Lincoln Powertec Separates FAQs
Straight answers to the questions people ask most when choosing and using a separate-feeder three phase MIG welder package.
Why choose a separate machine rather than a compact one?
Choose separates if you weld large workpieces, work at a distance from the power source, use heavy-duty settings or weld all day in a production setting. They generally have a higher current rating and a stronger duty cycle than compact machines.
Compact machines are simpler and more portable, so they suit smaller shops and lighter work. Think about the size of the work, how far you need to reach and how much welding you do.
What is in a ready to weld 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.
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.
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.
