Abstract
The invention contemplates an adapter for easily converting existing gas metal arc welding apparatus to serve the relatively elevated gas-flow requirements of a gas-constricted arc nozzle. The adapter makes it possible to utilize a shop-air or other high-capacity source of pressurized gas, in substitution for a conventional gas cylinder, and in making the substitution the existing solenoid valve and its controls remain without change except that the solenoid valve becomes the control, for pilot operation of a main valve forming part of the adapter.
