FIELD: welding equipment, namely apparatuses for feeding electrode wire, possibly in different branches of machine engineering in automatic and semiautomatic machines for electric arc welding. SUBSTANCE: one end of flexible guiding duct of tract is stationary joined with receiving union of housing of wire feed mechanism. Helix is arranged inside flexible guiding duct. Said duct is in the form of non-stretchable steel cord-reinforced rubber hose and its second end is joined with tip. Mouthpiece is secured to tip. Helix has such length that its one end rests upon end of receiving union and its other end rests upon end of tip. EFFECT: enhanced reliability of tract for feeding wire at automatic welding processes, lowered labor consumption at operation of tract. 2 dwg
