I have a kende mig 105 gasless welder,but the wire isn't getting fed through on the feed wheel,tried different welding wire and also turned the wheel,tried tightening the wheel,slackening it as well,i
Here's a few things you can check:
When gun trigger is pulled, do the drive wheels turn? If they aren't, pull the trigger again; do you hear anything within the machine (contactors closing, gas solinouds opening, any clicking, etc.) that would indicate the trigger circuit is functional?
If the drive wheels are turning, but wire isn't being pushed thru the mig gun, check for proper drive roll vs. wire size. If that is correct, check gun liner for obstructions. Flux cored wire tends to stop up a wire liner fairly quickly.
Mig welder powers up but only clicks when trigger is squeezed
1] Remove the power cable from the power. (socket on the wall) remove the top cover there should be a fuse located on the wiring panel.
2] perform all your house keping- like, all plugs and socket are tight, the correct contact tip with the the right wire size, roller/s are also the correct ones for the wire size and are turning if they are turning but not feeding the wire, then, the rollers need to be tightend , get back to us.
My welder is tripping the
I am having the same exact problem on an old Hobart Beta Mig 200
sometimes i can weld for 5 minutes and other times as soon as I hit the trigger it trips the 50amp breaker. Any help?
Miller 325 EFI welder motor won't start. seems like fuel delivery issues.
Likely fuel delivery i.e. low fuel pressure at the injectors.
Causes;
Low fuel
Fuel filter plugged
Fuel supply line plugged
Lift fuel pump - insufficient fuel supply
Fuel pump (lift or module) - internally plugged
Pressure regulator not functioning properly
Minimum module (injector) pump voltage is 7VDC measured at the pump. The unit requires a battery with sufficient charge to provide cranking current to the starter and feed the fuel pump (lift and/or module).
Once running, the charging system must provide sufficient current to maintain a battery voltage in excess of 13VDC. Less than 13VDC implies failing charging system and/or battery.
Which type of dissimilar welding materials combination is good for welding?
Dissimilar welding refers to the process of connecting materials with different alloys through welding. The filler material and both metals need to be evaluated before choosing the best way to connect the metals.The type of welding typically used for dissimilar metals is fusion welding, which welders also use for joining similar metals. In some instances, a welder may need to determine another method for joining dissimilar metals. For all these types of joining, the welder will need to consider:
1. The composition of the intermetallic layer.
2. The unmixed zone (UMZ) of base materials that did not combine into the intermetallic layer.
3. The heat-affected zone (HAZ)
