How to fix poor penetration with Impax IM-MMA140 Welding System?
If you're experiencing poor penetration, it could be due to the weld current being too low or the arc being too long. To resolve this, adjust the settings and move the electrode closer to the workpiece.
What to do if Impax IM-MMA140 has excessive penetration?
Excessive penetration can occur if the weld current is too high or the torch is too far from the workpiece. Adjust the settings and ensure you are welding with the electrode at the correct distance from the workpiece.
Why is the arc unstable on my Impax Welding System?
An unstable arc could be caused by impurities in the weld area. Make sure to clean the weld area thoroughly before welding.
How to prevent porous welds with Impax Welding System?
Porous welds can result from rusty or dirty joints. Ensure you clean the weld area prior to welding.
What to do if there is no weld current in Impax Welding System?
If there is no weld current, it could be due to a break in the earth lead. Check and clean up the connections and consider replacing the torch or lead.
Why is the weld current interrupted on my Impax Welding System?
The weld current might be interrupted because the thermal trip has operated. Allow the welder to cool down.
How to fix no weld current (plug fuse blowing) on Impax IM-MMA140 Welding System?
If there's no weld current and the plug fuse is blowing, the rectifier might be blown. Replace the rectifier.
