Have a solar 2160 wire feed welder but do not seem to have any heat control.can't weld sheet metal,just way to hot.

You say the current is too high. What is the problem that makes you say that? Is it trying to burn through? What does the control panel label say? Something like power and another that says wire feed speed?
The current is a function of wire speed. The faster you feed the wire, the more current is drawn from the machine.
To get less current drawn, you must slow down the wire.
After this is getting better, you may have to change the other control that actually is a voltage control. Too high a voltage give too much heat for the thickness of the metal and too low will not let the bead lay down and look nice.

Let me know if you are happy with the way it works now.

P.S. It will work much better with .025 wire. 035 wire will be too large for 1.5mm material.

read you hand book on the settings but it all depends on material thickness being welded
higher volts = higher amps will require faster feed speeds = thicker materials
sheet metal thickness (.040"-1mm) will require very low volts -up to 20 v with a slower feed speed
remember the unit will have a very short duty cycle and that means that you cannot start a weld and keep it going for many minutes especially at high amps
it works like this ,if it is a 20% duty cycle ( on the plate of the machine then for every 20 seconds of power ( high amps) the machine has to rest for 80 seconds
if you are welding panel metal the ( very low amps) then you can weld for longer periods but the rest period has to be 4 times the weld period

Sounds like a power or ground issue ie. not enough power or a poor ground circuit

Check to see if the wire feed pressure is set correctly. Sounds like it's a little loose.

check for circuit breaker by drive motor, it may be the pc board.

If wire pushes your hand away when welding you need to do one of the following:
Reduce your wire speed, or increase the voltage.

you should run power between 160-180 to get a godd weld with out burning your work

I have the same welder. Worked well for 15 years until the drive bearing stopped spinning. I cleaned and oiled the bearing and it has been working like a coon on the farm since. Nice 120 volt welder....

If you are using flux wire and not shielding gas, your clamp should be positive and the wire should be negative. Heat is provided by the electrical arc that happens between the wire and the material. Your welder by itself does not pre heat the material and with 3/16 material you should not need to preheat anyway.

The electrical arc is kept consistent by adjusting the wire feed rate and the current applied. You will need to experiment with these settings to find what works best with your welder. For this welder and 3/16 material, I would suggest you start at the upper end of the current scale and about a third of the way up on wire speed. The welder might have a chart for these settings in the manual or inside cover.

If the wire feeds too fast, it will push the probe around and you will feel pressure as the wire feeds out. If the speed is too slow you will get large spatters and intermittent arcs. When properly adjusted the arc will sound even and consistent. The arc gap should always be about 1/8 of an inch.

To maintain enough heat for good penatration, do not move the probe too fast, work in a pattern and watch the weld pool (melted metal) and not the arc. Watching the weld pool will clue you in if you are moving too fast or too slow.

I hope this helps.

For certain type of work TIG is required, like welding chrome moly for some racing organizations. Intricate work, like gunsmithing is also well suited to TIG. TIG is used by many auto restorers who prefer a more precise, perfect finish that requires little to no finish work. TIG is most similar to gas welding in technique, so if you've done oxy-fuel welding, TIG should be a natural transition. MIG is required by law and by insurance companies in many localities for structural repair of automotive frames. MIG is also much easier to learn and faster to weld. For doing other types of welding, like sheet metal, it can be a matter of personal preference. For an auto body repair shop or a novice welder, a MIG is a good, practical all-around welder.
