A – Shop Welder B – Welder Kit with Air Compressor
Since most structures are fabricated inside a shop, where compressed air or inert gas are readily
available, the first-mentioned welder (see A above) has proved to be an adequate production tool. Where
there is no access to a high pressure air source, such as for outdoor repair jobs, a compressor unit can
be added (see B above). All metal parts of this welder are made of stainless steel because this material
withstands corrosive fumes, resists moisture, and is durable.
The end of the outside barrel is threaded to accommodate various metal tips. Each welder has a
generous length of heavy-duty neoprene air hose, with the electrical cable inside. Accidental stepping on
the hose does not interrupt the airflow.
Hand Welding Tip Speed Tip
Neoprene is used because it resists oil, ozone, caustics, and solvents, and is flexible. A standard 115
volts A.C. outlet is required. A ground wire is provided with the plug and should be used.
The air pressure required:
The welder requires either compressed air or bottled inert gas, both of which Have to be regulated. Each
welder should therefore have its own pressure regulator and gauge that operate on common line
