| Symptom | Likely Cause (per manual) | Solution | |---------|---------------------------|----------| | No arc, motor runs | Loose work clamp or broken internal control relay | Tighten ground. If relay clicks but no weld, replace relay (part #WF-70-RLY). | | Wire feeds but no arc | Poor contact at gun trigger switch | Disassemble gun handle; clean micro-switch contacts. | | Erratic wire speed | Worn drive roll or incorrect spool brake tension | Flip/replace drive roll; adjust spool’s thumb-screw to allow slight drag. | | Overheating (thermal light on) | Exceeded 20% duty cycle (2 min weld / 8 min cool) | Let fan run. Manual states: Never override the thermal breaker. | | Bird-nesting at drive roll | Gun liner debris or excessive drive roll pressure | Blow out liner with compressed air; reduce pressure to just before slipping. |

: Loosen until the spool barely starts to unwind, then tighten until it stops spinning within 1/2 a revolution.
: Requires the optional gas conversion kit (2111) and uses .024" (0.6mm) diameter ER70S-6 wire.
: Maintain a nearly vertical gun angle, with only a 15-degree tilt in the direction of travel. For flux-core welding, use a "drag" technique (the saying is "if it slags, it drags"). Safety & Maintenance Century Power-Mate 70 polarity setup for self-shield FCaW
