Detailed Information
IGBT Inverter Gas Shielded Welding Machine
GMAW welding machine can perform melting electrode welding without gas protection. mainly uses the positive and negative polarity exchange,at the same time the use of FLUX core welding wire, and can use co2,as well as manual welding ,simple scratch argon arc welding function.
The rated Duty cycle refers to the amount of welding that can be done within an amount of time. It is easiest to look at your welding time in blocks of 10Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 155 Amps with a 60% Duty Cycle, within a 10 Minute block of time you can weld for 6 Minutes with 4 Minutes of cooling for the welder.
Operating methods
1
After correct installation, turn on the power switch and push the power switch in the "ON"position. Then, the power indicator light will be on and the fan inside the welder will start rotating.
2
According to the actual situation of use, the adapter is connected to the corresponding position,and the ground wire is firmly connected to the workpiece.
3
According to the diameter of the welding wire, select the diameter of the contact tip of the welding gun.
4
According to the thickness and process ofthe workpiece to be welded,cooperate with the"voltage adjustment" knob and "current adjustment" knob to the corresponding position.
5
"Auto" mode can be selected,at this time it is a unified adjustment, only the current needs to be adjusted, and the voltage is automatically matched.
6
In the "manual" mode,the current and voltage need to be adjusted separately,and the parameters can be manually matched to achieve a good welding process.
Main Features

Frequently Asked Questions (FAQ)
What is the advantage of IGBT full-bridge inverter technology in these welders?
IGBT inverter technology allows for a more compact and lightweight design while providing stable output, less welding spatter, higher efficiency, and better control over the welding arc.
Can I use this welding machine without gas protection?
Yes, the GMAW welding machine can perform gasless welding by using flux-cored welding wire and adjusting the positive and negative polarity exchanges.
How do I interpret the rated duty cycle?
The duty cycle is calculated in 10-minute blocks. For example, a 60% duty cycle means you can weld continuously for 6 minutes at the rated current, followed by 4 minutes of cooling time.
What is the difference between "Auto" mode and "Manual" mode?
In "Auto" mode, the voltage is automatically matched based on the current setting. In "Manual" mode, you can adjust the current and voltage separately to fine-tune the welding process parameters.
What are the environmental requirements for installing the welder?
The machine should be used in temperatures between -10℃ and +40℃. Ensure the air inlets and outlets are not blocked, avoid direct sunlight exposure, and take dust-prevention precautions.
