INVERTER ARC WELDING MACHINES
The AMERARC I-400 MST arc welding machine is an inverter type arc
welder with 400 amps output for use with constant current (CC) and
constant voltage (CV) welding operations. The MST model is ideal for
welding with all the major shipboard welding processes:
• Shielded Metal Arc Welding (SMAW-Stick) with all types
and sizes of electrodes
• Carbon Arc Gouging (CAC-A) with gouging rods up to 9 mm (3/8")
• Gas Tungsten Arc Welding (GTAW-TIG), with lift or scratch starting
with current as low as 5 amps
And with a wirefeeder...
• Gas Metal Arc Welding (GMAW-MIG) using the short spray
technique with 0.9 mm (0.035”) solid wire or the spray arc
technique with 1.3 mm (0.052”) wire

• Flux-Cored Arc Welding (FCAW) with cored wires up to

Welding with any process is easy. The operator simply selects a
process, sets his current or voltage, and starts his job. Programmable
controls allow for maximum flexibility, offering either machine or remote
control of electric power and contactor. The MST allows adjustments for
hot starting, hot current and arc control in the SMAW mode, inductance
and material selection for GMAW, and pulse and slope controls for
GTAW. Five welding programs can be saved for standard applications.

The AMERARC I-400 MST weighs only 29 kg so it is not difficult to take
the machine to the work area, avoiding long cable lengths and both
the associated voltage drops and safety concerns due to cables strewn
about the ship.

Arc Welding Machine
208/230/460 Volt, 1/3 ph, 50/60 Hz
The MST accepts any power configuration: 208/330/460 volts,
1/3 phase, 50/60 Hz. The proper input voltage can be selected by
simply adjusting a switch; no tools are required. If the machine
is accidentally connected to improper voltage, SMART LOGIC 1
technology prevents the machine from damage.
