There are two types of path programming that can be used for arc welding: continuous and oscillating.
Continuous path programming is when the welding torch moves in a constant, uninterrupted motion. This type of programming is typically used for straight or simple curved welds. Oscillating path programming is when the welding torch pauses at regular intervals while welding. This type of programming is typically used for more complex welds, such as those with multiple curves or corners.
Both types of path programming have their advantages and disadvantages. Continuous path programming is generally faster and results in fewer errors, but it can be more difficult to control the heat input with this method. Oscillating path programming is slower and can result in more errors, but it allows for better control of the heat input into the weld.
ultimately, the decision of which type of path programming to use depends on the specific weld being made and the preferences of the welder.
