| No. | Welding parameters | Phenomenon | Actions | |
| 1 | Voltage (17.5-19.0)  | 
			High | Splashes | Turn down voltage | 
| Air hole | ||||
| Low | Narrow and high welding seams | Turn up voltage | ||
| Turn up current | ||||
| Affects welding speed | Turn up current | |||
| 2 | Current (85-100)  | 
			Large | Big welding seams | Turn down current | 
| Speed up wire feeding | ||||
| Small | Wide welding seams | Lower wire welding speed | ||
| Incomplete welding | Turn up current | |||
| Welding speed affected | Turn down current | |||
| 3 | Wire feeding speed (2-3cm/s)  | 
			Fast | Huge welding seams | Lower wire feeding speed | 
| Slow | Affects welding speed | Speed up wire feeding | ||
| 4 | Welding wire extrusion length (mm) (8-12)  | 
			Long | Small current | Turn up current | 
| Splashes | Shorten welding wire extrusion | |||
| Short | Large current | Turn down current | ||
| Blocks air faucet | Lengthen welding wire extrusion | |||
| 5 | CO2 (Steel ball at 5 blocks position of barometer)  | 
			Huge | Causes waste | Turn down air feeding | 
| Little | Narrow welding seams | Turn up air feeding | ||
| Air hole | ||||
| 6 | Welding speed (less than 0.5cm/s)  | 
			Fast | Narrow welding seams | Turn up voltage | 
| off and on | Turn up current | |||
| Slow | Huge welding seams | Turn down voltage and current | ||
| Notes | Above actions are only for reference. Specific parameters shall be adjusted according to your actual conditions for the best welding performance.  |
