アーク溶接に使用する溶接用トーチであつて、 電極ワイヤガイドをなす絶縁部材に、少なくと
も１箇所の電極ワイヤへの抵抗加熱用給電部を設
け、通常のアーク溶接用給電部と上記抵抗加熱用
給電部との間、もしくは、抵抗加熱用給電部同士
の間に、アーク溶接用電源とは別の電源から給電
して、その間に配置されている電極ワイヤを抵抗
発熱させることにより電極ワイヤの溶融量を制御
させることを特徴とした溶接用トーチ。[Scope of Claim for Utility Model Registration] A welding torch used for automatic or semi-automatic arc welding using a consumable electrode, which is used for resistance heating of at least one electrode wire in an insulating member forming an electrode wire guide. A power supply section is provided between the normal arc welding power supply section and the above-mentioned resistance heating power supply section, or between the resistance heating power supply sections, by supplying power from a power source different from the arc welding power supply. A welding torch characterized in that the amount of melting of the electrode wire is controlled by generating resistance heat in the electrode wire disposed in the welding torch.
