8.PULSE TIG CONTROL – The Pulse TIG feature built into the PRECISION TIG® 225 is simplified to be a single knob control which sets the Pulse Frequency over the peak pulses/sec. range of about

0.1 to 20 pulses per second:

•Full CCW (min.) setting of the control knob shuts off Pulse TIG (0.0 pps).

•Peak Pulse level is set by the Max. Output Control and the Remote Amptrol (if used).

•Background Current level is typically optimized at a fixed 50% of Peak Pulse level setting.

•Peak Pulse % On-time is typically optimized at a fixed 50%.

A Green light "blinks" with each Peak Pulse to indi- cate the Pulse TIG Control setting before and dur- ing welding.

9.THERMAL SHUTDOWN LIGHT This Yellow LED panel light turns on if the machine output is shut- down because internal overheating has occurred, and turns off when cooled to reset.

10.REMOTE RECEPTACLE – Provides for connec- tion of remote control and/or arc start switch only in TIG Mode: (There is no remote output control capability when stick welding).

•Plugging a remote current control (Amptrol) into this receptacle automatically switches the output control from the panel Max Output Control (See Item 5) to the remote control.

•The connected remote control will then control the output current between the Min. range of the machine and the setting of the panel Max Output Control.

•Switching Mode Switch (See Item 3) to Stick will automatically disable the connected remote con- trol and switch the output control back to the Max Output panel control.

11.ELECTRODE/GAS OUTPUT RECEPTACLE - This quick connect Twist-Mate™ receptacle pro- vides electrical connection to the electrode holder and cable for Stick welding and a combined electri- cal and gas connection for the TIG torch when TIG welding.

12.WORK CABLE - This 10ft.(3.05m) cable with work clamp is factory connected to the welder and its clamp is connected to the work piece to complete the welding circuit. Refer to Machine Grounding and High Frequency Interference Protection in the Installation section of this manual for the prop- er procedure on grounding the work clamp and work piece to minimize high frequency interfer- ence.

POWER-UP SEQUENCE

When the PRECISION TIG® 225 Power switch is ini- tially turned On , the following will be observed: (Refer to this Section Controls and Settings Figure B.1)

•The cooling fan will run for about 5 seconds.

•The previous (prior to Power Off) settings of Mode and Maximum Output will be initiated.

•If in TIG Mode, the shielding gas solenoid valve will be activated for the time set by the Post Flow Time control.
