1
Comparing with other welding machines, CO2/MAG arc welding machine has the
following features
：
◆
Higher working efficiency : CO
2
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
◆ Lower welding cost : CO
2
gas can be easy and cheaply obtained from any
chemical or brewage factory, just 40 ～ 50 ℅ cost of other welding machines
◆
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.
◆
Stronger anti-rust ability, lower hydrogen percentage ,better anti-crack
ability.
Do not
◆
need slag-cleaning after welding, arc is easy control and observation.
Mechanization and automatization are easy realized.
At present, CO
2
gas welding machine is mainly used for dark metal welding, such as
low carbon steel alloy , low alloy steel and so on, it also can be used for stainless
steel welding with mixed gas or cored wire.
