*** 4T - Press and release to start, press and release to stop, good for long welds but has more parameters to set and harder to use, not covered in level-1 |

* Parameters set using the middle section. We're using DC (Electrode negative), no pulse, HF-TIG in 2T mode. Back and Forward controls step through the parameters that are relevant to the selected mode |

** Using the chart on top of the welder to pick settings |

** If the chart isn't helping then use the following guidelines. Use all the %age changes that apply to your work, e.g. if you're doing an inside corner on aluminium then apply both +%20 for aluminium and +10% for inside corner for a total of +30% |

** Preflow - Time in seconds, is used to establish coverage of shield gas before the arc is ignited. How much to use will depend a little on what you're doing but 0.5-1.0 seconds is usually reasonable for steel |

** Hot Start - This is an extra very short pulse of current used to help establish the arc, this is IN ADDITION to the base current, so you don't need very much, 5A-20A is normal |
