#2002  If a nut is hard to turn, you should:    	2	pull the wrench toward yourself.   	push the wrench with an open hand.   	push the wrench, holding the wrench tightly.   	use a piece of pipe for better leverage.   	   	
#2003  As compared to a 12-point socket wrench, a 6-point socket wrench is better to use because:   	3	it fits more easily on a nut.   	it fits in more positions.   	it is less likely to slip.   	it is less expensive.   	   	
#2004  Chisels having mushroomed heads must:    	3	be used with light pressure.   	be used only if a person is wearing safety glasses.   	have the mushroomed head ground off.   	never be used again.   	   	
#2005  First degree burns:    	3	leave the skin, and possibly the tissue below the skin, white or charred.  	blister, and possibly create breaks in the surface of the skin.  	make the skin red and painful, but with no breaks in its surface.  	blister the skin without creating breaks in its surface.   	   	
#2006  Third degree burns are treated by:    	1	applying cool (not iced) water, covering the area with a sterile, non-fluffy, sterile dressing and calling an ambulance. 	applying cool water until the pain decreases, then use an antiseptic ointment and sterile non-fluffy dressing to cover the burn area. 	apply cool water or, other available cool liquid that can be drunk, then a sterile non-fluffy bandage and seek medical help. 	apply cool water until the pain stops then a sterile non-fluffy bandage.  	   	
#2007  Flash burns should be checked by a professional because:    	4	the welder may not know they have been burned.   	immediate treatment is always required.   	the doctor always knows best.   	of the irritation in the eye the welder can not always tell whether there is something that may cause infection in their eye or not. 	   	
#2008  Forced ventilation is not always required when welding:    	2	austenitic manganese   	steel   	copper   	zinc (galvanized metal)   	   	
#2009  Argon and carbon dioxide can be hazardous:    	1	if they displace the air in a confined space where a welder is working.  	because they can cause fire.   	because they can explode.   	A and B.   	   	
#2010  MSDS information:    	1	specifies how to safely handle hazardous materials.   	specifies possible hazards resulting from use of a product. is usually kept on record in the shop office.  	is obtained from OSHA.   	   	   	
#2011  least, four places has no cracks and is safe to install.    	2	True   	False   	   	   	   	
#2012  The measure of electrical pressure is called:    	2	amperes.   	voltage.   	wattage.   	ohms.   	   	
#2013  The measure of the total number of electrons flowing in an electrical circuit is called:   	1	amperes.   	voltage.   	wattage.   	ohms.   	   	
#2014  The measure of the amount of electrical power in a welding arc is called:   	3	amperes.   	voltage.   	wattage.   	ohms.   	   	
#2015  The purpose of a rectifier is to:    	4	regulate the amount of current flow.   	dampen electrical surges.   	step down high ac voltage shop current to low welding\ voltages.  	convert alternating current to direct current.   	   	
#2016  An electrode holder that heats up when being used may indicate dirty or loose jaws.   	1	True   	False   	   	   	   	
#2017  Operating voltage is the same as:    	1	closed circuit voltage.   	short circuited voltage.   	open circuit voltage.   	constant voltage.   	   	
#2018  Constant current power is also known as:    	2	drooping slope.   	constant potential.   	rising arc voltage.   	continuous output voltage.   	   	
#2019  The weave pattern that works best on a horizontal butt joint is the:   	3	circular pattern.   	"C" pattern.   	"J" pattern.   	"T" pattern.   	   	
#2020  Amperage adjustments at the machine should not be made during welding because current changes during welding usually reduce weld quality.  	2	True   	False   	   	   	   	
#2021  Welding with a short arc length:    	1	reduces penetration   	increases penetration   	produces more spatter   	makes a wider and thinner bead.   	   	
#2022  Welding with a short arc length produces more heat in the weld bead.   	2	True   	False   	   	   	   	
#2023  Slag inclusions on a flat butt joint can happen if the welder:    	4	moves the electrode too fast.   	uses too much amperage.   	moves the electrode too slow.   	uses too short an arc length.   	   	
#2024  The figure 8 weave pattern is used for:    	1	cover passes in the flat and vertical positions.   	cover passes in horizontal and overhead T-joints.   	single pass welds in the flat and vertical positions.   	single pass welds in horizontal and overhead T-joints.   	   	
#2025  If when making a vertical weld bead the puddle starts to sag the welder should:   	1	increase travel speed.   	increase arc length.   	increase the up angle of the rod.   	reduce the up angle of the rod.
