A brake and wire regulator for spools (22 or 40), which supply filler wire to an arc welding gun (10), includes a mounting plate (30 or 62) which is secured to a housing (12a, 12b) for the gun or to a remotely located wire supply housing (38) and a brake arm (32 or 58) having a proximal end pivotally mounted on the mounting plate with the distal end (32f or 58a) of the brake arm extending between the rim plates of the spool. A spring (38 or 64) extending between the mounting plate and the brake arm biases the distal end of the arm against the outer layer of wire on the spool to provide a braking action for the spool to prevent the wire from unspooling when the welding process ceases and impede migration of the outer most layer of wire across the spool.
