About on-site / mobile welding
Do mobile rigs do all kinds of welding?
Most carry MIG, TIG, and stick capability. Smaller rigs may not have everything for aluminum or stainless work — call ahead to confirm the process for your project.
What's a trip charge?
A fixed fee that covers travel to the site. Usually $50–$200 depending on distance. The hourly labor starts when work begins, not when the truck leaves the shop.
