Abstract
The invention relates to a process for striking an arc and to a torch employing said process. An electronic ignitor located at a maximum distance of 8 meters from the torch has a high-voltage conductor which leads to a spark gap adjacent the part to be welded. The high-voltage circuit is closed in the region of the zone to be ionized between the welding electrode and the part.
