Miller Electric, has grown from a one-man operation selling products in northeastern Wisconsin to what is today one of the world's largest manufacturers of arc welding and cutting equipment. [1]
The long wait times for custom-made equipment from established craftsmen such as his future mentor, Adolph Bayers, inspired Klapper to start making bits. [5] In 1968, Klapper became a full-time bit and spur maker due to the high demand for his work. He started his business near Childress, Texas, before eventually relocating to Pampa, Texas. [5]

The same equipment can be used for oxyacetylene blowtorches and welding torches, by exchanging the part of the torch in front of the torch valves. For a basic oxy-acetylene rig, the cutting speed in light steel section will usually be nearly twice as fast as a petrol -driven cut-off grinder.
Wet welding with a stick electrode is done with similar equipment to that used for dry welding, but the electrode holders are designed for water cooling and are more heavily insulated. They will overheat if used out of the water. A constant current welding machine is used for manual metal arc welding.
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
