    WARNING Arc welding and cutting can be dangerous to the user, people working nearby, and the surroundings if the equipment is handled or used incorrectly. Therefore, the equipment must only be used under the strict observance of all relevant safety instructions. In particular, your attention is drawn to the following: Electricity - The welding equipment must be installed according to safety regulations and by a properly trained and qualified person.

This The parameters that can be adjusted are illustrated in reduced current is set to a percentage value of the the figure below: welding current and is variable between 0-100% of the welding current.

A reduction of the positive refinement current may have the effect that dwell time of the tungsten electrode improves.
