China Suppliers Factory Wide Voltage Gasless Welding Machine 220V/380V with 36V Control and 8 Inverters
The welder provides the ability to MIG, LiftTIG or ARC(Stick) weld all from a single, high-powered, self-contained unit. Inverter Technology provides the capability of welding thin or heavy gauge steel with precision and ease. For additional versatility and aluminum welding capability.
The Welder has dual current capability and requires a dedicated, 50 Amp. 60HZ grounded outlet protected by a circuit breaker. If using an extension cord, use a minimum 6 AWG cord for up to 25 feet.
The rated Duty Cycle refers to the amount of welding that can be done within a period of time. The 270K has a Duty Cycle of 60% at 270 Amps. It is easiest to look at your welding time in blocks of 10 Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 270 Amps with a 60% Duty Cycle, within a 10-minute block of time, you can weld for 6 minutes, 4 minutes for cooling the Welder. If the Duty Cycle is exceeded, the Welder will automatically shut off; however, the fan will continue running to cool the internal components. When a safe temperature has been reached, the Welder will automatically switch the Welder output back on. To increase the Duty Cycle, you can turn down the Voltage Output control.
A Shielding Gas Bottle is NOT INCLUDED with your KEYGREE MIG-270K but necessary when welding with Solid Wire. It can be bought at most local Welding Supply Stores. It recommends the use of 75% Argon/25% CO2 for shielding gas when MIG welding Steel, 100% Argon for Aluminum, and Tri-Mix (90% He/7.5% Ar/2.5% CO2) for Stainless Steel.
- All movements adopt the latest and mature IGBT full-bridge inverter technology.
- IGBT inverter technology, less welding spatter and beautiful welding seams.
- Complete undervoltage, overvoltage and current protection, safe and reliable.
- Accurate digital display of current and voltage preset, easy and intuitive operation.
- High pressure and slow wire feeding to start the arc, the arc will not burst the wire, and the arc will be closed to remove small balls.
- Constant voltage output characteristics, CO2 welding, one machine for multiple purposes.
- With self-locking/non-self-locking mode, greatly reducing operating intensity.
- Optional extended control cable, suitable for welding operations in narrow and high locations.
- Three-proof design for key parts, suitable for various harsh environments, with stable and reliable operation.
