Setup and Documentation
Check the exact machine code and nameplate before installation. Have the electrical supply and protective devices selected according to the operator instructions. Match the process, polarity, consumables and shielding gas to the welding procedure. Maximum output is not a continuous-duty rating; follow the stated duty cycle and allow the required cooling time. The relevant manufacturer document is available in Downloads & Documents.
Frequently Asked Questions
What input power does this model require?
120 V, single-phase, 60 Hz. Follow the machine nameplate and installation instructions.
Is a shielding-gas cylinder included?
The documented package includes a regulator; it does not list a shielding-gas cylinder. Select gas for the wire and procedure.
Is maximum output available continuously?
No. Compare rated amperage, voltage and duty cycle together. Maximum range and rated continuous operation are different specifications.
