SECTION I - INTRODUCTION
1.0 INTRODUCTION
This manual is intended to assist users of this equipment in set up and basic
operation. Automatic fusion welding requires a good deal of operator expertise
which requires AMI supplied training. THIS MANUAL IS NOT INTENDED AS
A SUBSTITUTE FOR THAT TRAINING.
The basic Model 207A (M-207A) welding power supply is part of a complete
welding system intended for fusion welding of metal tubes, pipes and fittings (see
Figure 1). The complete system consists of the M-207A power supply, adapter
cable, gas lines and any of the AMI Model 9 (M-9) series of tube welding heads
(M-9 heads sold separately).
The M-207A power supply provides GTAW current with pulsation controls, high
frequency arc starting, purge gas controls, weld head arc rotation and automatic
timing functions. The M-207A is supplied (as standard) 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 operating conditions may require optional components such as the remote
pendant option (M-207-RP), weld head cooling unit option ( M227/207-CW or
M207-CW ) and extension cables. The M-207A family of options also includes
quality assurance options such as chart recorders and Weld Data Recording
Software.
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 or a 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.
