SECTION I - INTRODUCTION
1.0 INTRODUCTION
This manual is intended to assist users of this equipment in set-up and basic
operation. Automated welding requires a good deal of operator expertise which
also requires AMI supplied, hands-on training. THIS MANUAL IS NOT
INTENDED AS A SUBSTITUTE FOR THAT TRAINING.
The Model 227 (M-227) welding power supply is part of a complete welding
system intended for the welding of tubes, pipes and fittings (see figure 1). The
complete system consists of the M-227 power supply, adapter cable, gas lines and a
variety of different AMI Welding Heads or Torch Fixture devices (Heads and
Fixtures are sold separately).
The standard version of the M-227 power supply provides GTAW current with
pulsation controls, high frequency arc starting, purge gas controls, weld head arc
rotation, cold wire feed, Arc Voltage Control, Torch Weave/Steering (Oscillation)
and automatic timing functions. Another version is available without the
AVC and
Oscillator functions. The M-227 includes a Remote Operators Pendant and comes
ready to weld. Users need only to supply input AC power, regulated gas source
with flow meter and the appropriate weld head or manual torch.
Some operation conditions may require optional components such as the M227/207-
CW Cooling Unit (for liquid cooled weld heads and torches). The M-227 family
of options also includes memory back up devices, off-line programming and quality
assurance options such as chart recorders.
The system can also be used as a manual welding power source using an optional
manual torch with a variety of manual welding options such as a variable current
foot controller with remote start/stop switch.
NOTE
In-depth weld development instructions, weld head set-up, maintenance and
troubleshooting are contained in other manuals, documents and training classes
and are not included in this manual. Contact your AMI representative for more
information about these items.
