Operating Instructions and Parts Manual | WS4369 and WS4469 |
|
|
Disconnect power supply and turn
machine off before inspecting or servicing any components.
Before Every Use:
1.Check condition of weld cables and immediately repair or replace any cables with damaged insulation.
2.Check condition of power cord and immediately repair or replace any cord if damaged.
3.Check condition of electrode holder insulating pieces and immediately replace cracked or missing insulators. Verify that all fasteners are tight and insulated.
Do not operate this welding machine
with cracked or missing insulation on welding cables, electrode holder, or power cord.
Every 3 months:
Replace any unreadable labels on the welder. Use compressed air to blow all dust and lint from the ventilation openings.
Symptom | Possible Cause(s) | Corrective Action | ||
Welder does not hum when | 1. | No power at receptacle | 1. | Check circuit fuse or circuit breaker |
turned on | 2. | Broken or damaged power cable | 2. | Power cable requires service |
|
|
|
|
|
Welder hums but does not | 1. | Inadequate current at electrode | 1. | Check ground clamp, cable and connection to work piece. |

| Check electrode cable and clamp. |
| 2. | Poor connections at welder | 2. | Check all welder external connections |
|

|
Welder gives trickle shocks | 1. | Accidental contact with work piece | 1. | Avoid contact with work piece |
| 2. | Current leakage caused by moist | 2. | Make sure clothing and work area are dry |

|
Welder overheats - blows | 1. | Use of extension cord | 1. | If possible, relocated welder to avoid use of extension cord. If |
fuses, trips circuit breaker |
|
|
| relocation of welder is not possible, use thicker (lower gauge |
|
|
|
| number) extension cord |
| 2. | Electrode diameter too large | 2. | Use smaller diameter electrode |
| 3. | Overloaded circuit | 3. | Welder requires a dedicated 230v circuit |
|
|
|
|
|
Arc difficult to strike | 1. | Electrode diameter too large | 1. | Use smaller diameter electrode |
| 2. | Work piece not properly grounded | 2. | Verify proper grounding. (No paint, varnish or corrosion) |
| 3. | Heavy loads making power line | 3. | Run welder on dedicated 230v circuit |

|
|
Ragged depressions at edge | 1. | Travel speed too fast | 1. | Decrease travel speed |
