Project Description

207 fixed pic for frontThe Model 227 is a 100/225 A pre-programmed / programmable, inverter-type, GTAW welding power supply and controller designed for (but not limited to) automatic orbital welding applications that require the addition of filler material.
Welds produced by this machine, together with Arc Machines’ weld heads, meet or exceed the specifications required by industries as diverse as: food, dairy, brewery, pharmaceutical, power generation, petrochemical, chemical, pulp and paper, nuclear, shipbuilding, etc. Its small size and rugged casing makes it useful in field applications where portability is required. High-integrity, code-quality welds are easily reproduced at the touch of a button.


  • Internal memory for up to 100 multi-level, multi-function weld schedules
  • 8 multi-level functions for total process control
  • Programmable, continuous or pulsed current, rotation, wire feed, oscillation and AVC, 100 levels per pass
  • Dust/moisture-proof stoft-touch membrane switches
  • Standard software prompts in multiple languages
  • Built-in, high speed printer
  • Off-line programming option available (PC Compatible)
  • Key-switch to limit operator access
  • Standard remote operator’s pendant
  • Optional water cooling unit
  • Optional external memory module

Compatible AMI weld heads: Fusion weld heads without filler wire – Model 96, Model 6, Model 8 series, Model 9 series Pipe weld heads with filler wire - Model 81, and Model 15 Open-frame weld heads with or without filler wire - Model 79 series, and Model 95 series
