Straight answers to the questions people ask most when choosing and using a separate-feeder three phase MIG welder package.
A package normally brings together the power source, wire feeder, torch, interconnecting cable and work return lead, so the main parts are matched. Some include a trolley or a cooling unit. The contents vary, so check the product listing.You will still need shielding gas and a regulator, welding wire to suit the material, and your protective equipment. Keep spare consumables such as contact tips and nozzles.
An air-cooled torch is lighter and needs nothing extra, and it suits moderate current and intermittent welding. A water-cooled torch needs a cooling unit with a pump and coolant, but it carries higher current for longer and stays more comfortable.Choose water-cooled for heavy, continuous or high-current work. Keep the coolant topped up with the recommended type and never run the torch without flow.
Longer cables give more reach but can affect performance if they exceed what the system is designed for. The maker will state the lengths that are permitted, so use only what the manual allows.Avoid coiling spare cable tightly. Keep connectors clean and fully tightened, and route the cable so it is not crushed, kinked or pulled over sharp edges.
These machines are normally three phase and need a supply of the voltage on the data plate, usually 400 volts in the UK, with a correctly rated plug, cable and protective devices.Have a competent electrician install or check the supply. If you want to use a generator, check the manufacturer's advice first, because an undersized or poor quality supply can cause faults.
