Tip #5: Calibrate the Touch-to-Tungsten System

Over time, the mechanism that touches the tungsten to the workpiece can wear slightly. Follow the manufacturer’s calibration procedure once a month to ensure consistent arc gaps.

Tip #6: Create a Library of Welding Schedules

Once you perfect a setting for a specific pipe size and wall thickness, save it as a named program. This library allows for instant job changeovers, saving significant time on repeat work.

Tip #7: Use the Wire Fill Option for Defective Joints

If you encounter a joint with minor gaps or misalignment, use the wire filling program. It allows you to add filler metal to fill the gap, preventing the need for re-welding.

Common Mistakes to Avoid

1. Mistake: Not properly purging the inside of the pipe before welding. Solution: Always use a trailing gas shield and a back-purge for stainless steel to prevent sugar (oxidation) on the root side.
2. Mistake: Ignoring the warning signs for low coolant levels. Solution: Set a weekly visual check of the coolant reservoir. Overheating can cause costly damage to the inverter.
3. Mistake: Using the wrong welding parameters for the specific alloy. Solution: Always consult a welding procedure specification (WPS) for the specific material you are welding.
4. Mistake: Forgetting to set the correct pre-flow and post-flow times for shielding gas. Solution: Ensure the post-flow time is long enough to protect the hot weld from atmospheric contamination.
5. Mistake: Expecting the machine to fix a poorly fitted joint. Solution: The orbital head is not a substitute for proper joint preparation. Always ensure pipes are cut square and free of debris.
