MODEL 227 OPERATION MANUAL 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...

MODEL 227 OPERATION MANUAL SECTION I - INTRODUCTION 1.1 SAFETY PRECAUTIONS This section contains cautions and warnings concerning the operation of this equipment and welding equipment in general. However, in addition to reading this manual and before operating this or any welding equipment, users should reference and be familiar with “ANSI-49.1 Safety in Welding and Cutting”. This standard is published by the American National Standards Institute and the American Welding Society.

MODEL 227 OPERATION MANUAL SECTION I - INTRODUCTION 1.1 SAFETY PRECAUTIONS

1.2 OPERATIONAL PRECAUTIONS The following is a check list for operating personnel to follow to insure minimum system down-time due to improper operation and handling: 1. TOO AVOID severe equipment damage VERIFY that the M-227 is connected to the correct Input AC power (see section 3.1). 2. Before operating, check all fittings and connectors for proper seating and that all protective boots are in place. If not properly seated or protected, short circuits, poor connections or inert gas leaks could occur. 3. The M-227 is intended for typical GTAW gases ONLY. NEVER CONNECT OXYGEN OR ACETYLENE...

MODEL 227 OPERATION MANUAL SECTION I - INTRODUCTION 1.2 OPERATIONAL PRECAUTIONS 6. Before operating, insure that the M-227 has adequate air flow. Do not restrict the intakes or exhaust vents of the power supply. 7. Before operating, always insure that there is bare metal contact between the weld head components which connect to GROUND (clamp inserts, etc.) and the tube or pipe to be welded. 8. When storing or handling weld heads, always keep them in the protective containers they are shipped in, or optional carrying case, until ready to install. 9. When operating, storing or handling,...

MODEL 227 OPERATION MANUAL SECTION I - INTRODUCTION 1.3 RF AND EMI TRANSMISSIONS 2. RF REGULATION The FCC regulates the RF emission limitations for welding equipment by the use of an IEC (international) regulation created by the Special Committee on Radio Interference (known as CISPR) subcommittee B. The regulation of record is: CISPR/B/63 “CODE OF PRACTICE FOR THE USE OF WELDING AND CUTTING POWER SOURCES UTILIZING RADIO FREQUENCY VOLTAGE FOR STARTING OR STABILIZING THE ARC.” The regulation states that due to the variety of work requirements and conditions it is virtually impossible to...

SECTION I - INTRODUCTION 1.3 RF AND EMI TRANSMISSIONS 3. RF PROTECTION (continued) Most RF noise interference problems are going to be either set-up related or caused by poor or no filtering on the behalf of the equipment that is being interfered with. Most problems are easily correctable but each one must be looked at on a “case by case basis.” 4. EMI SUPPRESSION The M-227 is equipped with a heavy-duty Pi-Network filter, connected to the input power line, to prevent propagation of EMI either into or out of the M-227. The all-metal enclosures and internal shields prevent radiated EMI. 1.4...
