Abstract
Control apparatus for a gas-shielded welding arrangement which includes a monitor for logging welding parameters, a gas surge tank, the volume of which is adjustable to take account of the pressure of a gas-supply source, and a lockable device which prevents unauthorised access to a pressure regulator on the surge tank.
Claims11
Control apparatus for a gas-shielded, arc welding arrangement which includes a welding gun, an electrode wire feed mechanism, a shielding gas source, a first pressure regulator on the gas source, and a controller for controlling the supply of shielding gas from the shielding gas source to the welding gun, and wherein, when welding takes place, the feed mechanism feeds electrode wire to the welding gun and the controller delivers shielding gas from the shielding gas source to a welding location, and generates data relating to the function of the welding arrangement.
A surge tank for supplying shielding gas to a welding gun, the surge tank including two interengageable container parts which bound an absolute enclosed volume, a pressure regulator connected to the inlet and a lockable device which must be unlocked to allow the pressure regulator to be accessed and adjusted.
A surge tank for supplying shielding gas to a welding gun, the surge tank including two interengageable container parts which bound an absolute enclosed volume, a pressure regulator connected to the inlet and at least one component, located inside the volume, to reduce the size of the volume.
A welding arrangement which includes a welding gun, an electrode wire feed mechanism, a shielding gas source, a pressure regulator on the gas source, and a controller for controlling the supply of shielding gas from the shielding gas source to the welding gun, and wherein the controller includes a surge tank between the shielding gas source and the welding gun, and the surge tank has an absolute volume the size of which is dependent on the setting of the pressure regulator.
