5.04 Specific Problems
How to Use this guide
The following information is a guide to help you determine
the most likely causes for various symptoms.
This guide is set up in the following manner:
A. Symptom (Bold Type)
Any special instructions (Text Type)
1. Cause (Italic Type)
a. Check/Remedy (Text Type)
Locate your symptom, check the cause(s) (the simplest
or most likely is listed first), then perform the remedy
given. Repair as needed being sure to verify that the unit
is fully operational after any repairs.
A. No Weld Output; Unit is Completely Inoperative
1. Line disconnect switch is in OFF position
a. Place line disconnect switch in ON position.
2. Line fuse(s) open
a. Check and replace line fuse(s).
3. Improper electrical input connections
a. See Section 3.01 Electrical Input Requirements,
page 3-1, for proper input connections.
4. MAIN CIRCUIT BREAKER in OFF position
a. Check and reset MAIN CIRCUIT BREAKER if
necessary.
5. INPUT SELECTOR (Easy Link) switch is set
to incorrect position for applied input voltage,
208/230/460 model only
a. Verify primary source voltage and set INPUT
SELECT switch to correct setting.
B. WARNING Indicator is ON
1. Unit is in thermal shutdown mode
a. Allow cooling period of approximately five (5)
minutes with the power ON. Duty cycle should
be reviewed. To reset the WARNING indicator,
the power supply must be turned OFF, then ON
again.
2. Input voltage is low
a. Measure input voltage and verify that it
matches the INPUT SELECTOR (Easy Link)
switch setting. The length of the input power
cable must be considered, as there will be a
considerable voltage drop along its length.
3. Erratic input voltage – spikes over tolerance will
cause the warning light to come on for protection
a. Turn MCB off then on to reset the warning light.
C. Erratic or Improper Weld Output
1. Loose welding cable connections
a. Tighten all welding cable connections.
2. Incorrect welding cable size
a. Use proper size and type of cable.
(see Operating Manual 0-2514)
3. Improper input connections
a. Refer to Section 3.1 Electrical Input
Requirements, page 3-1.
4. Poor electrode condition
a. Replace electrode.
5. If in GTAW mode, check the condition of the
tungsten electrode
a. Use the recommended 2% Thoriated tungsten.
6. In GTAW mode, incorrect argon gas flow
a. Verify that argon gas flow is correct;
approximately 12 SCFH.
7. Incorrectly set PROCESS SELECTOR switch
a. Verify the PROCESS SELECTOR switch is set
to match the type of welding process being
conducted.
8. Wrong welding polarity
a. Verify output torch connections.
