1. Higher working efficiency : CO2 arc has strong penetration ability, deeper welding pool, higher melt efficiency. So, welding speed is faster and productivity is 1-3 times higher than stick welding
2. Lower welding cost : CO2 gas can be easy and cheaply obtained from any
chemical or brewage factory, just 40i??50a?? cost of other welding machines
3. Wider application area: It can be used at any position. The thinnest limit
is 1mm and thickness almost no limit(multi-layer welding). Once thin sheet welding, the speed is faster and distortion is less.
4. Stronger anti-rust ability, lower hydrogen percentage ,better anti-crack
ability.
5. Do not need slag-cleaning after welding, arc is easy control and observation.
Mechanization and automatization are easy realized
