    SAFETY FIRST! AHP Welding Systems takes safety seriously. You should as well. Please read this entire manual before using. Keep a copy of this manual available for all employees or potential users of this machine to read and thoroughly review before use.

  • Page 6: Safety Warning, Dangers, Cautions And Instructions

    Safety Warnings, Dangers, Cautions and Instructions NOTICE. This unit manual is intended for users with a basic working knowledge and skillset in weld- ing. It is your responsibility to make certain that the use of this welder is restricted to persons who have read, understand and follow the warnings and instructions in this manual.
  • Page 7 Safety Warnings, Dangers, Cautions and Instructions DANGER! Welding and cutting operations pose serious inhalation hazards. Some of these hazards are immediate while others are cumulative in their effect. Do not weld in enclosed spaces or in areas without adequate ventilation. Fumes and gases released in the welding and cutting opera- tions can be toxic.
  • Page 8 Safety Warnings, Dangers, Cautions and Instructions CAUTION! Welded metal can stay hot long after welding is completed. Burns may occur. Always wear gloves or use tongs/pliers when handling welded or cut metal. Remember the heat from the metal may catch other material on fire. Always have a fire-proof area ready to place welded compo- nents until they fully cool.

    225Xi Component Identification and Explanation of Function Control Panel Features The control panel layout has been arranged with convenience and speed of adjustment in mind. The graphics on the panel have been grouped and color coded (the brackets themselves) to remind the user what value the controls are indexed in and/or what function the con- trols are related to.

The Down-Slope is used exclusively with the 2T/4T settings while the torch switch is in use. This provides a “crater fill” time and gradually diminishes the welding amperage down to the End Amps setting. This provides the user time to properly fill the crater left at the end of the weld pool.

It can help improve arc control at higher frequencies, or im- prove weld appearance at lower frequencies (typically 1-3 Hz) by helping the user to time filler metal addition and forward travel speeds. Pulse is actually the oscillation of the welding amperage between a relatively high amp value, and a lower amp value.
