Abstract
A small, fractional horsepower, low voltage electric motor with an eccentric weight on its output shaft is attached to the electrode clamp of a hand held welding electrode holder. The oscillating or orbiting motion generated by rotation of the eccentric weight is transmitted through the electrode clamp to the welding rod. Higher quality welds and reduced sticking and burn through result.
Claims5
In combination with a hand held welding electrode holder of the type having a hand grip and an electrode clamp at one end of the hand grip, a mechanism for imparting orbital oscillating motion to a welding electrode comprising:
- a fractional horsepower, low voltage electric motor having an output shaft;
- an eccentric weight connected to and rotating with said output shaft;
- a sealed housing enclosing said motor and said eccentric weight;
- means for securing said housing to the electrode clamp to transmit the oscillating motion generated by rotation of said eccentric weight to the clamp and an electrode clamped therein;
- and
- power supply and control means for said motor.
