Straight answers to the questions people ask most when choosing and using a separate-feeder three phase MIG welder package.
A separate MIG welder has the power source and the wire feeder as two units joined by an interconnecting cable. The power source stays on the floor or a trolley, and the feeder sits near the work, carrying the wire spool and the torch.This gives a shorter, lighter torch cable, smoother wire feeding and much more reach around large fabrications than a compact machine that has everything in one case.
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.
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.
