Learn how to set up and troubleshoot the HTP spool gun on MIG 1400i and 2000i welders, including wire installation, drive roll selection, and common mistakes.
Quick Answer
To set up the HTP spool gun on your MIG 1400i or 2000i, install the control board, mount the spool, thread the wire through the u-groove drive roll, and adjust tension to prevent birdnesting.
Why the right drive roll matters
Aluminum wire is soft and easily deformed by standard V-groove drive rolls, which can cause erratic feeding and burnbacks. The HTP spool gun uses a u-groove drive roll specifically designed for .030-.040 aluminum wire (4000 or 5000 series), so you get consistent wire feeding without crushing the wire.
If you plan to weld thicker aluminum, the 5000 series wire (like 5356) offers higher strength, while 4000 series (like 4043) is more fluid and crack-resistant. Both feed well with the u-groove roll as long as tension is set correctly.
Compatibility and control board
This spool gun is designed to work only with the HTP MIG 1400i and MIG 2000i welders. It includes the control board needed for operation, so you don't need to purchase a separate adapter. Make sure your welder model matches before installation.
The spool gun uses Binzel 15 series consumables, which are widely available and easy to replace. This keeps maintenance simple and ensures you can find tips and nozzles locally.
Step-by-Step Spool Gun Setup
- Install the control board: Connect the spool gun's control board to the welder's internal connector as per the manual. Ensure the welder is unplugged before opening the side panel. Secure the board firmly to avoid loose connections. Double-check that the board is fully seated; a loose connection can cause intermittent triggering.
- Mount the spool and thread the wire: Place the aluminum wire spool on the spindle, ensuring it rotates freely. Feed the wire through the inlet guide, then through the u-groove drive roll, and into the liner. Keep the wire straight to avoid kinks. Never let the wire unspool loosely; always keep tension on the spool to prevent tangling.
- Set drive roll tension: Adjust the tension knob so the drive roll grips the wire without slipping, but not so tight that it deforms the wire. A good test is to pull the wire by hand; it should slip slightly under firm pull. Start with low tension and increase gradually; overtightening causes birdnesting.
- Check the contact tip and liner: Use a contact tip sized for your wire diameter (e.g., .030 or .035). Ensure the liner is clean and free of debris. Replace the tip if it's worn or if the wire drags. A worn tip causes erratic arcs and burnbacks; replace it at the first sign of wear.
- Test the wire feed: With the welder on, trigger the spool gun and observe the wire feed. It should be smooth and consistent. If the wire stutters, check the drive roll alignment and tension. If wire feed issues persist, inspect the spool brake; too much drag will cause feeding problems.
Product Facts
- 20' Spool Gun, Only works with HTP® Mig 1400i and Mig 2000i Welders: The spool gun includes the board needed for use with either the MIG 1400i or MIG 2000i welder. You won't need to buy a separate adapter, saving time and ensuring plug-and-play compatibility with your HTP welder.
20' Spool Gun, Only works with HTP® Mig 1400i and Mig 2000i Welders - 20' Spool Gun, Only works with HTP® Mig 1400i and Mig 2000i Welders: The u-groove drive roller runs .030-.040 aluminum wire, 4000 or 5000 series. This drive roll is designed to feed soft aluminum wire without deformation, reducing the risk of jams and inconsistent arcs.
- 20' Spool Gun, Only works with HTP® Mig 1400i and Mig 2000i Welders: The barrel, drive motor, and cast aluminum drive box are built for durability. These components withstand the rigors of frequent aluminum welding, so the spool gun remains reliable on the job.
