Thermach Electric Arc systems are specially designed to help lower operator fatigue and significantly reduce maintenance costs. Our AT-400 system uses the “push” method, the driving force is a bigger, more robust wire drive motor located within the control console instead of the torch. Our lightweight AT-400 torch with quick change wire guides delivers ergonomic benefits unavailable with any other system.

Imagine having the power and flexibility of a 400 amp spray arc spray system with only 20% of the maintenance costs of conventional pull or push-pull systems. You’re not dreaming. The AT-400 Wire Arc Spray System is specially designed to minimize operator fatigue and lower maintenance costs due to the lightweight torch (2.3 lbs) that features no moving parts.

Imagine again replacing the consumable wire guides in less than 30 seconds using no tools with the exclusive patent-pending Quick Change Wire Guide System. The QuickChange four drive roll per wire system features either U-groove or VK-groove drive rolls for positive, slip-free wire feeding. No tools are needed for drive roll or wire diameter changes.

An advanced closed-loop regenerative wire drive control system ensures consistent and repeatable coatings. Expect optimal airflow and atomization with a variety of air caps that are designed to produce the correct spray pattern for any job. From the High-Velocity Air Cap featuring Converging/Diverging Air Chamber Geometry, which produces tight, dense spray patterns and smooth coatings, to the Fan Spray Air Cap, which provides the largest pattern.

AT-400 Power Supply This reliable, three-phase, SCR rectified, constant potential DC power source provides arc voltages between 18-40 volts, permitting operation between 15-400 amps at 100% duty cycle. The cooling fan operates only when needed, minimizing dirt, dust, and moisture buildup within the power supply thereby minimizing maintenance.

Quick Change Wire Guides A patented design directs high velocity, laminar flow air across the arc zone. An On/Off trigger switch is supplied on the detachable gun handle to control the wire feed, compressed air, and contactor of the AT-400 Power Supply. The AT-400 Gunhead is supplied with several hardpoints for mounting to robots, gun manipulators, and fixtures.

Fan Spray Air Cap Typically employed with zinc and aluminum feedstocks. This air cap produces a spray pattern with the largest possible spray area.

High-Velocity Air Cap This air cap produces a small, concentrated spray pattern. Typical uses of this air cap are engineered coatings, which require low oxides and a tight collimated spray pattern.
