• All water, rust and oil should be complexly removed from base material to prevent cracking and blowholes.

• For improved impact properties, avoid used of excessive amperage levels.

• Backstep method should be applied to prevent blowholes and pits during arc start.

• Arc length should be kept as short as possible during welding

• If weaving is required, the width should not exceed 3x the diameter of the electrode.

Redrying

• All controlled hydrogen electrodes will perform optimally when they are dry.

• Excellent protection against moisture pick-up in good storage conditions.

• Should redrying be necessary, remove electrodes from the packet/ container and spread thinly and evenly on racks in a ventilated oven

• For electrodes that have had a short or mild exposure to the atmosphere then re-drying at 572 F^0(300 ^0C) for 1 hour will be sufficient

• For electrodes that have been exposed to longer or more aggressive conditions or for critical work re-drying at 572-662 ^0F(300-350 ^0C) for 1-2 hours is recommended. After re-drying electrodes should be stored in a hot box
