In the field of fabrication and welding, we sometime come across jobs which are heavy in nature and need auto or semi-auto welding machine to give the required results. But in the absence of such facilities and machineries in a particular situation, engineers have to take daring steps to attempt the same with ordinary transformers and weld manually. While doing such uncommon jobs, a series of precaution measures and supporting facilities are to be thought over before starting and ending the job.
