The TECFEED 350i feed is robustly constructed in a reinforced moulded case to give a fully enclosed wire feed unit well sealed against the elements. Due to its rugged construction, this is ideal for all site welding in harsh environments & also is very portable. This wire feed unit is designed to run off virtually any constant current or voltage power source, including MMA, TIG, MIG and engine-driven DC power sources. The wire feed unit requires no additional supplies, only welding cable connections, and can run positive or negative polarity, giving very good performances with solid or flux-cored wires.

Site Wire Feeders FAQs

Straight answers to the questions people ask most when choosing and using portable site wire feeders.

What does CC/CV mean on a wire feeder?

CC stands for constant current, the output type of stick and TIG power sources, and CV stands for constant voltage, the output type normally used for MIG welding. A CC/CV feeder is designed to work with either kind of power source.

This means you can often use a feeder with a stick-type machine, an engine-driven welder or a MIG power source, as long as the machine has a suitable DC output and enough current. Always check the feeder maker's list of suitable power sources before connecting it.

What is an arc voltage (voltage-sensing) feeder?

It is a feeder that takes its power and control signal from the welding output itself, by sensing the arc voltage, rather than from a separate mains supply or a multi-core control cable. The motor speed follows the voltage the feeder sees at the arc.

The benefit is simplicity: you connect the welding lead to the feeder, a lead to the work, and the gas hose, and it is ready to go. It makes a good portable set-up for site and fabrication work, and for use with engine-driven welders.

What size of wire spool will it take?

Portable feeders are made for particular spool sizes, with smaller spools being lighter and easier to carry, and larger spools lasting longer between changes. Check the feeder's specification for the biggest spool diameter and weight it can hold.

It is also important that the spool fits on the spindle and runs freely. A spool that is too heavy for the feeder, or that binds, will cause poor feeding. Choose the spool size by how portable you need the feeder to be and how long you want to weld between changes.

How do I set up the voltage and wire speed on a voltage-sensing feeder?

How you set it depends on how the feeder is connected and the type of power source. With a constant-voltage source, the voltage is usually set on the power source and the wire speed on the feeder. With a constant-current source, the feeder speed control mainly decides the arc voltage and the current together.

Follow the maker's instructions for the combination you are using, then make small adjustments while welding a test piece. Listen for a steady crackle, and look for a stable arc and a smooth bead.
