抄録	In the present paper, Tungsten Inert Gas (TIG) arc with Constant Voltage (CV) power source is modeled if arc length changes. And TIG arc with Constant Current (CC) power source is also modeled if arc length changes. The TIG arc is assumed on base material of water-cooled copper. For the CV power source, Maximum temperature of arc plasma and arc current increase with decrease of arc length. For the CC power source, arc voltage changes but maximum temperatures of arc plasma is almost constant in spite of change of arc length. Arc power increases with decrease of arc length for the CV power source. On the other hand, arc power decrease with decrease of arc length for the CC power source. For the CV power source, arc power changes largely if arc length changes. However, for the CC power source, arc power changes little if arc length changes. Heat input from welding power source more stable using a CC power source than a CV power source at TIG welding with a change of arc length.
