THOMAS Welding systems has developed a small, light, compact 300 A  studwelding machine, based on the most recent inverter technology (5th generation). The weight of the new pins & studs  welder is only a third of currently available products, particularly suitable for a variety of repair, installation and supply work as well as for light or medium duty use.

When designing the machine, THOMAS Welding Systems was wanted to achieve simplicity and versatility so welding values can be found as fast as possible.

The power supply operates on single phase power 230 V - 16 A.

The COMPACT 300i is a lightweight 11 Kg portable inverter drawn arc studwelder and is capable of welding from Ø 3 mm up to Ø 8 mm pins and M 3 to M 8 studs. (M10)

The weld time is infinitely adjustable for preciseness.

Weld current regulation improves stud welding consistency.

The superior chopping frequency of 30 KHz, provides a much smoother arc than any competitive inverter-based stud welder. Because the COMPACT 300i uses inverter technology, it delivers faster arc response, excellent arc ignition, has superb arc performance and superior repeatability compared to traditional transformer/rectifier-based stud welders. 

Designed with cooling fan and thermo-overload circuitry.

The Bantam A-38 stud welding gun is a multi-purpose, compact, lightweight tool designed for use in the arc stud welding process. 

This compact gun is ideal for fielding welding work, and its compact size enables use in hard to reach areas.

Welds any length pins with a diameter range of Ø 3 mm through Ø 8 mm. 

Welds any length studs with a diameter range of M 3 through M 10. 

Features:

- Compact and tough for heavy duty use.

- Space saving due to internal welding cable.

- More powerful solenoid for faster welding.
