching near skin, clothes or components which are
sensitive for damage, like panels, connectors or switches.
