Features
Chrome-Copper Electrode Holders
The chrome-copper electrode holders, designed for straight and angled fittings, provide a longer life span for consumables and heavy-duty applications.
Adjustable Electrode Performance
The electrode stroke and force can be adjusted to suit your needs. A microswitch will start the welding cycle when the preset value is reached.
Built to Last
The transformer, arms and electrodes are water-cooled, with an epoxy resin coating on the transformer, for a longer working time and lifespan. It also comes fitted with a TECNA TE101 microprocessor control unit.
Adjustable Arms & Foot Pedal
The foot pedal and arm lengths are adjustable, allowing for more flexibility while working.
