Lincoln Powertec Separates FAQs
Straight answers to the questions people ask most when choosing and using a separate-feeder three phase MIG welder package.
What does a separate MIG welder mean?
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.
Should I choose air-cooled or water-cooled?
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.
How long can the interconnecting cable be?
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.
What electrical supply does it need?
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.
