TECFEED arc voltage inline wire feeder 250A rated

Description

TECFEED 250 wire feeder for MIG/MAG welding using any DC welding power source.

Two model variants; Standard size to take 300mm dia 15kg spools. Compact size to take 200mm 5kg wire spools.

• Rugged construction & excellent portability make these models perfect for all site welding applications in even the harshest of environments.
• Straight polarity (standard MIG/MAG with gas) or reverse polarity (for gas less MIG).
• Suitable for any type of MMA/stick or CC/CV output DC welding power source & can be used for MIG/MAG with gas or with self shielding wires.
• Constructed in a strong reinforced molded case to give a fully enclosed wire feed unit sealed against the elements.

Functions & features ;

• Gas solenoid fitted.
• Heavy duty 250A ‘Albright’ contactor fitted for non live torch.
• 2T/4T torch trigger latching function.
• Adjustable burnback control.
• Wire inching switch.
• Torch Euro connection.

Simple connection to any power source just plug in one welding cable to the rear of the wire feeder, the other polarity connect to your workpiece. Clip on a volts ref wire from feeder to the workpiece & get welding!

*June 2026 update – even better performance – now guaranteed no contactor or gas drop outs when welding with a CC power source at low power *

350A/500A heavy duty industrial models also available – see TECFEED 350 & 500 Expert models.

Further information – CC vs CV power sources;

For the very best MIG welding performance a CV (constant voltage output) is preferred. With CV a perfect arc condition as you would expect from any good workshop MIG can be achieved permitting welding from very thin sheet material up to structural steel fabrication. Many of the more expensive engine driven power sources have CC/CV output which is the perfect solution.

However, more popular power sources tend to have only CC output designed mainly for MMA stick electrode welding. For use as a MIG welder these power sources have some limitations at lower power particuarly in dip transfer mode. The worst case is trying to MIG weld thin materials in dip transfer with a large diameter MIG wire, this can result in an unstable arc condition. If the CC power source is fitted with ‘ARC FORCE’ control this can improve the arc condition to be almost as good as as a CV power source. Also reducing the wire diameter helps arc stability at low power. At increased welding power, globular & spray transfer superb MIG welding results are achieved with a CC power source.
