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
, 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 pro-
tected. If there is interference, use contact ignition.
