The Competitive Edge

This Welding Machine is built to our rigorous specifications and manufactured in compliance to CAN/CSA 60974.1

The full TIG functionality, offers simple step by step digital control of functions and parameters providing complete professional control. HF arc ignition provides Pre Gas with instant arc ignition leaving no tungsten inclusion or contamination of the tungsten electrode. Digital set-up of Pre-Gas Flow Time, Start Current, Up Slope and Down Slope Time, Finish Current Level and Post Gas Flow Time with the choice of 2T or 4T trigger function allows control of the welding process at a professional level from start to finish. Digital Pulse Control gives full parameter setting of Peak & Base Current, Pulse Frequency & Pulse Width providing control of heat input, penetration & distortion. AC Square Wave Balance gives control of the electron flow at the tungsten, the AC TIG arc can be adjusted from maximum oxide-layer cleaning on aluminum through to a deeper penetrating weld. Remote Control Interface provides remote amperage control at the footpedal control. The Selectable Tungsten feature allows the user to initiate softer arc starts when using small tungsten with thin metals avoiding burn through on their work. When using a larger tungsten it requires a larger initial current and by selecting a larger tungsten size it avoids arc stutter or lack of arc initiation. DC ARC welding delivers a smooth and stable arc for easy welding of electrodes producing high quality welds including cast Iron, stain-less and low hydrogen. Arc Ignition and Arc Force control allows you to set the ideal arc condition no matter what electrode you choose. Optimized auto protection of the power input provides auto shut down of the machine when large scale fluctuations occur. Unique air channel design increases the heat dissipation of the power device, control circuits, minimizes dust absorption, thereby greatly improving longevity and reliability.

Trouble Shooting TIG Welding

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.
