TIG Welding Trouble Shooting

The following addresses some of the common problems of DC TIG welding. In all cases of equipment malfunction, the manufacturer’s recommendations should be strictly adhered to and followed.

Tungsten Burning Away Quickly

Possible Reason Suggested Remedy
Incorrect Gas Check that pure Argon is being used
No gas Check the gas cylinder contains gas and is connected and the torch gas valve is open
Inadequate gas flow Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 21-30cfh flow rate
Back cap not fitted correctly Make sure the torch back cap is fitted so that the o-ring is inside the torch body
Torch connected to DC + Connect the torch to the DC- output terminal
Incorrect tungsten being used Check and change the tungsten type if necessary
Tungsten being oxidised after weld is finished Keep shielding gas flowing 10–15 seconds after arc stoppage. 1 second for each 10 amps of weld current.

 

Contaminated Tungsten

Possible Reason Suggested Remedy
Touching tungsten into the weld pool Keep tungsten from contacting weld puddle. Raise the torch so that the tungsten is off of the work piece 1/8-1/4in
Touching the filler wire to the tungsten Keep the filler wire from touching the tungsten during welding, feed the filler wire into the leading edge of the weld pool in front of the tungsten
Tungsten melting into the weld pool Check that correct type of tungsten is being used. Too much current for the tungsten size so reduce the amps or change to a larger tungsten

 

Porosity - Poor Weld Appearance and Colour

Possible Reason Suggested Remedy
Incorrect Gas Check that pure Argon is being used
Inadequate gas flow / gas leaks Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 21-30cfh flow rate. Check hoses and fittings for holes, leaks etc.,
Moisture on the base metal Remove all moisture from base metal before welding
Contaminated base metal Remove materials like paint, grease, oil, and dirt, including mill scale from base metal
Contaminated filler wire Remove all grease, oil, or moisture from filler metal.
Incorrect filler wire Check the filler wire and change if necessary

 

Yellowish Residue / Smoke on the Alumina Nozzle & Discolored Tungsten

Possible Reason Suggested Remedy
Incorrect Gas Use pure Argon gas
Inadequate gas flow Set the gas flow between 21-30cfh flow rate
Alumina gas nozzle too small for size of tungsten being used Increase the size of the alumina gas nozzle

 

Unstable Arc During DC Welding

Possible Reason Suggested Remedy
Torch connected to DC + Connect the torch to the DC- output terminal
Contaminated base metal Remove materials like paint, grease, oil, and dirt, including mill scale from base metal.
Tungsten is contaminated Remove 10mm of contaminated tungsten and re grind the tungsten
Arc length too long Lower torch so that the tungsten is off of the work piece 2 - 5mm

 

Arc Wanders During DC Welding

Possible Reason Suggested Remedy
Poor gas flow Check and set the gas flow between 21-30cfh flow rate
Incorrect arc length Lower torch so that the tungsten is off of the work piece 1/8-1/4in
Tungsten incorrect or in poor condition Check that correct type of tungsten is being used. Remove 1/2in from the weld end of the tungsten and re sharpen the tungsten
Poorly prepared tungsten Grind marks should run lengthwise with tungsten, not circular. Use proper grinding method and wheel.
Contaminated base metal Remove contaminating materials like paint, grease, oil, and dirt, including mill scale from base metal.
Contaminated filler wire Remove all grease, oil, or moisture from filler metal.
Incorrect filler wire Check the filler wire and change if necessary

 

Arc Difficult To Start or Will Not Start DC Welding

Possible Reason Suggested Remedy
Incorrect machine set up Check machine set up is correct
No gas, incorrect gas flow Check the gas is connected and cylinder valve open, check hoses, gas valve and torch are not restricted. Set the gas flow between 10 - 15 l/min flow rate
Tungsten is contaminated Remove 10mm of contaminated tungsten and re grind the tungsten
Incorrect tungsten size and or tungsten being used Check and change the size and or the tungsten if required
Loose connection Check all connectors and tighten
Earth clamp not connected to work Connect the earth clamp directly to the work piece wherever possible

 

Important: We strongly recommend that you check for gas leakage prior to operation of your machine. We recommend that you close the cylinder valve when the machine is not in use. Coreone as authorized representative of the manufacturer will not be liable for costs incurred due to gas leakage.

 

ATTENTION! - CHECK FOR GAS LEAKS

At initial set up and at regular intervals we recommend to check for gas leakage.

Recommended procedure is as follows:

  • Connect the regulator and gas hose assembly and tighten all connectors and clamps.
  • Slowly open the cylinder valve.
  • Set the flow rate on the regulator to approximately 21-30cfh.
  • Close the cylinder valve and pay attention to the needle indicator of the contents pressure gauge on the regulator, if the needle drops away towards zero there is a gas leak. Sometimes a gas leak can be slow and to identify it will require leaving the gas pressure in the regulator and line for an extended time period. In this situation it is recommended to open the cylinder valve, set the flow rate to 21-30cfh, close the cylinder valve and check after a minimum of 15 minutes.
  • If there is a gas loss then check all connectors and clamps for leakage by brushing or spraying with soapy water, bubbles will appear at the leakage point.
  • Tighten clamps or fittings to eliminate gas leakage.

MIG Welding Trouble Shooting

The following addresses some of the common problems of MIG welding. In all cases of equipment malfunction, the manufacturer’s recommendations should be strictly adhered to and followed.

Change the Post Flow

COREMIG Series How to Change the Post Flow
5 Step Process
  • Press and hold the 2T/4T switch key on the front panel and do not release it. Then, turn on the power switch of the welding machine, then release 2T/4T switch key.
  • When the display window displays "P1", release the 2T/4T switch key to enter into the system parameter altering interface.
  • Turn the Amperage knob until it reads "P5".
  • Turn the Amperage knob until it reads "P5". 4. Turn the Voltage knob up or down to increase or decrease the amount of post flow gas that comes out of mig gun when trigger is released.
  • After the parameter altering is done, press the 2T/4T switch key again to store the system parameters. This will memorize your selection.

Excessive Spatter

Possible Reason Suggested Remedy
Wire feed speed set too high Select lower wire feed speed
Voltage too high Select a lower voltage setting
Wrong polarity set select the correct polarity for the wire being used - see machine setup guide
Stick out too long Bring the torch closer to the work
Contaminated base metal Remove materials like paint, grease, oil, and dirt, including mill scale from base metal
Contaminated mig wire Use clean dry rust free wire. Do not lubricate the wire with oil, grease etc
Inadequate gas flow or too much gas flow Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 21-30cfh flow rate. Check hoses and fittings for holes, leaks etc Protect the welding zone from wind and drafts

 

Porosity - Small Cavities or Holes Resulting from Gas Pockets in Weld Metal.

Possible Reason Suggested Remedy
Wrong gas Check that the correct gas is being used
Inadequate gas flow or too much gas flow Check the gas is connected, check hoses, gas valve and torch are not restricted. Set the gas flow between 21-30cfh flow rate. Check hoses and fittings for holes, leaks etc. Protect the welding zone from wind and drafts
Moisture on the base metal Remove all moisture from base metal before welding
Moisture on the base metal Remove all moisture from base metal before welding
Contaminated base metal Remove materials like paint, grease, oil, and dirt, including mill scale from base metal
Contaminated mig wire Use clean dry rust free wire. Do not lubricate the wire with oil, grease etc
Gas nozzle clogged with spatter, worn or out of shape Clean or replace the gas nozzle
Missing or damaged gas diffuser Replace the gas diffuser
Mig torch euro connect o-ring missing or damaged check and replace the o-ring

 

Wire Stubbing During Welding

Possible Reason Suggested Remedy
Holding the torch too far away Bring the torch closer to the work and maintain stick out of 5-10mm
Welding voltage set too low Increase the voltage
Wire Speed set too high Decrease the wire feed speed

 

Lack of Fusion − Failure of Weld Metal to Fuse Completely with Base Metal or a Proceeding Weld Bead.

Possible Reason Suggested Remedy
Contaminated base metal Remove materials like paint, grease, oil, and dirt, including mill scale from base metal
Not enough heat input Select a higher voltage range and /or adjust the wire speed to suit
Improper welding technique Keep the arc at the leading edge of the weld pool. Gun angle to work should be between 5 & 15° Direct the arc at the weld joint Adjust work angle or widen groove to access bottom during welding Momentarily hold arc on side walls if using weaving technique

 

Excessive Penetration − Weld Metal Melting Through Base Metal

Possible Reason Suggested Remedy
Too much heat Select a lower voltage range and /or adjust the wire speed to suit. Increase travel speed

 

Lack of Penetration − Shallow Fusion Between Weld Metal and Base Metal

Possible Reason Suggested Remedy
Poor in incorrect joint preparation Material too thick. Joint preparation and design needs to allow access to bottom of groove while maintaining proper welding wire extension and arc characteristics. Keep the arc at the leading edge of the weld pool and maintain the gun angle at 5 & 15° keeping the stick out between 1/8-1/4in
Not enough heat input Select a higher voltage range and /or adjust the wire speed to suit. Reduce travel speed
Contaminated base metal Remove materials like paint, grease, oil, and dirt, including mill scale from base metal.

 

No Wire Feed

Possible Reason Suggested Remedy
Wrong mode selected Check that the TIG/ARC/MIG selector switch set to MIG position
Wrong torch selector switch Check that the STANDARD/SPOOLGUN selector switch is set to STANDARD position for MIG welding and SPOOLGUN when using the Spoolgun

 

Inconsistent / Interrupted Wire Feed

Possible Reason Suggested Remedy
Adjusting wrong dial Be sure to adjust the WIRE FEED and VOLTAGE dials for MIG welding. The AMPERAGE dial is for STICK and TIG welding mode
Wrong polarity selected Select the correct polarity for the wire being used - see machine setup guide
Incorrect wire speed setting Adjust the wire feed speed
Voltage setting incorrect Adjust the voltage setting
Mig torch lead too long Small diameter wires and soft wires like aluminium don’t feed well through long torch leads - replace the torch with a lesser length torch
Mig torch lead kinked or too sharp angle being held Remove the kink, reduce the angle or bend
Contact tip worn, wrong size, wrong type Replace the tip with correct size and type
Liner worn or clogged (the most com - mon causes of bad feeding) Try to clear the liner by blowing out with compressed air as a temporary cure, it is recommended to replace the liner
Wrong size liner Install the correct size liner
Blocked or worn inlet guide tube Clear or replace the inlet guide tube
Wire misaligned in drive roller groove Locate the wire into the groove of the drive roller
Incorrect drive roller size Fit the correct size drive roller eg; .030in wire requires .030in drive roller
Wrong type of drive roller selected Fit the correct type roller (e.g. knurled rollers needed for flux cored wires)
Worn drive rollers Replace the drive rollers
Drive roller pressure too high Can flatten the wire electrode causing it to lodge in the contact tip - reduce the drive roller pressure
Too much tension on wire spool hub Reduce the spool hub brake tension
Wire crossed over on the spool or tangled Remove the spool untangle the wire or replace the wire
Contaminated mig wire Use clean dry rust free wire. Do not lubricate the wire with oil, grease etc
