Functional characteristics Operating concepts 5.2.4 Arc ignition 5.2.4.1 HF ignition Figure 5-1 The arc is started without contact from high-voltage ignition pulses. a) Position the welding torch in welding position over the workpiece (distance between the electrode tip and workpiece should be approx. 2-3mm). b) Press the torch trigger (high voltage ignition pulses ignite the arc). c) Ignition current flows, and the welding process is continued depending on the operating mode selected. End the welding process: Release or press the torch trigger depending on the operating mode selected. 5.2.4.2 Liftarc ignition a) b) c) Figure 5-2 The arc is ignited on contact with the workpiece: a) Carefully place the torch gas nozzle and tungsten electrode tip onto the workpiece and press the torch trigger (liftarc current flowing, regardless of the main current set). b) Incline the torch over the torch gas nozzle to produce a gap of approx. 2-3 mm between the electrode tip and the workpiece. The arc ignites and the welding current is increased, depending on the operating mode set, to the ignition or main current set. c) Lift off the torch and swivel to the normal position. Ending the welding process: Release or press the torch trigger depending on the operating mode selected. 5.2.5 TIG automatic cut-out NOTE The automatic cut-out function will be triggered by two conditions during the welding process: During the ignition phase (ignition fault) • If there is no welding current within 3s after starting the welding. During the welding phase (arc interruption) • If the arc is interrupted for longer than 3s. In both cases, the welding machine ends the ignition or welding process immediately. 24 Item No.: 099-000097-EWM01
Functional characteristics Operating concepts 5.2.6 Function sequences/operating modes The "Select welding parameter" button and the "Welding parameter setting" rotary transducer can be used to control all the parameters for the TIG process: Item Symbol Description 0 Figure 5-3 1 Select welding parameters button This button is used to select the welding parameters depending on the welding process and operating mode used. 2 Welding parameter setting rotary dial Setting all parameters such as ignition, welding, end current, gas pre-flow and gas post-flow times, pulse edges, etc. 5.2.6.1 Explanation of symbols Symbol Meaning Press torch trigger 1 Release torch trigger 1 I t Current Time Gas pre-flows I start t Up tP AMP AMP% t1 t2 ts1 ts2 t Down I end Ignition current Up-slope time Spot time Main current (minimum to maximum current) Secondary current (0% to 100% of AMP) Pulse time Pulse pause time TIG pulses: Slop time from main current (AMP) to secondary current (AMP%) TIG pulses: Slop time from secondary current (AMP%) to main current (AMP) Down-slope time End-crater current Gas post-flows Item No.: 099-000097-EWM01 25
