The scale surrounding the BACKGROUND control is calibrated in percentage and does not indicate an am- perage or voltage value.

IMPORTANT: This control may be adjusted while welding.

ELECTROSLOPE 9

The Electroslope in this unit allows the operator (by means of the momentary-contact switch, RMLS-14) to manually select the welding condition and the duration of that condition. The welding conditions that the Elec- troslope provides are PERCENTAGE INITIAL AMPER-

AGE, PERCENTAGE UPSLOPE RATE, PERCENT- AGE DOWNSLOPE RATE, and PERCENTAGE FINAL AMPERAGE. Additionally, adjustment of each condition is provided by means of a control on the front panel of the Electroslope.

IMPORTANT: A momentary-contact type switch (RMLS-14) is supplied with each unit equipped with an Electroslope, It is necessary to press the switch each time a new or different weld condition is desired. This switch allows the operator to manually control the selec- tion of the welding condition and the duration of that con- dition. It further gives the operator the capability of mov- ing rapidly from one condition to the next, if desired. Anytime that the arc is broken (except during the initial condition), the Electroslope will automatically reset to Off. During the initial condition resetting to Off is accom- plished manually by pushing the switch once, provided that an arc has not been established. (For further expla- nation of this switch, see Section 4-5).

4-14. ELECTROSLOPE SWITCH (Electroslope Models Only) (Figure 4-1)

ON

OFF

The Electroslope switch provides two positions: ON and OFF.

When the Electroslope switch is in the OFF position, the Electroslope will be bypassed or out of the welding pow- er source control circuit. When the Electroslope switch is in the ON position, the Electroslope will be connected into the welding power source control circuit.

Ensure that the AMPERAGE switch on the TIG-Unit is in the PANEL position whenever the Electroslope is to be utilized. The AMPERAGE ADJUSTMENT control on the TIG-Unit has complete control of the amperage at this point.

Adjust the PERCENTAGE INITIAL AMPERAGE control for the approximate starting amperage desired. This control is not linear and its settings represent a percent- age of the AMPERAGE ADJUSTMENT control value in use and not an actual amperage reading. Adjustment of the PERCENTAGE INITIAL AMPERAGE control will vary the amperage from minimum of the amperage range used to the setting of the AMPERAGE ADJUST- MENT control in the TIG-Unit. For example: If the Range Switch setting has a amperage range of 100 to 500 amperes and the AMPERAGE ADJUSTMENT con- trol on the TIG–Unit is set for 300 amperes, the setting of the PERCENTAGE INITIAL AMPERAGE control on the Electroslope will then determine the initial amperage be- tween 100 and 300 amperes. If the PERCENTAGE INI- TIAL AMPERAGE control is set at 50, initial amperage will be approximately 200 amperes and will remain at this amperage until the Upslope is energized. The initial amperage can never be higher than the weld amperage provided by the TIG-Unit.

IMPORTANT: This control may be adjusted while welding.

The PERCENTAGE UPSLOPE RATE control is cali- brated in percent and can be adjusted for an upslope rate of approximately .25 (FAST) to 20 (SLOW) sec- onds. With the control set at minimum, initial amperage will rise immediately to the amperage setting of the TIG- Unit AMPERAGE ADJUSTMENT control. When the PERCENTAGE UPSLOPE RATE control is set at 50, it takes approximately 10 seconds for initial amperage to reach welding amperage provided that the difference between initial amperage and weld amperage is great enough. By increasing the control setting to 100, the upslope rate will be approximately 20 seconds.

IMPORTANT: This control may be adjusted while welding.
