If your Everlast Welding System is overheating and the fan isn't working, it could be due to a damaged fan. Check the fan housing and the fan itself, and replace if necessary. Another possible cause is a loose fan power connector. In this case, tighten the wires and check for any dislodged connectors.
Why is there porosity in my weld with the Everlast POWER MTS 221STi Welding System?
If you're experiencing porosity or discoloration in your weld, or if the tungsten is discolored while using Everlast Welding System, it could be due to several factors related to gas flow and setup. Ensure the shielding gas flow rate is adequate by increasing it at the regulator. Conversely, a high flow rate can also cause issues, so check for kinks in the tubing. Adjust the tungsten stick-out to less than 1/4 inch if it's too far. Insufficient post-flow time can also lead to these problems, so increase it. The TIG cup size might be inappropriate, so increase the cup size or use a gas lens. Finally, check for gas leaks, either internally or externally, due to loose fittings, and ensure the metal is thoroughly cleaned with an approved metal cleaner or acetone.
What to do if there is no arc or output voltage on my Everlast POWER MTS 221STi Welding System?
If your Everlast Welding System shows no arc or output voltage, ensure the work clamp is connected to the correct connector; try changing the polarity. A damaged control circuit can also cause this issue, so check the circuit.
Why does my Everlast Welding System stop welding and the warning light is on?
If your Everlast Welding System stops welding, the warning light is on, and the wire continues feeding without an arc, it indicates that self-protection has engaged. Check for over-voltage, over-current, over-temperature, lower-voltage and over-temperature conditions. If the unit is overheated, allow it to cool. For an over-current (OC) situation, use a shorter wire stick out, a smaller diameter wire, or reduce power settings with large diameter wires. Inspect the power plug for any issues. If the system trips easily, the resistor value might be too low. If OC tripping persists with normal settings, contact Everlast.
Why is the weld quality poor with my Everlast Welding System?
If you're experiencing poor weld quality with your Everlast Welding System, resulting in dirty, oxidized, or porous welds, several factors could be contributing. Drafty conditions can negatively impact weld quality, so eliminate any drafts in the area. The unit's placement on the workpiece may also be blowing gas off due to fan activity, so move the welder. A sticking solenoid can cause issues; check if there is sufficient shielding gas left in the tank. Also, too short of pre-flow or post-flow can lead to poor weld quality, so increase pre-flow or post-flow times.
Why is the tungsten rapidly consumed in my Everlast POWER MTS 221STi Welding System?
If the tungsten in your Everlast Welding System is being rapidly consumed, several factors could be the cause. Ensure adequate gas flow by checking the gas flow rate. Verify you are using the correct shielding gas, specifically 100% Argon, and not using green tungsten. Also, make sure the torch is set to negative polarity. Check the system, regulator, and tank for any leaks that could contaminate the shielding gas.
Why is the arc unstable on my Everlast POWER MTS 221STi?
If the arc is unstable when using your Everlast Welding System, it could be due to a poorly ground or shaped tungsten. Regrind the tungsten to the proper point. A bad work clamp connection can also cause an unstable arc, so connect the work clamp directly to the item being welded. If the metal is indirectly connected through a table or other item, place the torch in DC negative (-).
Why is the tungsten contaminated and the arc green on my Everlast POWER MTS 221STi Welding System?
If the tungsten is contaminated and the arc turns green while using your Everlast Welding System, it could be because the tungsten is dipping into the weld. Check and adjust the stick out to a minimum of 1/8 inch. Alternatively, the stick-out might be too long, so reduce it to less than 1/4 inch.
How to fix Everlast Welding System when power light is off?
If your Everlast Welding System isn't powering on and the power light remains off, the issue could stem from a damaged switch, which would need replacement. Alternatively, a damaged unit fuse could be the cause, also requiring replacement. Lastly, check if the power breaker has tripped and reset it if necessary.
What to do if no gas flows when torch switch is pressed on Everlast Welding System?
If, when pressing the torch switch on your Everlast Welding System, no gas flows, several issues could be at play. First, ensure there's gas in the cylinder and replace it if empty. Check for gas leaks in the pipe and resolve them. The gas solenoid valve might be damaged, so inspect, clean, or replace it as needed. A damaged torch switch could also be the cause, requiring repair or replacement. Finally, a damaged control board could be responsible, so inspect the circuit.
