The Four Welding Features:
NOTE: The following four welding features are designed to optimize specific welding processes. (See Figure K.)
1.2-TIME: Typically, the standard welding process used. To operate, turn the Wire Speed Mode Selector (6) to its 2-Time setting. Squeeze the Welding Gun Trigger (18A) to start the Pre-Gas. Then, weld accordingly. Release the Welding Gun Trigger to stop welding. The Post-Gas will continue to deliver the protective gas according to the setting of the Post-Gas Timer (5D).
(See Figures D, F, and K.)
2.4-TIME: The benefit of this process is that there is no need to continuously squeeze the Welding Gun Trigger (18A) during a long welding job. To operate, turn the Wire Speed Mode Selector (6) to its 4-Time setting. Squeeze and quickly release the Welding Gun Trigger to start and stop welding. The Post-Gas will continue to deliver the protective gas according to the setting of the Post-Gas Timer (5D). (See Figures D, F, and K.)
3.SPOT AND PAUSE: This process reduces the number of times the operator must squeeze the Welding Gun Trigger (18A) while spot welding. This process also allows the operator to lower the welding heat for thin material to avoid burn-through. To operate, turn the Wire Speed Mode Selector (6) to its Spot and Pause setting. By squeezing the Welding Gun Trigger (18A), the operator can weld and pause in cycle according to the settings of the Pause Timer (5A) and Spot Timer (5B). (See Figures D, F, and K.)
4.INTERVAL: This process allows the operator to produce the same length and quality of the welding bead more efficiently. To operate, turn the Wire Speed Mode Selector (6) to its Interval setting. By squeezing the Welding Gun Trigger (18A), the operator can weld in one cycle according to the preset welding time. (See Figures D, F, and K.)
