Very little power at wire


try to use bare .032 wire and co2 shielded gas, If the equipment does not have a gas solenoid you may have to wire a solenoid to the trigger mechanism to get the gas to flow while the wire is feeding. The bare wire usually copper coated burns much hotter than the flux core when there is a gas shield. Also a .032 bare wire with a gas shield burns a a lower amp range and will get better penetration.

You may have to experiment with the feed rate and gas flow to get the correct setting, but the bare wire has a lot less resistance to current flow than the flux core and will burn a lot hotter when you use a gas shield.

At 115 vac there is not a lot of amperage left to create an arc and run the feeder and the rest of the unit , and the flux core wire takes a lot of amperage to burn both the wire and the flux . .

Craftsman 580 767101 when i squeeze the handle pressure it loses pressure. If i squeeze i get a burst of pressure, it then fades out. Relese the handle and squezze i get another burst


Sounds like the inlet water source may be blocked. When you hold the trigger open, water should flow freely. If this is not the problem, it may be that the pump seals are going bad.

I have a hobart 135 handler that with machine plugged in and turned on the wire has constant juice and the gas cylonoid is flowing gas from the bottle without the trigger being pressed. my dealer said it...


Hi:
Have you disconnect the gun's power plug? If the wire and gas stop flowing by doing this action, then your problem is the gun's trigger. If the machine continues to feed gas and wire with the gun disconnected then yes, it is the pc board.
Good luck.

Squeeze trigger once and it fires 3x


if there is a 9 volt battery in the handle, there should be 3 to 5 small dip switchesright by the battery, your set on 3 shot burst, unhook the gas, turn all switches off, and test it, there is also a full auto setting, try different combinations untill you get single shot

The millermatic 135 gun has stopped working. Could this be from the switch going out?


If the switch is dead, the gun will not work. Pulling the trigger tells the machine to initiate delivery of the wire, gas and current. If the switch is dead, none of that will happen.

Gas quits flowing almost emmediately after a short burst?


You don't want it running more that a couple of seconds after. That only wastes the gas. It is a shielding gas and is only needed when lay a bead, one /two seconds after ending pass is reasonable.

I tried to adjust the regulator and the back just screwed off of the body - any ideas on how to prevent that?


Possibly you were trying to adjust the regulator without having air flowing through it. You must squeeze the trigger on the gun and have air constantly flowing through it otherwise the regulator knob is very hard to turn against the pressure inside it. To set an accurate pressure, squeeze gun trigger (while connected to air hose) to get air flowing... then twist regulator knob out (or in the "-" direction) until air flow reads 0 on the regulator gauge. Then start twisting regulator knob the other way until you reach the desired pressure on the regulator gauge. Also make sure the regulator is attached with air flowing the correct way through it. There should be an arrow somewhere on the regulator body which should be pointing toward your spray gun.
