Frequently Asked Questions

Q: What is the ideal gas flow rate for E71T-GS welding wire?

The recommended gas flow rate for this flux-cored wire is generally between 20-25L/min to ensure proper shielding and weld quality.

Q: How should I store the welding wire to avoid degradation?

Storage humidity must be kept below 60%. Non-vacuum-packed wire should be used within six months, while vacuum-packed wire lasts up to one year.

Q: Can E71T-GS be used on galvanized sheet metal?

Yes, it is specifically recommended for lap and butt welds on galvanized sheet metal and roofing.

Q: What is the suggested dry extension length for this wire?

For optimal performance and arc stability, the dry extension length should be maintained between 15-25mm.

Q: Which current type is required for the CB-E501T-GS model?

The CB-E501T-GS model is designed for use with DC- (Direct Current Negative) polarity.

Q: What surface preparation is necessary before welding?

To ensure a high-quality weld, the welding workpiece should be thoroughly degreased and derusted before starting the process.
