|---|
| Kinking the coil liner | causes restriction on the wire |
| current density | amperage per sq in of the CROSS SECtional area of the ELECTRODE |
| cross- sectional area | cut electrode in two, distance from side to side |
| axil spray transfer | creates high heat, only weld metal thicker than 1/4 in |
| gas metal arc welding | continuous WIRE process |
| CO2 | used as shield, extends process |
| flux | some forms of GMAW use flux |
| spray transfer | 1/8 or thicker, heavy deposit |
| pulsed arc transfer | spatter free, THIN below 1/4 in |
| globular transfer | low volt, low amp lots of splatter |
| short circuiting arc transfer | NO metal transfer across welding arc |
| short circuit arc transfer | used on thick and thin metal, uses wide range of gases |
| reverse | polarity for GMAW |
| alternating current | causes BURN rate to be UNEQUAL |
| constant voltage machines | instant, flawless arc start |
| GMAW amount of CURRENT | decided by SPEED of wire FEED |
| wire feed | does NOT control voltage |
| purpose of gas shield | COOL while welding block contaminants |
| contaminants | trash |
| Cause wire stick out to increase | decrease voltage |
| instant arc starting | wire does NOT stick |
| pull wire feeder | used only with soft wires like aluminum |
