Solar 2150 Wire Feed Welder Manual
First, a critical piece of history: The was manufactured under the Solar brand, which was eventually acquired by Century Manufacturing Company in the 1990s. Century was itself later purchased by the industry giant, Lincoln Electric , in 2003. This corporate chain of custody means that original Solar manuals have become exceedingly rare, and factory technical support has long since ceased.
30A to 150A (adjustable via tap settings or variable dials, depending on the exact sub-model year).
Flip down the tension arm and feed the wire manually through the inlet guide into the gun liner. Lock the tension arm back into place. Turn the tension knob until it holds firmly.

Over time, metal dust and shavings accumulate inside the torch liner. Every few spool changes, blow out the liner with compressed air from the machine end out toward the torch tip. Troubleshooting Common Issues Probable Cause Corrective Action Wire slips or doesn't feed
Solar 2150 (Model 117-051) is a 110-amp MIG wire feed welder designed primarily for light-duty applications like auto body repair. While original printed manuals are often out of stock, you can find a Digital Copy of the Solar 2150 Manual through various online archives. Century Tool & Equipment Key Specifications & Features Welding Capacity : Capable of welding steel from 26 gauge up to in a single pass. Wire Support : The unique wire feed mechanism handles -inch wire. Feed Speed : Infinitely adjustable from 50 to 700 inches per minute. Adjustment Controls First, a critical piece of history: The was
Most wire-feed welders, including the Solar 2150, can use two types of welding wire. Your machine's manual likely has a page dedicated to switching between them.
Even a well-maintained Solar 2150 will develop issues. Here is the official troubleshooting guide condensed from typical sections.
| Symptom | Probable Cause | Solution | | :--- | :--- | :--- | | | Wire feed tension too tight; Liner worn; Wrong tip size. | Reduce tension; Replace liner; Check tip size. | | Porosity (Holes in weld) | Lack of shielding gas; Wind drafts; Dirty metal. | Check gas flow; Move away from fans; Clean metal. | | Erratic Arc / Stuttering | Loose ground clamp; Worn contact tip; Kinked liner. | Tighten ground; Replace tip; Replace liner. | | No Arc / Wire not feeding | Wrong polarity (usually); Fuse blown; Gun lead disconnected. | Check polarity (+ for Flux Core, - for Solid Wire usually). | | Excess Spatter | Voltage too low for wire speed; Wrong gas mix. | Tune voltage up; Verify gas mix (75/25). | 30A to 150A (adjustable via tap settings or
The Solar 2150 must be configured with the correct polarity depending on whether you are using shielding gas or gasless flux-cored wire. Incorrect polarity results in massive amounts of spatter and zero weld penetration.
: Features an internal thermal overload switch that halts welding and triggers a cooling cycle if the duty cycle is exceeded. 2. Crucial Safety Precautions
: Adjust the tension knob so the roller grips the wire without crushing it.
The Solar 2150 wire feed welder manual provides detailed instructions for operating the machine. Here's a step-by-step guide:
Check gas regulator/cylinder; weld indoors; switch polarity to DCEP for gas.
