When buying a machine that will always be in one spot, this may not be a concern. But if the power source will be moved around the shop, or in cases of TIG welding a sign out along the highway, then a portable welder is needed. There are two basic ways to accomplish portability: inverters and engine-driven welders.
Inverters are now available that weigh about 10 pounds and run on115 volt and 230 volt current. Inverters are power converters that allow a machine to be smaller and lighter than conventional machines.
Engine-driven machines are used when a welder has no access to primary power for welding. Engine-driven power sources can be used for in-the-field maintenance, pipe welding, or construction work, and many also have power generating capabilities. |
