This document is an internal Artisan's Asylum training document and is provided "as is", to be used as a reference only. Use of this document for any purposes other than as reference material (i.e., for the purposes of training and testing users on tools or equipment by other commercial entities or individuals) is not advised. In no event shall the authors of this material, or Artisan's Asylum, Inc., be liable for any claim, damages, or other liability whether in action or contract, arising from, out of, or in connection with the use of the information in this document for training, testing, or on-going safe use of fabrication equipment. Please consult your own lawyers and subject matter experts if you are looking to develop your own safety curriculum for fabrication equipment operation. Tool operators are responsible for their own safety, including reading and understanding the owners manual for this equipment and all of the warnings it contains.


Personal Protective Equipment

  • Standard shop personal protective equipment (no unrestrained long hair, no flowing clothes, closed-toed shoes) are required
  • All clothing should be 100% cotton; no plastic blends are allowed.
  • Either wear long-sleeve shirts or the leather cape sleeves that are available in the shop.
  • Wear cowhide TIG welding gloves.
  • Wear a welding mask rated to at least shade 12.
  • Wear safety glasses underneath your welding helmet to guard against flying sparks.
  • If necessary, wear ear plugs to guard against sparks flying into your ears.


  • Make sure there are no puddles on floor in welding area, particularly around machines and foot pedals.
  • Turn on your welding bay ventilation to an appropriate amount of time with the switch located in Bay 1.
  • Make sure that the welding area is free of flammable materials.
  • Attach the ground clamp to bare metal on the workbench (make sure it's the TIG welder's ground clamp, not the MIG's).
  • Plug in the machine.
  • Turn on the machine.
  • Twist the valve on the top of the argon tank three times, counterclockwise.
  • Hold the torch away from the workbench (more than 12 inches).
  • Depress foot pedal to start the gas cycle, then adjust the flow-meter or regulator - see individual machine pages for optimal settings.
  • Set the machine appropriately for either steel or aluminum - see individual machine pages for optimal settings.
  • Adjust welding screens to make sure no bystanders can be caught by arc-flash.
  • Adjust the placement of the foot pedal and your seat to make sure your position is comfortable.
  • Check tungsten electrodes to make sure they're clean.

Safe Operation

  • Make sure no bare skin is ever in contact with the workbench or workpiece during welding or while your parts are hot.
  • Clean tungsten electrodes as required on pedestal grinders.
  • Remove gloves if sharpening tungsten electrodes on pedestal grinders.
  • If switching to angle grinder operation, make sure your gloves will not be entangled in grinder operation.
  • Hold the torch and filler wire as appropriate to your weld position and requirements.
  • If the tungsten electrode touches the weld puddle during a weld, immediately stop welding and clean the tungsten.
  • Make sure your welding gloves are not in contact with the work during the weld.
  • Treat all work as if it is hot enough to burn you through your gloves.


  • Turn the valve on the argon tank clockwise, all the way closed.
  • Turn off the machine.
  • Turn off the flow meter or regulator - see individual machine pages for details.
  • Turn off the shop ventilation if nobody is using nearby bays.
  • Return all tunsgten, weld wire and tools.
  • Disconnect the ground clamp, coil cords and store neatly.
  • Clean the workbench.
  • Sweep up after yourself.

Allowable Materials

  • No galvanized, plated, painted, oiled, rusted, or powder coated metals are allowed.
  • All metal cleaning should be done with Simple Green or other low-intensity cleaners. No parts may be cleaned with brake cleaner at any time.
  • All Artisan's Asylum welding stock (i.e. 100% argon, filler wire, 2% thoriated tungsten) is intended to be used with mild steel. Each welder should have a kit of parts for .040", 1/16", 3/32", and 1/8" tungsten setups. Users are responsible for providing consumables for other metals.

First Aid Suggestions

  • If you burn yourself, immediately douse the area with cold (preferably running) water. Seconds count, to prevent significant burns.
