If there is no arc or output voltage from your Everlast Welding System, ensure the work clamp is engaged in the correct connector to change polarity. Also, the control circuit could be damaged, so check the circuit.
Why is the tungsten rapidly consumed in my Everlast PowerMTS 251Si Welding System?
Rapid tungsten consumption in your Everlast Welding System can be due to several factors. Ensure adequate gas flow and check for leaks throughout the system, regulator, and tank. Verify you are using 100% Argon. Avoid green tungsten and use red thoriated or other types. Ensure correct polarity by placing the torch in the negative position. If the tungsten is contaminated and the arc turns green, adjust the stick out to a minimum of 1/8 inch. If the tungsten is melting, reduce amperage, increase tungsten size, and reduce stick-out to less than 1/4 inch. If you notice porosity or discoloration in the weld, increase the flow rate on the regulator, check for kinks in the tubing, increase post-flow time, reduce stick-out, increase cup size, or use a gas lens. Clean the metal thoroughly with an ...
Why doesn't my Everlast Welding System's wire-feeder work?
If the wire-feeder on your Everlast Welding System isn't working, several issues could be the cause. The motor may be damaged, or the fuse might be blown, requiring a check and possible replacement. The control circuit could be damaged, necessitating a board inspection. The tensioner might be loose, or the wire could be slipping on the rollers; in this case, increase the tension and ensure the correct drive roll size and type are used, making sure the wire is properly seated in the groove. The drive roller may not fit the weld wire diameter, requiring a change of roller or wire size to match. A damaged wire spool should be replaced. A jammed gun liner should be repaired or changed; clear any wire and clean the liner with compressed air. Finally, slag or burn back may have jammed the contac...
Why does the rod stick in Stick mode on my Everlast PowerMTS 251Si Welding System?
If the rod sticks in Stick mode on your Everlast Welding System, it could be due to several reasons: the arc force/Hot Start is set too low, your arc striking method is poor, you're using the wrong polarity, the amperage is too low, or you're using wet or wrong welding rods. To fix this, check the polarity and Hot Start settings. Increase arc force control/Hot Start. Change your arc striking method. Increase the amperage. Use fresh welding rods when possible.
Why won't my Everlast PowerMTS 251Si Welding System arc in Stick mode?
If your Everlast Welding System won't arc in Stick mode, check the connections. There may also be an inverter issue.
What to do if the Everlast PowerMTS 251Si power light isn't on?
If your Everlast unit is switched on but the power light isn’t on, the switch may be damaged and needs replacement. Alternatively, the unit fuse may be damaged and also needs replacement. A tripped power breaker could also be the cause; try resetting it.
Why does the nozzle arc to the workpiece on my Everlast PowerMTS 251Si Welding System?
If the nozzle arcs to the workpiece during welding with your Everlast Welding System, it's likely that the nozzle is plugged with spatter. Clean the nozzle and use a nozzle dip to prevent this.
How to stop intermittent or wandering arc on my Everlast PowerMTS 251Si Welding System?
An intermittent or wandering arc with your Everlast Welding System can be caused by a work clamp that isn't secure or is damaged, or by windy conditions. Check and/or replace the work clamp, change the clamp's position, and attach it directly to the work. Also, move out of the wind.
Why does the wire burn back and seize in the tip of my Everlast PowerMTS 251Si Welding System?
If the wire burns back and seizes in the tip of your Everlast Welding System, it could be due to the wrong contact tip size or too much burn back time set. To fix this, match the tip size to the wire diameter and reduce the burn back time. If using aluminum, use a tip designed for aluminum or one size larger than the wire.
What to do if my Everlast Welding System stops and the warning light is on?
If your Everlast Welding System stops welding, the warning light is on, and the wire continues to feed without an arc, it means the self-protection feature has engaged. Check for over-voltage, over-current, over-temperature, lower-voltage, and over-temperature conditions. If the unit has overheated, allow it to cool. If it's an over-current issue, use a shorter wire stick out or smaller diameter wire, or reduce power settings with large diameter wires. Check the power plug for problems. If the over-current trips easily, the resistor value may be too low. (Contact Everlast if the over-current is tripping regularly with normal settings.)
