Two-channel device for two-frequency arc welding

A method of igniting an arc discharge and welding thereby;

• said method comprising steps of:
• a. providing a two-channel device for igniting an arc discharge and welding thereby;
• said two-channel device comprising:
• i. a first channel further comprising:
• 1. a power supply further comprising a power transformer;
• and
• 2. a controller of said power transformer;
• ii. a second channel further comprising:
• 1. a high-frequency generator and
• 2. a resonant circuit connected in series to said high-frequency generator;
• iii. said first channel comprises a timer configured for switching on said power transformer after a predetermined delay;
• said second channel comprises a current meter configured for measuring a high-frequency current;
• said current meter is connected to said timer and triggers said timer;
• ii. output terminals connectable to an electrode and a welding stand;
• said first and second channels are connectable to said output terminals;
• b. placing articles to be welded onto said welding stand;
• c. connecting said electrode and welding stand to said output terminals;
• d. contacting said electrode with at least one of said articles to be welded;
• e. applying a high-frequency voltage generated by said high-frequency generator to said electrode;
• f. after a predetermined delay applying a welding voltage from said power transformer to said electrode;
