OPERATION Select the output current I with sequencer control button, turn the control knob to meet the needs of the job. Higher amps for thicker material, lower amps for thinner material. FIGURE 15 Electrode Holder Work Clamp Specify your Arc Force setting, the Arc Force increases temporary the output current, used to clear intermittent connections between the electrode and the weld puddle that occur during...
OPERATION Very little routine maintenance is necessary to keep your TIG-225P running in top condition. No specific schedule can be set for performing the following items; factors such as hours of usage and machine environment should be considered when establishing a maintenance schedule.
