protective clothing. Also take the necessary steps to protect any persons within the welding
area.
TIG welding parameter settings
Please remember that the advanced options listed will depend
on a number of factors, If for example you have TIG Pulse, TIG
Mix or Spot mode selected you would see additional options
listed than if you had TIG standard selected. You may also note
that some functions and locked, this is because some settings
will only adjust in manual mode rather than in Synergic mode.
