Why does my Eastwood Welding System arc trigger but not start?
The arc might not start due to an incomplete circuit. Ensure the ground connection is clean and close to the welding area, welding towards the ground. Also, verify you're using the correct tungsten for the base metal; thoriated tungsten is generally used for steels. Finally, check that your shielding gas cylinder is fully open and set to the correct flow rate.
What to do if I see porosity in weld bead with Eastwood Welding System?
Porosity in the weld bead can be caused by several factors. First, adjust the flow rate of the shielding gas and check for loose fittings. Second, ensure the filler metal is clean and free of oil, debris, or moisture. Third, clean the base metal to remove any contaminants. Also, make sure you are welding in an area without wind or fans. Finally, adjust the tungsten so that 1/8” to ¼” inch protrudes from the collet.
What causes contamination in weld bead with Eastwood Welding System and how to resolve it?
Contamination in the weld bead can stem from contaminated tungsten, filler metal, or the base metal. Remove the tungsten from the torch, break off the contaminated section, and resharpen it. Clean the filler metal to remove any oil, debris, or moisture. Thoroughly clean the base metal, removing any oil, debris, coatings, or moisture; for cold rolled steel, remove any mill scale.
What causes weld bead cracking with Eastwood Welding System?
Weld bead cracking can be caused by too much heat in the material, so reduce heat and allow more time between passes. It can also occur if the base metal is absorbing too much heat; preheat the base metal, consulting welding codes for requirements. Finally, ensure you are using the appropriate filler wire type and diameter for the joint being welded.
How to prevent material warping when using Eastwood Welding System?
To prevent material warping, ensure the workpiece is tightly clamped and weld while the clamps are in place. Add more tack welds to increase rigidity. If there is too much heat, spread the welding out around the area using stitch welding techniques, alternating sides, and allowing the pieces to cool between passes.
How to fix arc wandering with Eastwood Welding System?
Arc wandering and difficulty concentrating heat can result from several issues. Ensure the tungsten is correctly prepped. Adjust the shielding gas flow rate and check for leaks. Remove, break off the contaminated section, and resharpen contaminated tungsten. Maintain the tungsten 1/8 to 1/4 inch from the workpiece. Verify the ground connection is clean and close to the welding area. Clean the base metal to remove any contaminants.
Why is my tungsten melting with Eastwood Welding System?
Melting tungsten can be due to poor gas flow; adjust the shielding gas flow rate and check for leaks. Using the wrong size tungsten can also cause this; increase the tungsten diameter, referring to a sizing chart. Finally, ensure you are using 100% Argon when TIG welding.
What to do for tungsten contaminated with Eastwood Welding System?
If the tungsten is contaminated due to contact with the base metal, keep the tungsten 1/8 to 1/4 inch from the base metal. If contact occurs, break off the end and resharpen immediately.
What causes a crater in the end of the weld bead with Eastwood Welding System?
A crater at the end of the weld bead can occur due to insufficient shielding. Keep the torch on the base metal while the post-flow shielding gas flows to protect and cool the metal and tungsten. Also, not enough filler material can cause this issue; reduce current and add more filler at the end of the weld, and consider back-stepping to prevent crater formation.
