Served as both carbon dioxide and mixture gas, and stable arc performance in almost welding current
- Suitable for high speed welding of steel sheets by short circuiting transfer in all positions.
- Flow quantity of shielding gas should be 20?/min in general.
- Keep the distance between tip and base plate metal 6~15mm for 250 Amp. and under or within 15~25mm for more than 250 Amp. of welding current.
