Arc stray controlling welding apparatus

A welding apparatus controlling a position of a welding arc, comprising:

• a welding head producing said welding arc in a working zone;
• an electromagnet compensating a magnetic field in said working zone;
• at least four photoelectric elements forming two pairs of photoelectric elements, each of said elements having a viewing area,
• wherein said photoelectric elements are electrically connected to said electromagnet, wherein said viewing areas of said photoelectric elements intersect in a cross-view field;
• wherein when said welding arc is strayed said cross-view field is displaced and a certain potential is supplied from said photoelectric elements to said electromagnet;
• and wherein when said certain potential is supplied to said electromagnet, said electromagnet compensates said magnetic field in said working zone by returning said welding arc into a proper position.

A welding apparatus controlling a position of a welding arc, comprising:

• a welding head producing said welding arc in a working zone;
• an electromagnet compensating a magnetic field in said working zone;
• at least two photoelectric elements, each of said elements having a viewing area of a generally triangular geometric shape,
• wherein said photoelectric elements are electrically connected to said electromagnet, wherein said viewing areas of said photoelectric elements intersect in a cross-view field;
• wherein when said welding arc is strayed said crossview field is displaced and a certain potential is supplied from said photoelectric elements to said electromagnet;
• and wherein when said certain potential is supplied to said electromagnet, said electromagnet compensates said magnetic field in said working zone by returning said welding arc into a proper position.
