The tool includes an electrode holder, a hand grip and a feed cable connected to the positive pole of a DC generating set and a compressed air source. The electrode holder has a fixed arm rigidly connected to the hand grip and a movable arm pivotable around on axle pin and tensioned so that it pivots automatically in the direction towards the fixed arm through the effect of an inner spring. The movable arm forms a clamp grip in conjunction with a blower head (16) fitted by a central screw at the outer end of the fixed arm. A screw centres the blower head in a conical set at of electrical conductive material connected to the cable. The seat encompasses a channel for supply of compressed air from the cable via the hand grip. |
