Troubleshooting welding conductivity
- By Bill Giese
- Jun 17, 2008
- Arc Welding
- Article
When MIG welding, are you experiencing an erratic, sputtering arc; a gradual need to increase voltage at the power source; discoloration of copper cable strands or the liner; increased contact tip burnbacks; or inconsistent weld appearance? If so, your problem could be poor conductivity caused by electrical resistance.

GMAW guns: More than a commodity
- By Bill Giese
- Sep 12, 2006
- Arc Welding
- Article
Many welders think of GMAW guns as just a commodity. However, all of the parts in a GMAW gun have a direct impact on the time it takes to make a weld and its quality.

Elements of success:
- By Mike Sammons and Bill Giese
- Jan 10, 2006
- Arc Welding
- Article
Torches, cables, and cooling are three integral components in gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) equipment, and two cooling methods – air and water – are used in their cooling systems. Although GMAW and GTAW are different processes, the advantages and disadvantages of water- and air-cooled systems are the same. For that reason, you should consider similar factors when choosing a GMAW or GTAW system.
