To ensure your battery's longevity,you should: recharge it'at night keep the area where cables are connected to the positive and negative poles clean make sure you are changing the battery fluid regularly have it checked by a mechanic weekly
What is true of a second application of hard wax while the first is setting? Select the correct response: The first application must be with soft wax. The second waxing must be performed on an immediately adjacent area. It cannot be performed on an immediately adjacent area. The second application will make the service more thorough but less expedient.
Why is the travel and work angle important? Because of the jetting force of the electrode end. Because it affects the amount of spatter produced. Because of the force on the welding electrode holder the welding cable has as you move along the weld. They are not important and have little effect on how welds are made.
Electrodes with __ produce welds with the heaviest slag covering the molten weld pool and finished weld bead. cellulose-based fluxes rutile-based fluxes mineral-based fluxes silicon-based fluxes
