SMAW Welding circuit/current
welding advantages/disadvantages
100

How do you start an arc?

strike the metal like a match

100

always insure what with cords when welding 

always insure that they are not loose or corroded and that they are tight and clean

100

true or false, SMAW are Relatively inexpensive 

TRUE, they are inexpensive 

200

how is heat for welding created? 

created by very high resistance of gases in the gap between the electrode and the workpiece 

200

what type of current (SMAW) uses 

CC aka constant curent

200

True or false, SMAW is not Simple to operate 

FALSE, SMAW is simple to operate 

300

any loose or corroded connections causes what and what will be lost. 

It causes resistances and heat will be lost at these points.

300
from ___ to ___ dose an arc form across the gap between the workpiece and the electrode

10 - 2,000 amps

300

TRUE or false, is SMAW capable of welding a high range of materials

TRUE, 

400

were dose the power flow if the polarity reverse

from the power source to the work piece and go's through the electrode head

400

Explain what a step down transformer does

it converts high voltage, low current electricity into low voltage high current

400

TRUE or false, does SMAW have large quanitities of fumes produced. 

TRUE, weld must mange them too

500

what voltage settings do you set for 1/8th rod vertical 7018

HAHAH LOSER WE DONT USE VOLTAGE AND NOW WE"LL PURGE YOU. GET IT YOU DONT PURGE EITHER,

oh yeah we use amps and 105-125 for 1/8th

500

what are the 5 main components of a welding circuit? 

1 power source, mains power supply, 3 work return lead, 4 electrode lead, 5 the holder

500

True or false, SMAW is not tolerant to outdoor environments. 

FALSE, they are tolerant but with with protective enclosures when needed
