The Hobart 770502 is a medium-duty oxy-acetylene cutting and welding outfit that includes a torch handle, cutting attachment, tips, regulators, twin hose and goggles. It is worth considering if you want a name-brand starter kit for light welding and cutting up to about 1/2 inch steel, and it is not meant for heavy plate. This Hobart 770502 oxy-acetylene kit review uses Hobart’s published specs and the Amazon listing, not hands-on testing.

What it is and who it suits
The 770502 is a Victor-style medium-duty outfit with the parts needed to start cutting and welding, except for cylinders. It suits hobbyists, farm and garage users and light fabricators.
It is not intended for thick plate or all-day production cutting. For comparison, see the Victor CA2460 and CA2470 torch kit, the LuckyHigh oxygen acetylene cutting torch kit and the lighter G150-J-P portable kit.
How to check it fits your needs
- Match thickness. Compare your usual material with the 1/2 in cutting and about 3/32 in welding figures. Larger work needs bigger tips and regulators.
- Plan your cylinders. Cylinders are not included. Check the supplier’s sizes and the regulator inlet (CGA) fittings.
- Check tip style. Victor-style tips are common, but always verify the tip and torch series.
- Check fuel gas. Acetylene is standard. Propane requires different tips and a compatible regulator.
- Review accessories. The included #5 goggles are a basic option. Many users prefer a face shield or goggles with the shade appropriate for their work.
Pros and limitations
Pros
- Complete outfit apart from cylinders.
- Check valves in the handle and optional torch-mounted arrestors add backflow protection.
- 20 ft twin hose gives useful reach.
- Common torch and tip style helps with replacement parts.
Limitations
- Capacity is limited for thick steel.
- Cylinders, cart and spare tips cost extra.
- Small 3/16 in hose limits flow for larger tips.
- Gas welding steel needs practice, and it is slower than arc welding.
Setup and safety tips
- Chain cylinders upright and keep oxygen away from oil and grease.
- Fit regulators, hoses and arrestors, then leak test with soapy water.
- Keep acetylene working pressure at or below 15 psi, and use the tip chart for oxygen.
- Purge each line, light acetylene first, then bring in oxygen to a neutral flame.
- Wear eye protection with an appropriate shade, leather gloves and fire-resistant clothing.
- Do not cut or weld closed containers or tanks that held fuel.
- Shut the cylinders and bleed the lines after use.
Alternatives and related guides
- CDL LX45 oxygen regulator if you want a separate regulator.
- 1/4 x 50 ft twin welding hose for longer reach.
- Oxygen cylinder wrench for opening cylinders.
Frequently Asked Questions
How thick can the Hobart 770502 cut and weld?
Hobart’s product page lists cutting up to 1/2 inch with the included #0 cutting tip, and welding up to about 3/32 inch with the included #0 welding tip. Other tips extend the range, so check the tip chart. Claims of much thicker capacity should be treated with caution.
Does the Hobart 770502 include gas cylinders?
No. Hobart’s listing says cylinders are not included, so you must supply oxygen and acetylene cylinders (or propane with correct tips) and be able to secure them. Check the CGA connection on your cylinders against the regulators.
Can the kit run on propane?
Hobart lists acetylene or propane as fuel options, but switching fuels requires a different tip. Fuel-gas regulators and tips are fuel-specific, so confirm that your regulator and hose are suitable before you use propane.
What safety equipment is included?
The kit includes torch-mounted check valves, optional flashback arrestors, and flip-front #5 shade goggles per Hobart’s description. Add a proper face shield or goggles, leather gloves, fire-resistant clothing, a fire extinguisher and regular leak tests.
Conclusion
The Hobart 770502 is a practical medium-duty starter outfit for light cutting and welding, so long as you plan for cylinders and a safe setup. Check the capacity figures against your own work.
