You may not have a good ground or you may need to turn the voltage up for this grade of wire. Check the ground cable at the machine and where the ground wire connects to the ground clamp.

Try cleaning the feed rollers and the groove in the rollers. The liner may also need to be replaced or lubricated. This is also a problem when you need to replace the tip.

First Im'm not a Chicago Machine representative. * check your warranty or ID plate for contact info. * Call for support. *** Following is for information only.*** * Though there is no model number. Most of the info comes up as a 90 amp welder. These welders are very common. They are available under different brands and distributors. They are all from China. * Wire Welder, 90 Amp Flux Chicago Electric Welding - Item#68887; https://www.youtube.com/watch?v=K8GS2IvTlRw * $99 125 amp welder. Worth it? new 90 a.

I wish I bought the 110 VAC stick welder. I know it's less power but it's way simpler to use and set up. More fun but really ugly welds. But I get the same result with the Mig but with more hassle. * Here is the manual for yours; https://manuals.harborfreight.com/manuals/68000-68999/68181.pdf * Have fun! Aloha, ukeboy57

possible reasons include worn liner in cable grabbing wire, worn size wire for the rollers fitted , wire speed not fast enough ( adjust) wrong size wire for the liner in use rust off the wire jamming the wire in the liner

the gas to use is determined by the material being welded an argon mix for steel based metals or straight argon for aluminum Talk with your gas supplier to get the right gas for the job

get a lower melting point solder get a higher temp tip if so equiped get a higher wattage iron.

* Check your warranty and call for service. *** Following is for information only *** * welders require cooling of the power diodes used to convert AC (alternating current) to DC (Direct current). * The fan can be DC powered but it's common to have a common AC fan. They are usually connected to a control board to turn on when things get hot. * But this control is really not required as the fan should always be on even when not welding as any residue heat needs to be removed for continuous or longer duty cycles. (how long can you weld without stopping.) * D.I.Y. People tend to upgrade the fan with a heavy duty blower or at least a larger (higher CFM) fan if it can be mounted in or on the welder. * Lots of upgrade examples on you tube. * Need Brand and model number for specific information. * Here is a sample of common upgrades; * Tips, Tricks, upgrades; https://www.youtube.com/user/WeldFever/featured * Trouble shooting; https://www.youtube.com/watch?v=ahf2oggp8qY * Extend Duty Cycle; https://www.youtube.com/watch?v=HK4KcYmBGDc * Final, If your not sure. Be safe, call for service. Aloha, ukeboy57

This is basically a home type emergency generator. It is anybody's guess as what is wrong. If the covers were off and I was there with a meter I bet I could tell you the problem . Could be brushes stuck, a bad regulator, or bad exciter diode, depending on the design.

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.

the maximum size rod it will run and the duty cycle at full load the duty cycle is the length of time it will weld before the overload cuts in and stops the weld

Sorry I can't help much. I am not familiar with the device. A genuine arc welder of that vintage will be heavy and bulky as it would contain a heavy duty transformer. There have been devices and gadgets that attempted to offer the advantages of an arc welder without the disadvantages of bulk, weight and expense, with varying degrees of success. I expect your device is not complete. In my limited experience such devices had a special electrode holder that vibrated during use. This allowed an arc to be produced and welding to be possible without the large current and voltage flow a transformer would provide.
