<p>System for use in alternately electrode welding and gas/arc welding comprising a current supply cable (11) and a gas conduit in connection with a holder (10) having an associated electrode-carrying head. The holder (10) with associated current conductor member (13) is common for exchangeable first (15) and second (15') electrode-carrying heads. The first head secures the welding electrode (14) for electrode welding. The second head secures the arc electrode (14') for gas/arc welding and forms at the same time a support for a coupling member (31) for coupling to the gas conduit (32) and a control valve (33) for adjusting the supply of gas to and along the arc electrode (14').</p> |
