To set up the Clarke 6012147 AT135 for TIG welding, ensure the power is off. Connect the TIG torch to the negative terminal and the work clamp to the positive terminal. Attach the gas hose to the regulator and set the flow rate. Select the TIG mode on the welder, and adjust the amperage according to material thickness.
If the arc is not starting, first check the grounding clamp connection. Ensure the tungsten electrode is sharp and correctly positioned. Verify the gas flow and that the correct settings are chosen. Inspect cables and connections for damage or looseness.
Regularly clean the welder's exterior and vents to prevent dust buildup. Inspect cables and connections for wear. Replace consumables like electrodes and nozzles as needed. Store the unit in a dry, clean environment.
For welding mild steel, set the Clarke 6012147 AT135 to the MMA mode. Use an electrode suitable for mild steel, typically E6013 or E7018. Adjust the amperage based on electrode diameter, usually between 60 to 120 amps.
Overheating can be caused by exceeding the duty cycle or insufficient ventilation. Ensure the welder is used within its duty cycle limits and place it in a well-ventilated area to prevent overheating.
Always wear appropriate personal protective equipment, such as gloves, helmet, and apron. Ensure good ventilation in the working area to avoid inhaling fumes. Check all connections and cables for safety before use.
To adjust the amperage, turn the power switch on and use the control knob on the front panel to set the desired amperage level. Refer to the material and electrode specifications to choose the correct amperage range.
The Clarke 6012147 AT135 is primarily designed for steel and stainless steel. For aluminum, you would need a specific setup with an AC TIG welder and possibly a spool gun for optimal results.
Inconsistent weld beads can result from incorrect settings, poor electrode condition, or unstable hand movements. Ensure proper settings and technique, and inspect the electrode for wear or contamination.
First, turn off the welder and disconnect the torch. Unscrew the back cap, remove the old electrode, and insert a new tungsten electrode. Ensure it's properly aligned and protrudes slightly from the gas nozzle before reassembling the torch.
