COMMON SENSE ANSWERS FOR THE WELDING FABRICATION INDUSTRY
LINCOLN® REPLACEMENT ARMATURES FOR THE SA-200 PIPELINER, SA-250, SAE-300, and SAE-400 ENGINE DRIVEN WELDERS
A) Lincoln Exciter Armature
LINCOLN DC ARMATURE LOCATER
WELDMART REWOUND DC EXCITER ARMATURE
SA-250/CLASSIC 1,2,& 3 AC EXCITER ROTOR
SAE-300 & 400 AC EXCITER ROTOR
Exciter armatures tend to fail at a "high" rate. We stock rebuild exciter armatures and AC Field frames. We ask that you send us your rebuild able core. If your core is rebuild able we will credit your account. Please contact with your armature question.
B) The Lincoln Main Armature
The graphic below is a main armature although you cannot tell from the picture this armature is defective. This armature has a "short" between the one of the windings and the metal core.
WELDMART REWOUND MAIN ARMATURE FOR SA-200/SA-250/SAE-300, & SAE-400 ENGINE DRIVEN WELDERS.
FIVE-YEAR LIMITED WARRANTY!
SITUATION A: If your armature is old, but still "GOOD" (or you think it's all right), this is what we can do for you. Be aware that your machine can weld just fine, but have defective windings. Send your armature to us and let us test it. If it has no shorts we can recondition it. When we say "recondition" the following our standard procedure:
1. Chemically clean the entire unit (remove any oil, grease, dirt, and mud dobber nests)!
2. Check and repair any broken connections.
3.. We remove the steel bands. Steel bands are easy to install when manufacturing an armature. The problem is that over time the bands rust and break. At 1500 Rpm's a broken band makes one hell of a racket and tears up your stator-fiberglass bands will never rust & break!
4. Dip and bake the armature.
5. Machine the communicator, (makes it level so the brushes run smooth and true).
6. Under cut the communicator slots to make sure they are all the same depth.
7. All repaired and rewound armatures are dynamically load tested (250 amps for a minimum of one hour!).
SITUATION B: If your armature is dead, shorted burnt, or whatever. Here what we can do in this situation.
1. Chemically clean the entire unit (remove any oil, grease, dirt, and mud dobber nests)!.
2. Strip steel bands and the windings off the armature, (the armature is stripped down to bare metal and checked for any defects, mechanical or electrical). At this point the core is inspected and we determine if the core is rebuild able.
3. Check the communicator, make sure it is good (there is no insulation breakdown).
4. Install all new copper bars with Dupont®.Nomex® insulation (We do use paper insulation!). The armature is then dipped in "Class H" insulation, then baked.
6. Machine the communicator and rework the communicator slots to make sure they are all the same depth.
7. All repaired and rewound armatures are dynamically load tested (250 amps for a minimum of one hour!).
