Fronius TPS 3200 MV - Impact of CO2 on the Arc

13 SEP 12
/ Battery Charging Systems / Welding Technology / Solar Electronics
The proportion of CO
2
in the gas is mainly responsible for the shape of the arc and the resulting behavior of it (fusion
penetration, pore creation, etc.).
18% CO
2
• Wider arc range
• Wider fusion penetration
• Little pore creation
5% CO
2
• Narrow arc range
• Deeper, narrower fusion
penetration
• Pore creation possible
