Electric Arc Spray
Commonly referred to as twin wire arc or metallizing, electric arc thermal spray is one of the most productive and economical thermal spray processes. The coating material, in wire form, is deposited on targeted substrates in molten form, creating extremely strong bonds. These coatings can serve as protective, decorative, or functional purposes, and are known for longevity, durability, and versatility. Thermach’s Electric Arc systems are designed to lower operator fatigue, are capable of robot integration, and significantly reduce maintenance costs.
Following you'll find Equipment, Parts & Information for the Thermach Electric Arc Thermal Spray Coating System.
AT-400 Twin-Wire Electric Arc Spray System
The AT-400 high performance arc spray system combines the benefits of a “push” method wire feeder with the power of a 400-amp arc spray system.
Consisting of a robust “push” method wire drive unit, reliable power supply, and light weight torch, the AT-400 electric arc spray system was designed to control costs and operator fatigue. With the feedstock and drive system located on the control console instead of the torch, your operator will experience less fatigue, as well as save you cost, and maintenance time compared to that of a conventional pull or push/pull system.
In addition to our hand-held torches being light, they also utilize our patented QuickChange Wire Guides.

Wire Guide Options
Thermach offers several wire guide options for our customers. Our patented Quick Change guides fit both our AT-400 Standard, 1/8”, and Pull torches. Our other guides thread into our extension torches.
Operators can replace the consumable wire guides in less than 30 seconds using no tools with the exclusive patented Quick Change Wire Guide System. Unlike wire guides that are screwed into the torch body, the Quick Change guides can be rotated 180° when they are close to being worn out, adding more life.
Air Cap Options
Expect optimal airflow and atomization with a variety of air caps designed to
produce the correct spray pattern for any job.
The High Velocity Air Cap produces a small, concentrated spray pattern and smooth coatings. Typical uses for this air cap are engineered coatings, which require low oxides and a tight, collimated spray pattern.
The Fan Spray Air Cap provides the largest possible spray area.
It is typically employed with zinc and aluminum feedstocks.
The Open Air Caps are used in processes where larger, coarse particles are desired.
Great for anti-skid applications.
Most air cap styles can be purchased with or without an arc shield. Arc shields are great when spraying out in the open, as they shield the operator from the torch’s UV light. Open arc caps, however, are great in automated operations or when spraying substrates that would reflect particulate back at the torch, as these particulates would buildup in a shielded cap.
