... limitations that restrict its use: The welding equipment is more complex, usually more costly, and less portable than SMAW equipment. The process is more difficult to apply in hard-to-reach places because the welding gun is larger than an SMAW holder and must be held close to the joint (within 10...

..., is called a power/control system. It can weld studs with diameters up to 28.5 mm (1.1 in.). Either a single gun or dual guns can be used. Although a light-duty control system can weigh 11.3 kg (25 lb), the system shown in Fig. 4.3 weighs approximately 450 kg (1000 lb) and can be put on a wheeled cart...

An electrostatic charged powder gun that can apply an extremely even and adherent coating of dry powder on metal parts is also used. For simple application, especially when only a portion of the surface...
