SMAW
How do you start an arc?
strike the metal like a match
always insure what with cords when welding
always insure that they are not loose or corroded and that they are tight and clean
true or false, SMAW are Relatively inexpensive
TRUE, they are inexpensive
how is heat for welding created?
created by very high resistance of gases in the gap between the electrode and the workpiece
what type of current (SMAW) uses
CC aka constant curent
True or false, SMAW is not Simple to operate
FALSE, SMAW is simple to operate
any loose or corroded connections causes what and what will be lost.
It causes resistances and heat will be lost at these points.
10 - 2,000 amps
TRUE or false, is SMAW capable of welding a high range of materials
TRUE,
were dose the power flow if the polarity reverse
from the power source to the work piece and go's through the electrode head
Explain what a step down transformer does
it converts high voltage, low current electricity into low voltage high current
TRUE or false, does SMAW have large quanitities of fumes produced.
TRUE, weld must mange them too
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
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
True or false, SMAW is not tolerant to outdoor environments.
FALSE, they are tolerant but with with protective enclosures when needed
