Why is there excessive electrode consumption in my Smootharc Welding System?
- J
  Jamie RileyAug 2, 2025
  Excessive electrode consumption in your Smootharc Welding System can stem from several factors. Check for inadequate gas flow and increase it as needed. Ensure your post gas flow is sufficient, aiming for 1 second per 10 amps. If the electrode size is too small for the current, switch to a larger one or adjust polarity. Remove any contamination from the electrode. If the torch is overheating, replace the collet, potentially trying a wedge or reverse collet. To prevent electrode oxidation during cooling, increase the post flow time before shutting off the valve. Finally, verify you're using the correct shield gas, avoiding any with oxygen or CO2.

What causes porosity in the weld deposit of a Smootharc Welding System?
- N
  Nathan YoungAug 7, 2025
  Porosity in the weld deposit of your Smootharc Welding System can occur due to entrapped impurities like hydrogen, air, nitrogen, or water vapor. Avoid welding on wet material and ensure adequate gas pre-flow time to remove condensation. Inspect gas hoses and connections for any leaks. If using aluminum filler material, dry it in an oven before welding. Replace oily or dusty filler material. If the base metal contains alloy impurities such as sulfur, phosphorus, lead, or zinc, consider switching to a different, more weldable alloy composition. Reduce travel speed to prevent rapid freezing of the weld, which can trap gases.

How to prevent cracking in welds with a Smootharc 180 Multiprocess Welding System?
- R
  ricardochavezAug 12, 2025
  Cracking in welds on your Smootharc Welding System can be addressed by focusing on several factors. For hot cracking in heavy sections or metals prone to it, increase the weld bead cross-section size and adjust the weld bead contour. Check the fit-up gap and reduce welding speed. To prevent post-weld cold cracking, preheat the material before welding, use pure or non-contaminated gas, increase the bead size, prevent craters or notches, and consider changing the weld joint design. For center line cracks in single pass welds, increase bead size, decrease root opening, use preheat, and prevent craters. To avoid under bead cracking from brittle microstructure, eliminate sources of hydrogen and joint restraint, and use preheat.

What to do if a Smootharc Welding System has an erratic arc?
- T
  tina31Aug 17, 2025
  An erratic arc in your Smootharc Welding System can result from several issues. Maintaining a short arc length helps correct incorrect voltage from an arc that is too long. If the current is too low for the electrode size, switch to a smaller electrode or increase the current. Remove any contamination from the electrode. If the joint is too narrow, open the joint groove. Ensure your shield gas isn't contaminated, looking for dark stains on the electrode or weld bead as indicators. If the base metal is oxidized, dirty, or oily, clean it with appropriate chemical cleaners, a wire brush, or abrasives before welding.

What causes inadequate shielding in a Smootharc 180 Multiprocess?
- M
  Michael PonceAug 27, 2025
  Inadequate shielding in your Smootharc Welding System can be caused by several factors. Check for gas flow blockages or leaks in the hoses or torch, and eliminate any obstructions or leaks found. If the travel speed is too high, exposing the molten weld to atmospheric contamination, use a slower travel speed or carefully increase the flow rate. Set up screens around the weld area to protect from wind or drafts. Reduce excessive electrode stickout and consider using a larger size cup.

Why does my Smootharc 180 Multiprocess Welding System have tungsten inclusions in the weld?
- Z
  Zachary ValentineNov 21, 2025
  Tungsten or oxide inclusions in the weld of your Smootharc Welding System can occur due to several reasons. Ensure you're using the proper lift arc starting technique. Many codes do not allow scratch starts, so use a copper strike plate or a high-frequency arc starter. If the current is too high for the tungsten size, reduce the current or use a larger electrode. Avoid accidental contact of the electrode with the puddle or filler rod by maintaining proper arc length and distance. Reduce excessive electrode extension to recommended limits. Ensure adequate shielding by increasing gas flow, shielding the arc from wind, or using a gas lens. Use the correct gas, avoiding ArO or ArCO GMAW (MIG) gases for TIG welding. Wire brush and clean the weld joint prior to welding to remove heavy surface ox...
